Installers manual

INTRODUCTION

Heatit Z-Temp3 is a battery-operated thermostat designed for controlling waterbased heating systems. Used in combination with the Heatit Z-Water2, you can control your heating system through the Z-Wave network or via the buttons on the front panel. The thermostat has a user-friendly interface. ® Heatit Z-Temp3 has 3 modes: Heat, Cool, and Eco. The thermostat fits into System 55 frames, and may be mounted alongside other equipment such as e.g dimmers or light switches. Heatit Z-Temp3 can also be mounted directly on the wall or placed freely, e.g. on a shelf.
Heatit Z-Temp3 can be set as a master thermostat. This means that you can set the setpoint and mode on one unit, and it will automatically send the setpoint and mode to other connected units.
All communication between Heatit Z-Temp3 and the controlled device is 100% wireless.
Heatit Z-Temp3 uses 2x AAA batteries, but you can also connect the device to an external power source. The Heatit Transformer 230VAC (45 126 48) is recommended for this purpose.
Heatit Z-Temp3 can be associated with Heatit ZM Single Relay, other Z-Wave relays, Heatit ZM Thermostat, Heatit Z-TRM6 Thermostat and other Z-Wave devices to control other types of heating solutions.
Heatit Z-Temp3 is a great choice for the restoration or renovation of existing buildings, as it is easy to install without the need for wiring. We recommend using multiple 230VAC devices to create a mesh network.

STATEMENT REGARDING PRODUCTS FROM MULTIPLE MANUFACTURERS

Please read this before installation
This device may be used with all devices certified with the Z-Wave Plus ® certificate and should be compatible with such devices produced by any manufacturer. Every primary controller is different depending on the manufacturer, their
target audience and intended use/application. Please review the functionalities implemented by the primary controller you intend to use with our Z-Wave Plus certified device to ensure that it provides the necessary controls to take full advantage of our product’s capabilities.

BEHAVIOR WITHIN THE Z-WAVE NETWORK

This device may be operated within any Z-Wave network with Z-Wave-certified devices from other manufacturers. All non-battery-operated nodes within the network will act as repeaters regardless of manufacturer to increase the reliability of the network. On delivery, the device does not belong to any Z-Wave network. The device needs to be added to an existing network to communicate with the other devices within it. Devices may also be removed from a network. The add/ ® remove processes are initiated by the primary controller of the Z-Wave network.

QUICK START

1. Insert the batteries or alternatively connect the cable supplied with the Heatit Transformer 230VAC (Art. no. 45 126 48).
2. Mount the device directly on the wall or on a junction box.

The thermostat offers versatile installation options, allowing it to be mounted on a wall, on a junction box or placed at a preferred location. For wall mounting, attach the mounting plate using either screws or double-sided tape. If mounting on a junction box, use screws. Once the mounting plate is in place, carefully push the thermostat back onto the mounting plate.
NB! Be careful when installing the batteries, ensuring their polarity matches the indented markings on the plastic.

ADD/REMOVE

Please read this before installation
The primary controller/gateway has a mode for adding or removing devices. Please refer to your primary controller manual on how to set the primary controller in add/remove mode. The device may only be added or removed from the network if the primary controller is in add/remove mode. When the device is removed from the network, it will NOT revert to factory settings. Adding the device within a 2 meter range from the gateway can minimize faults during the Interview process.
Note: The Heatit Z-Temp3 does not stay in Learn mode until it is included.
There are two ways to add the device to a Z-Wave network.
7.1 Method 1: Standard (Manual)
Add/remove mode is indicated on the device by rotating LCD segments on the display. It indicates this for 90 seconds until a timeout occurs, or until the device has been added to/ removed from the network. Configuration mode can also be cancelled by performing the same procedure used for starting
Configuration mode.

1. Hold the Center button for 5 seconds. The display will show “OFF”.
2. Press the ”+” button once to see “CON” in the display.
3. Start the add/remove device process in your primary controller.
4. Start the configuration mode on the thermostat by holding the Center button for approximately 2 seconds.
   The device is now ready for use with default settings.
   NB! When the device is removed from the gateway, the parameters are not reset. To reset the parameters, see Chapter ”Factory reset”. If inclusion fails, please perform a ”remove device” process and try again. If inclusion fails again, please see “Factory reset”.

7.2 Method 2: SmartStart (Automatic)
SmartStart enabled products may be added to a Z-Wave network by scanning the Z-Wave QR-Code on the product if your primary controller supports SmartStart inclusion. No further action is required and the SmartStart product will be added automatically after being powered on within range of the primary controller.

FACTORY RESET

Enter the menu by holding the Center button for about 5 seconds, navigate in the menu with the ”+” button til you see FACT. Press the Center button until you see “– –” blinking in the display, then hold for about 5 seconds to perform a reset. You may also initiate a reset by holding the Right and Center buttons for 55 seconds.
When either of these procedures has been performed, the thermostat will perform a complete factory reset. The device will display “RES” for 5 seconds while performing a factory reset. When “RES” is no longer displayed, the thermostat has been reset. Please use this procedure only when the primary controller is missing or otherwise inoperable.

STARTUP

After powering up the device for the first time, all parameters will have default settings.

PRINCIPLES OF REGULATION

The thermostat uses temperature readings retrieved from the internal sensor to regulate the temperature. The thermostat will regulate the temperature using hysteresis or PWM, based on the setpoint temperature.
To select either “HYST” or “PWM” you can find the “REG” menu option or use Parameter 5 “Regulation mode.
10.1 Hysteresis
Hysteresis will turn on and off the load based on the hysteresis value in comparison to the setpoint. You can make changes to the thermostat hysteresis. You may choose hysteresis values between 0.3°C and 3.0°C using Parameter 7. The default setting is 0.5°C. When using waterbased heating we recommend a hysteresis of 1.0°C.
You may also change the hysteresis by entering the local settings menu and holding the Center button for 2 seconds when “REG” is displayed. Here you can choose values between 0.3 and 3.0.
10.2 Pulse-width modulation PWM
With PWM regulation enabled, the thermostat will regulate based on duty cycles. The thermostat is turned on and off in percentage intervals of the cycle. The amount of time the relay will be on is based on how far the measured temperature is from the setpoint.

LOCAL SETTINGS MENU

To enter the settings menu, hold the Center button for 5 seconds. The display will display “OFF”. You are now in the settings menu. While in the settings menu, “SET” will be displayed in the bottom right of the display. You can now scroll up and down using the Left and Right buttons. Some options have submenus. To navigate the submenus, press the Center button once to enter or exit the submenu. Press the Left and Right buttons to find your desired value and hold the Center button for 2 seconds to confirm your selection. “STOR” will appear to indicate settings are stored.

DISPLAY MENU STRUCTURE

See flowchart at the end of this manual.

TEMPERATURE SHOWN IN DISPLAY

By default, the temperature shown on the display while in standby state is the setpoint. This may be altered with Parameter 8:”Temperature display”. It may also be changed by entering the local settings menu and holding the Center button for 2 seconds when “MODE” is displayed. You can choose between “SETT” and “RELT”. “SETT” is the Setpoint temperature and “RELT” is the real-time temperature.

STANDBY AND MAIN SCREEN

When the thermostat remains untouched for a while, it will automatically go to the standby screen. The standby will by default show the setpoint temperature.
By pressing any button once, you will see the measured temperature. By pressing the Left or Right button multiple times, you will change the setpoint.

CALIBRATION

If the temperature sensor readout is not correct, you can make minor changes to the temperature readout. The temperature readings can be calibrated by ±6°C using Parameter 4.
The calibration can also be performed from the menu using CAR. The adjusted value will be displayed in the controller/ gateway indicating what the thermostat uses for regulation.

BRIGHTNESS

Using the menu choice “BR1”, the brightness of the display in Active state can be changed. “BR1” is also included in the device as Parameter 9 (BR1).

DISPLAY ON/OFF (DON/DOFF)

The thermostat has a display ON/OFF function which decides whether the display should turn completely off when in Standby. To enable/disable this function, hold the Left and Center buttons for 10 seconds. The display will show “DOFF” when the function is activated and “DON” when the function is disabled. When operating any button, the display will light up.

DISPLAY ICONS

either Heating or Eco mode.
| This icon will be displayed while the relay is on and the thermostat is in Cooling mode.
| This icon shows the current signal strength.
| This icon shows the battery status.

CHILD LOCK

The child lock function disables the buttons on the display, preventing local access and operation. It will show “LOCK” when attempting to operate it while the function is enabled. To enable or disable the function, hold the Left and Right buttons for 10 seconds. Enabling the function will show “LOCK” in the display, disabling the function will show “OPEN”.

OPEN WINDOW DETECTION OWD

Open Window Detection (OWD) is a function which will reduce the thermostat setpoint on detection of an open window. This happens when the temperature sensor registers a rapid temperature drop.
When OWD is active, the setpoint is reduced to 5°C in order not to waste energy. OWD will automatically be cancelled if OWD has been active for more than 1 hour, or if the temperature increases by 3°C. OWD can also be cancelled manually by increasing/decreasing the setpoint with the Left and Right buttons. By default, OWD is not enabled. The feature may be enabled by selecting “OWD” from the menu. Choose between options “OFF” and “ON”. It can also be enabled by setting Parameter 18 (Open window detection) to 1.

ERROR CODES

Err Adding fail. See Chapter 7 “Add/remove”.
Err1 Internal error. Most probably a faulty unit. Contact support.
Err2 Z-Wave error. Most probably a faulty unit. Contact support.
Err3 Internal error. Most probably a faulty unit. Contact support.

QR-CODE PLACEMENT (DSK)

The QR-Code is needed when including a device using S2 security or SmartStart. The DSK can be found in the QR-Code and is located;

• On the product.
• In the Quick Guide.
• On the packaging box/gift box.

SECURITY

S2 security enhances Z-Wave Plus with an additional layer of AES 128-bit encryption of the wireless Z-Wave communication to prevent hacking and man-in- middle attacks on the home network.
This device supports S2 and has a Z-Wave DSK QR-Code label that may be used when the device is added to the Z-Wave home network. The primary controller will ask for a 5-digit code. They are the first underlined 5 digits located on the
QR code sticker. The primary controller will then ask you to confirm the rest of the code that is contained in the QR-Code.

NODE INFORMATION FRAME

The node information frame is the ”business card” of a Z-Wave device. It contains information about the device type and its technical features. The add and remove procedure of the device is confirmed by sending out a node information frame. Besides this, it may be necessary for certain network operations to send out a node information frame.

ASSOCIATIONS

Z-Wave devices interact with other Z-Wave devices. The relationship between one device controlling another device is called an association. In order to control a subordinate device, the controlling device needs to maintain a list of devices that will receive controlling commands. These lists are called ”Association Groups”. They are always related to the specific event triggered (e.g., sensor reports). In case the event is triggered, all devices stored in the respective association group will receive a joint wireless command.
25.1 Setting and Removing Associations
Associations may be assigned and removed via Z-Wave commands. Please refer to your primary controller/Z-Wave gateway for more information.

ASSOCIATION GROUPS

Lifeline Group to be used by primary controller, sends:
– Thermostat Operating State
– Thermostat Setpoint Report
– Thermostat Mode Report
– Sensor multilevel Report
– Device Reset Locally
– Battery Report
– Protection Report
– Configuration Report
Max nodes in group: 1
Group 2| Binary Switch Set.
Send Binary Switch set commands based on the internal relay state, sends:
-Binary Switch Set
Max nodes in group: 10
Group 3| Binary Switch Set.
Send Binary Switch set commands based on the internal relay state, sends:
-Binary Switch Set
Max nodes in group: 10
Group 4| Thermostat Mode set.
Sends Thermostat Mode set commands based on own mode to allow for use as master thermostat, sends:
-Thermostat Mode Set
Max nodes in group: 10

If the thermostat is to control a relay, an association from Group 2 must be created from the thermostat to the relay that is to be controlled.
Disclaimer: When using the Heatit Z-Temp3 to control multiple relays on a Heatit Z-Water (Art. no. 4512475) or a Heatit Z-Water2 (Art. no. 4512495), only use relays 1 through 7. Do not use relays 8, 9, or 10 for this purpose. If the thermostat is to control other thermostats as a master thermostat, an association from Group 3 and Group 4 must be created from the master thermostat to the thermostats to be controlled.
