Page 2 The SRT323 will only operate when 2 x AAA batteries have been fitted. This document provides information specific to the Z- wave technology implemented on SRT323, to ensure interoperability with third party devices.
Page 3 USER INSTRUCTIONS The Secure SRT323 thermostat uses the latest control technology to provide extremely accurate temperature control which will help to keep your energy usage as low as possible without affecting your comfort levels. In fact comfort levels may well be improved as the control accuracy should ensure that the room does not ‘overheat’...
Page 4 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’...
Page 5 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...
Page 6 Battery Replacement The SRT323 runs on 2 x type AAA (alkaline) non rechargeable batteries and is designed to give a battery life of approximately two years – under normal usage conditions. Battery should When the batteries are be changed nearing the end of their life...
Page 7 Remove the old batteries and replace them with two new AAA size alkaline batteries ensuring that they are fitted correctly as indicated by the terminal markings in the battery compartments. Once the batteries are fitted, re-fit the thermostat to the wall plate by engaging with the lugs at the top of the wall plate and push the thermostat into position.
Page 8 INSTALLER INSTRUCTIONS 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.
Page 9 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.

Page 12 Avoid installing the thermostat against or behind any large metal surfaces which could interfere with the radio signals. The SRT323 should be mounted on an internal wall approximately 1.5 metres from floor level using the wall plate provided and should be in a position away from draughts, direct heat and sunlight.
Page 13 Fitting the Wall Plate 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.
Page 14 Wiring Guide SRT323 Thermostat – Internal Wiring Diagram The S RT323 is double insulated and does not require an earth connection, an earth connection block is provided on the wall plate for terminating any cable earth conductors. Earth continuity must be maintained and all bare earth conductors must be sleeved.
