  • Page 2: Quick Start

    Product Description The SRT321 is a battery operated wall thermostat. Using a big wheel on the device the user can preset the desired target temperature in the room. By verifying the target temperature with the measured real temperature closed to the device the unit decides how to operate a wirelessly attached power switch that is attached to the heater.

  • Page 3: Installation

    Installation Choose a suitable mounting position in your room for installing the device. The SRT321 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 4 Offer the plate to the wall in the position where the SRT321 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 5: Product Usage

    Product Usage 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.

    C (Primary Shift) This function allows the installer to manually relinquish the primary  controller role of the SRT321 to become a secondary or inclusion controller Node Information Frame The Node Information Frame (NIF) is the business card of a Z-Wave device. It contains information about the device type and the technical capabilities.
  • Page 7 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.

    Attention: Removing a device from the network means that it is turned back into factory default status. This process can also exclude devices from it's previous network. For Exclusion of Z-Wave devices from the thermostats network do the following steps: Set DIL switch 1 on the back of the unit to "ON"...
