What is Z-Wave?

Z-Wave is the international wireless protocol for communication in the Smart Home. This
device is suited for use in the region mentioned in the Quickstart section.

Z-Wave ensures a reliable communication by reconfirming every message ( two- way
communication) and every mains powered node can act as a repeater for other nodes
( meshed network ) in case the receiver is not in direct wireless range of the
transmitter.

This device and every other certified Z-Wave device can be used together with any other
certified Z-Wave device regardless of brand and origin as long as both are suited for the
same frequency range.

If a device supports secure communication it will communicate with other devices
secure as long as this device provides the same or a higher level of security.
Otherwise it will automatically turn into a lower level of security to maintain
backward compatibility.

Product Description

The SRT323 is another device from the SRT Z-Wave room temperature series which own latest Technology regarding energy saving and remote control. SRT323 is a single-box solution with integrated relay that includes time-proportional integral (TPI) software and interoperable Z-Wave radio. It can be used as a direct replacement for existing thermostats without the need for wiring changes, while the TPI software optimises boiler firing to help maintain the set temperature without “overshooting”. It has been shown that TPI controllers can provide considerable energy savings compared with traditional heating controllers. The interoperable Z-Wave radio enables you to remotely change the set point, read the temperature or receive alerts. SRT323 is an ideal partner for use with a Z-Wave smart home gateway. Web-enabled apps allow remotely heating control from outside home. You don”t have to worry about returning to a cold home anymore.

Prepare for Installation / Reset

Please read the user manual before installing the product.

In order to include (add) a Z-Wave device to a network it must be in factory default
state. Please make sure to reset the device into factory default. You can do this by
performing an Exclusion operation as described below in the manual. Every Z-Wave
controller is able to perform this operation however it is recommended to use the primary
controller of the previous network to make sure the very device is excluded properly
from this network.

Installation

DIL switch settings

On the rear of the unit in the center there are DIL switches that control TPI and installation mode as described below.

TPI temperature control software Thermostats, using TPI (Time Proportional Integral) control algorithms, will reduce the temperature swing that normally occurs when using traditional bellows or thermally operated thermostats. As a consequence, a TPI regulating thermostat will maintain the comfort level far more efficiently than any traditional thermostat.

When used with a condensing boiler, the TPI thermostat will help to save energy as the control algorithm allows the boiler to operate in condensing mode more consistently compared to older types of thermostat.

1. DIL switch numbers 2 and 3 should be set as diagram opposite.
2. For Gas boilers set the TPI setting to 6 cycles per hour. (Default setting)
3. For Oil boilers set the TPI setting to 3 cycles per hour.
4. For Electric heating set the TPI setting to 12 cycles per hour.

Offer the plate to the wall in the position where the SRT323 is to be mounted and mark the fixing positions through the slots in the wall plate. Drill and plug the wall, then secure the plate into position. The slots in the wall plate will compensate for any misalignment of the fixings. Connect the wires in accordance with the wiring diagrams and fit the terminal covers. Complete the installation by swinging the room thermostat into position by engaging with the lugs at the top of the wall plate before pushing it carefully into its plug-in terminal block. Tighten the 2 captive screws on the underside of the unit.

Inclusion/Exclusion

On factory default the device does not belong to any Z-Wave network. The device needs
to be added to an existing wireless network to communicate with the devices of this network.
This process is called Inclusion.

Devices can also be removed from a network. This process is called Exclusion.
Both processes are initiated by the primary controller of the Z-Wave network. This
controller is turned into exclusion respective inclusion mode. Inclusion and Exclusion is
then performed doing a special manual action right on the device.

Inclusion

Please refer to the 3rd party manufacturers instructions of the Z-Wave controller or gateway that will be used in conjunction with the SRT323 to determine how to add the SRT323 to that controller/gateway. Set DIL switch 1 to “ON” position on the back of the unit, scroll through the function menu by rotating the dial. To select the required function (L) press the dial. On selecting the function the character will start flashing while waiting for a response from the 3rd party device, a successful response will display a P after the character and a failure will be displayed with an F. If no response has been received from a 3rd party unit within the time-out period, the SRT323 will report a failure.

Exclusion

Please refer to the 3rd party manufacturers instructions of the Z-Wave controller or gateway that will be used in conjunction with the SRT323 to determine how to add the SRT323 to that controller/gateway. Set DIL switch 1 to “ON” position on the back of the unit, scroll through the function menu by rotating the dial. To select the required function (L) press the dial. On selecting the function the character will start flashing while waiting for a response from the 3rd party device, a successful response will display a P after the character and a failure will be displayed with an F. If no response has been received from a 3rd party unit within the time-out period, the SRT323 will report a failure.

Product Usage

The display will show the required temperature setting and can be adjusted in increments of 1″°C. To adjust the required temperature setting, turn the dial anticlockwise to decrease it and clockwise to increase it. The thermostat may be operated as an ordinary wired thermostat with no radio connection necessary. In this condition no radio wave symbol is displayed. In the following description, it is assumed that the thermostat has been incorporated into a Z-Wave system. When the thermostat is in the “call for heat”condition a flame symbol will appear in the display. Pressing the temperature setting dial will allow the user to check the current actual measured room temperature which will be displayed for approximately 7 seconds before returning to the set temperature. The aerial symbol complete with radio wave symbols in the display of the SRT323 thermostat indicates that it is wirelessly communicating with the rest of the system. If the SRT323 is connected to a wider wireless system, a flashing radio wave would indicate a loss of communication. This may be temporary and can often be restored by turning the thermostat dial and increasing or decreasing the temperature to make the thermostat send a temperature update to a controller.

Quick trouble shooting

Here are a few hints for network installation if things dont work as expected.

1. Make sure a device is in factory reset state before including. In doubt exclude before include.
2. If inclusion still fails, check if both devices use the same frequency.
3. Remove all dead devices from associations. Otherwise you will see severe delays.
4. Never use sleeping battery devices without a central controller.
5. Dont poll FLIRS devices.
6. Make sure to have enough mains powered device to benefit from the meshing

Association – one device controls an other device

Z-Wave devices control other Z-Wave devices. The relationship between one device
controlling another device is called association. In order to control a different
device, the controlling device needs to maintain a list of devices that will receive
controlling commands. These lists are called association groups and they are always
related to certain events (e.g. button pressed, sensor triggers, …). In case
the event happens all devices stored in the respective association group will
receive the same wireless command wireless command, typically a ‘Basic Set’ Command.
