Introduction

The BAST-321HP-BW2 is a member of the BASstat BACnet Communicating Thermostat series. It provides multi-staged heating and cooling control in an attractive wall-mounted enclosure with a large LCD display. Intended for use with single and multiple stage heat pump units, the thermostat can control 2 reversible DX heat pump compressors, one binary reversing valve, one binary supply fan relay, plus one binary stage of auxiliary heating (gas or electric). This BASstat is BACnet compliant and BTL listed to ensure seamless integration, using BACnet/IP over Wi-Fi and can be integrated into any 802.11 b/g/n Wi-Fi network. A large, easy to read LCD display indicates setpoint, space temperature and current mode of operation using graphical icons.
The BASstat has a built-in space temperature sensor with provision for remote wired 3kΩ NTC thermistor sensor or temperature value can be sent by another communicating device over the BACnet network. The BASstat is configurable locally using the Engineering Menu or via a network connection to a BACnet client. Contemporary Controls’ free BACnet Discovery Tool (BDT) (ccontrols.com) can be used for initial configuration of the thermostat over BACnet. Control algorithm parameters such as deadband, proportional gain, integral rate and trip points are all configurable. This BASstat also features configurable fan control and occupancy selection. Operating states are indicated on the thermostat display.
The numerous features available in the BASstat can be configured by the systems integrator to meet user requirements in two different ways. One way is using a button sequence on the thermostat in order to enter the Engineering Menu – which requires physical access to the thermostat. Optionally, the buttons could be locked to limit user access to Engineering Menu after installation is complete. The second method is configuring the thermostat over the BACnet network using a BACnet client device or software such as Contemporary Controls’ free BACnet Discovery Tool (BDT) (ccontrols.com) BACnet Discovery Tool (BDT) (ccontrols.com).

3.2 Limited Power Source
The BASstat is intended to be powered by a Class 2 compliant power source and only accepts 24VAC with no more than 5VA of power consumption. It should be powered by a Class 2 power source complying with the requirements of the National Electric Code (NEC) article 725. The transformer or power supply complying with the Class 2 rating must carry a corresponding listing from a regulatory agency such as Underwriters Laboratories (UL).
3.3 Power Supply Precautions
Internally, the BASstat utilizes a half-wave rectifier and can share the same AC power source with other half-wave rectified devices. Sharing AC power with full-wave rectified devices is NOT recommended. AC power sources that power several half-wave devices have a common secondary connection called COMMON, LO, or GROUND. Connect the HOT side of the secondary to the 24 VAC high side input on the BASstat and the LO side to 24 VAC common.
WARNING: Devices powered from a common AC source could be damaged if a mix of half- wave and full-wave rectified devices are both present. If you are not sure of the type of rectifier used by another device, do not share the AC source with it.
3.4 Wiring Diagram

Operation

4.1 User Mode
User-side control is accomplished with six buttons – MODE (Heat, Cool, or Ventilate), FAN (Auto or On), UP, DOWN, SET, and POWER. There are options to lock the panel buttons to limit user access if so required. A large LCD display indicates setpoint, space temperature, occupancy status, and current mode of operation using graphical icons. System modes (Cool, Heat, Ventilate) available to the user are dependent on control type chosen from Engineering Menu (tyPE) or BACnet object [MSV7] Control Type. See section 4.2 Control Type of this manual).
System modes and button operation may be limited by installation engineer, especially if the thermostat is completely controlled over BACnet network.
The first tier of operation includes the following settings as shown below. To operate the thermostat:

1. The POWER button toggles between ON or OFF states to start / stop the thermostat outputs. (ON/OFF control can be accomplished over BACnet as well).

2. At power ON, press any button to start the User Mode operation. Press the MODE button to toggle between different HVAC operating modes such as Cool, Heat, or Ventilate@Cool and Ventilate@Heat.
   Press the UP/ DOWN buttons to adjust temperature setpoint or rotate the values of a menu setting. Press the FAN button to toggle fan modes of AUTO or CONTINUOUS On. If no AUTO icon is displayed, the fan will run continuously until commanded off using button on thermostat or BACnet command. If AUTO icon is flashing, the fan is operating under delay timer and will shut off automatically when the end of cycle delay timer expires.
   Press the SET button and use UP/ DOWN buttons to toggle the unit between Occupied or Unoccupied states when outside of scheduled operation. Use SET or MODE to apply (SET button can be locked in applications forbidding occupancy state user control).

3. Thermostat will return to normal display with the last known setting if there’s no button pressed for 10 seconds.

User Mode Flow Chart

4.2 Control Type
Control Type, System Mode and Algorithm Configuration
System modes available to the user are dependent on control type.
Multi-stage Cooling or Heating with Auto Changeover – This the default control type in this thermostat. Mostly used for standalone operation. The thermostat will switch between Cool and Heat modes automatically. In this control type, the user will be presented with a choice of Heat or Ventilation@Heat when the thermostat is in Heat mode (automatic), and Cool or Ventilation@Cool when the thermostat is in Cool mode (automatic).
Multi-stage Cooling or Heating with Manual Changeover – In this control type the thermostat will wait for a command from user or BACnet supervisor to switch between Cool and Heat modes. The user will be presented with a choice of Heat or Ventilation@Heat when the thermostat is in Heat mode, and Cool or Ventilation@Cool when the thermostat is in Cool mode. The user can choose to switch between Cool and Heat modes using the MODE button.
BACnet controlled – In this control scheme, the built-in thermostat algorithm can be bypassed, and the thermostat can be controlled over the BACnet network with commands from the supervisor device. The logic executing in the supervisor (such as Niagara or Sedona logic) can control the thermostat over the BACnet network. To put the thermostat in BACnet network control mode, use the Lock [AV18] object bit 9: Control DOs by thermostat algorithm “0” (default) or BACnet supervisor “1” (add decimal=512).
Cool Only and Heat Only modes (nullified/disabled in firmware) are control types listed in the BACnet object and Engineering Menu object but are not available for use. Control type is only configurable by the installer using Engineering Mode Menu or BACnet supervisor. The installer must decide the control type suitable for the application, set it to a static value, or program the BACnet supervisor to change the control type automatically. The default control type is set to Cooling or heating with Auto Changeover. Manual Changeover can be used to prevent excessive automatic changeover between cooling and heating system modes.
Algorithm

• A PID adaptive control algorithm is applied to minimize overshoot, in addition to proportional band (Stage Width) and derivative (Differential) calculation.
• When the thermostat is active (either the heating or cooling stage is on), a “Working ( )” icon will be shown on the LCD. Stage 1 will show icon ( ).
  Stage 2 will show icon ( ) 3rd stage heat will show icon ( ).

System Mode

• The default control type, multi-staged cooling and heating with automatic changeover, allows the thermostat to operate as stand-alone. Manual Changeover allows restriction of mode selection to Cool only or Heat only where necessary. Control Type can be selected in (tyPe) or [MSV7].
• For manual changeover control, cooling or heating system modes can be selected by pressing the MODE button or using a BACnet command to object [MSV1]. In application where user control needs to be limited, the lock button function can be used to disable MODE button.
• Occupied Cooling [AV0] and Heating [AV3] set points and Unoccupied Cooling [AV8] and Heating [AV9] setpoints can be set individually. Minimum deadband [AV7] can be programmed as well.

Short On/Off (Minimum On/Off time) and Maximum cycles per Hour

• There are short on/off (minimum off time and minimum on time of stage engagement) and maximum cycles per hour protection for cooling and heating mode(E29, E31, E54, E55; AV24, AV26, AV46, AV47).
• Short on/off time (in seconds) will check minimum on time and minimum off time of each stage before changing its state.
• Maximum cycles per hour will check cycle times in a particular hour. When the cycle times reach the setting maximum cycles in that hour, it won’t allow more cycles until next hour.
• When the stage state change is pending by Short Cycle Delay or Maximum Cycles, the Clock icon ( ) will appear on the LCD.

Next Stage Engagement Short Cycle Delay
There needs to be an automatic delay (Short Cycle, default 5 minutes, E28/ AV23 for cooling control, E30/AV25 for heating control) before starting the second stage to prevent possible damage to the DX equipment.
Reversing Valve Polarity
Reversing Valve N.O./N.C. for cooling and heating mode changeover is defined by
E53/BV3. The default setting at pin 3 (O/B) is open for cooling and closed for heating.

Floating Deadband
The Heat and Cool temperature setpoints could be “attached” together. This means that as one setpoint is adjusted and “hits” against the deadband region, it will “push” the deadband region and the other setpoint along the temperature setpoint axis to allow for adjustment while maintaining the configured deadband. If the setpoint is adjusted back the other way, it will “pull” the deadband region and the other setpoint along the temperature setpoint axis.
Minimum Cooling Setpoint and Maximum Heating Setpoint

• Minimum Cooling Setpoint will be confined by set point low limit plus dead band and Minimum cooling setpoint [AV-39] default: 18℃/ 65℉
• Maximum Heating Setpoint will be confined by set point high limit minus dead band and Maximum heating setpoint [AV-40] default: 25℃/ 77℉

Assigned Current Temperature
A current temperature value can be assigned thru BACnet AV-1 to take place of the onboard temperature sensor value. The assigned value is valid if BACnet communication is driving a flip-flop signal to (BV-16: heartbeat signal) within the (AV29: Heartbeat Rate time) period (in seconds). Otherwise, the assigned temperature will revert back to the onboard sensor reading.
Fan Control Output

• Lowest Fan Speed is the speed the fan will default to after a control action (Heating or Cooling) with fan in AUTO mode. If the lowest fan speed [MSV4] is set as “Stop (1)”, the fan will automatically shut off after the control action plus a 2-minute fan-off time delay. During this delay, the AUTO icon will flash. If lowest fan speed is set to “Low (2)” the fan will run continuously after a control action
• Fan Mode can be toggled between AUTO or ON by using the FAN button on the thermostat or BACnet object [MSV0] Fan Mode (BACnet supervisor). By default, this value is set to “Auto(1)”, the AUTO icon is displayed and fan operation will be controlled automatically. To put the fan in ON mode set [MSV0] to “Low(2)”. This will cause the fan to run continuously (no AUTO icon is displayed). Fan icon spins when fan is active. The FAN button can be locked to limit user access to this feature or the BACnet supervisor can be programmed to default the thermostat to certain state at the end of an occupancy cycle.
• During heating operations, the supply fan is controlled by the BASstat. This is enabled by default. (BV15 =1)

Occupancy Setting
There are several ways to define thermostat occupancy state.
Note: Occupancy will be detected by ESI contact by default.

• Energy Savings Input (ESI) This is a dry contact input meant for communication from a customer supplied occupancy sensor. (default)
• Occupancy status (occupied/unoccupied) can be set by a BACnet supervisor using writable object ESI Contact Definition [BV14]. “0” for occupied, and “1” for unoccupied. E12/AV18 must be set with a value of 64 (disabled) in advance (E12/AV18 is set as 0 by default)
• User control of occupancy state is allowed from the SET button if E12/ AV18 Lock has the ESI Contact disabled. Pressing the SET button and UP/DOWN buttons will toggle the occupancy state. Press SET button to confirm. The SET button can work in conjunction with BACnet occupancy Command [BV14] on last-write-wins basis. The SET button could be locked to limit user control (use Lock [AV18] BACnet object or (LOC) engineering menu item to lock SET button). In this case only the BACnet supervisor can set occupancy states.
• Occupancy Status [BI0] is a read-only BACnet object indicating current occupancy state -“0” for occupied, and “1” for unoccupied. (AV18 is set as 0 by default).
• When in unoccupied state, a Moon ( ) icon will be displayed on the LCD and the thermostat will change the set-point temperatures to the Unoccupied Cool and Unoccupied Heat setpoints [AV8 – 9]. When the state changes back to occupied, the thermostat will return to the occupied set-point values for Cooling and Heating Temperature Setpoint [AV0, AV3] and a sunlight icon ( ) will be displayed to indicate occupied state on LCD.

4.3 Engineering Mode Menu
Thermostat configuration can be performed using the engineering menu or by controlling BACnet objects using a BACnet client tool such as Contemporary Controls free BACnet Discovery Tool (BDT) (ccontrols.com). It is highly suggested that engineering mode be operated by trained installers only, because it is related to system parameters that will affect the control results.
Operation of Engineering Menu

• At power “ON”, press and hold both the UP and DOWN buttons simultaneously for 5 seconds to enter Engineering Mode menu.
• Press the UP or DOWN buttons to rotate through the menu items. The last item loops back to first item at the end of items in menu. Press the MODE button to enter a submenu item.
• Press the UP or DOWN button to change the setting in the submenu item. Press the MODE button to confirm the setting and return to menu item selection. If no button is pressed for 10 seconds, the display will return to the menu item selection. After another 10 seconds, the display will return back to User mode. Settings are not changed unless confirmed using the MODE button.
• To leave Engineering Mode, rotate till (End) menu item appears and press the MODE button. Alternately, pressing no buttons for 10 seconds will return the thermostat back to User mode.

Lock Function Setup and Examples
The 16-bit binary encoded decimal register accessed through Lock [AV17] BACnet object and LOC engineering menu item is used to enable/disable features in the thermostat. The first 10 bits are used (bit 0 ~ bit 9), bits 10~15 are reserved/unused. Bits are represented by their decimal values and are added or subtracted to toggle from “0” to “1”. Add a bit’s decimal value to toggle to “1” or subtract a bit’s decimal value to toggle to “0”. See table below.

4.4 BACnet Objects and Network Configuration
Transmission types

• Physical layer: Wi-Fi 802.11 b/g/n
• Protocol: BACnet/IP
• UDP Port Number: BAC0 (47808)
• MAC address: Wi-Fi chip MAC address found written on the back side of thermostat or in Engineering Menu item (Phy3). This can assist when multiple Wi-Fi thermostats are installed.
• Device Instance: 600001

Initial Configuration
All configuration parameters are settable through use of the buttons on thermostat by entering the Engineer Menu, or once installed on the BACnet network, configuration can also be altered using BACnet commands. Network command-based configuration can also be accomplished using a Wi-Fi enabled laptop/computer/tablet/smart phone and Contemporary Controls’ free BACnet Discovery Tool.
Wi-Fi Communication Configuration
Overview
The BAST-321HP-BW2 Wi-Fi thermostat is preconfigured with a BACnet Device Instance of 600001 and a UDP Port Number of 47808 (decimal) equivalent to BAC0 (hexadecimal).
Addressing
A unique Device Instance Number throughout the entire BACnet internetwork is required to distinguish the device from all other BACnet devices. When more than one BASstat is installed at the same time, their Device Instance Number must be configured prior to connecting to the BACnet/IP network or BACnet communication will fail due to duplicate device instances.
Device instance can be modified in Engineering Menu items (dEVH) – high bytes and (dEVL) – low bytes. Device Instance = (dEVH)*1000+(dEVL). Device Instance example: if (dEVH) is set to 4194 and (dEVL) is set to 7, Device Instance Number = 4194007. Device Instance Number can also be changed by writing to BACnet object [AV21] Device Instance once the thermostat is online. The BACnet UDP Port Number can be configured in Engineering Menu item (UdP).
The BAST-321HP-BW2 will initially boot up as a Wi-Fi Access Point to allow for IP configuration. This requires connecting to the thermostat as an access point for initial configuration using a Wi-Fi enabled laptop/computer/tablet/smart phone. Look for the BAST-321HP-BW2 with its unique SSID of “WiFi-623B-xxxx” and no access point passphrase by default (simply click to connect to Access Point). The digits “xxxx” in “623Cxxxx” are the last 4 digits of the thermostat’s Wi-Fi chip MAC address found written on the back side of the Wi-Fi module.
This ensures a unique SSID for discovery and configuration and it can assist in identification of thermostats when multiple Wi-Fi stats are installed on the same site (unique identifier outlined in blue in the image below). This unique identifier can also be viewed in Engineering Menu item (Phy3). Once connected to the thermostat as an access point, open its web page by typing its default address of 192.168.0.1 with admin for username and no password. Web page pictured below will be presented for IP Network Configuration. The default IP configuration is shown below.After initial connection using laptop or tablet or smart phone, the Wi-Fi mode in the thermostat can be changed to Infrastructure mode. The local Wi-Fi router/access point  can be selected from the Available AP drop-down list, or an AP SSID can be entered manually. Enter the AP Passphrase to authenticate and connect to the AP. ATTENTION: Once connected to the Wi-Fi access point, the Wi-Fi thermostat will use the Wi-Fi access point credentials. To ensure a secure connection, when setting up the Wi-Fi router (Access Point) the thermostats will be connected to, make sure you set up a strong access point passphrase (password) and encryption method! This is required for Wi-Fi client devices to connect to the Wi-Fi router securely and it is essential to cyber security. Creating a good Wi-Fi password is the first step in creating a secure environment that is inaccessible to unauthorized parties. Use the following tips when creating a Wi-Fi access point passphrase:

• Passphrase should be a minimum of eight characters (maximum 15 characters), the more random the better. Use a mix of letters (uppercase and lowercase), numbers, and symbols.
• Do not reuse or repeat passwords across router installations or job sites.
• Change WiFi password regularly (not required but very secure). Provides guidelines for building maintenance personnel.
• Disable broadcast of SSID. This is a very simple setting which stops the broadcast of the access point SSID, and only authorized parties who know the SSID can connect to it. This is configured in the Wi-Fi router.
• Store passwords in a safe place, limit access to authorized parties only, and provide instructions for password reset and reconfiguring a strong password in cases of reconfiguring the network in the future.

Choose an option for DHCP addressing using the radio buttons. The thermostat supports DHCP addressing and will acquire an IP address from the router/access point automatically if you chose Enable next to DHCP. If you chose Disable, you must assign an IP Address, Network Mask, and Gateway Address within the Wi-Fi router IP subnet manually. A reboot of the thermostat is required for new IP configuration to take effect. Click the Save & Restart button to reboot the thermostat, and you will be prompted to confirm the restart. Click OK to Save New Settings and Restart or click Cancel to revisit IP configuration. When OK is clicked, a confirmation is displayed to indicate configuration is stored in the thermostat’s internal memory. After reboot, the new thermostat credentials will be admin for username and the newly configured Access Point’s password for password. Click OK on the confirmation message and wait 20 seconds for the reboot process to complete.While rebooting, the thermostat will display “DP” icon in the lower right corner to indicate it is in the process of searching and connecting to the AP. Once the “DP” stops flashing, the thermostat has successfully connected to Wi-Fi access point. After reboot of the thermostat, the new Infrastructure mode with new IP settings will be used. The thermostat is now connected to the local Wi-Fi network AP selected in configuration screen and will not show up as an access point itself any longer. If you are unsure of the thermostat’s IP address, it could be viewed through the Engineering Menu in items (IP-1) for the first octet, (IP-2) for the second octet, (IP-3) for the third, and (IP-4) for the fourth octet of the IP address, or if you have access to the Wi-Fi access point, its “statistics” or “connected devices” web page will show the BASstat BW2’s IP address as well as MAC address (the same address in Engineering Menu items Phy1, Phy2, and Phy3 and the printed MAC on the back of the thermostat Wi-Fi module (outlined in blue above).
Reset Settings
The BASstat will store configuration in the event of power loss. If configuration fails or the thermostat needs to be configured to use a different Wi-Fi access point, the thermostat must be reset and reconfigured. There are 2 reset settings options for the Wi-Fi thermostat:

• Boot will restore Wi-Fi communication parameters to default, but it will maintain control algorithm settings. Select (boot) engineering menu item and press MODE to confirm.
• Reset will restore all values to default and can be selected from engineering menu (rSt).

Foreign Device Registration (FDR)

Communication across IP subnets requires a Broadcast Management Device (BBMD) device or support for Foreign Device Registration (FDR) feature. The BASstat supports the FDR feature to register with a remote BBMD which could be a BACnet client or a BMS headend. To communicate with BACnet clients across subnets, the BAST321HP-BW2 can do FDR registration with a remote BBMD. The BACnet BBMD feature requires a BACnet device with BBMD capability, such as a BACnet router or other, to be installed and configured on the network. BBMD allows discovery of all BACnet/IP devices in the IP subnet instead of just the FDR device.

• Select As Foreign Device.
• The BBMD IP is the address of the BBMD device on the remote network. Enter the address of the BBMD with which the BAST-321HP-BW2 will perform Foreign Device Registration (FDR) if there is no local BBMD device in the same subnet as the BAST321HP-BW2 providing communication to the remote subnet.
• Enter the UDP port for BBMD.
• Time to Live is the BBMD registration time. Specify the seconds between successive FDR registrations. Recommended value is 100.

A reboot of the thermostat is required for new IP configuration to take effect. Click the Save & Restart button to reboot the thermostat, and you will be prompted to confirm the restart. Click OK to Save New Settings and Restart or click Cancel to revisit IP configuration. When OK is clicked, a confirmation is displayed to indicate configuration is stored in the thermostat’s EEPROM. After reboot, the new thermostat credentials will be admin for username and the newly configured Access Point’s password for password.
Click OK on the confirmation message and wait 20 seconds for the reboot process to complete.

Warranty

Contemporary Controls (CC) warrants this product to the original purchaser for two years from the product shipping date. Product returned to CC for repair is warranted for one year from the date the repaired product is shipped back to the purchaser or for the remainder of the original warranty period, whichever is longer.
If the product fails to operate in compliance with its specification during the warranty period, CC will, at its option, repair or replace the product at no charge. The customer is, however, responsible for shipping the product; CC assumes no responsibility for the product until it is received.
CC’s limited warranty covers products only as delivered and does not cover repair of products that have been damaged by abuse, accident, disaster, misuse, or incorrect installation. User modification may void the warranty if the product is damaged by the modification, in which case this warranty does not cover repair or replacement.
This warranty in no way warrants suitability of the product for any specific application. IN NO EVENT WILL CC BE LIABLE FOR ANY DAMAGES INCLUDING LOST PROFITS, LOST SAVINGS, OR OTHER INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PRODUCT EVEN IF CC HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR ANY CLAIM BY ANY PARTY OTHER THAN THE PURCHASER.
THE ABOVE WARRANTY IS IN LIEU OF ANY AND ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED OR STATUTORY, INCLUDING THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR PARTICULAR PURPOSE OR USE, TITLE AND NONINFRINGEMENT.
