Installation
1. IMPORTANT: ensure all electrical connections are isolated before commencing any work on the
unit.
2. Unscrew and remove the front of the enclosure which contains the electronics.
3. Mount the rear of the enclosure to the wall using the 4 pre-existing screw points. DO NOT drill
through the back of the enclosure as this will void the product IP rating.
4. Ensure best-practices are used when choosing a location for the thermostat so that optimal
thermostatic control is achieved. Do not mount near drafts, heaters, radiators, air conditioners, in
direct sunlight or any other place where the sensed temperature may be unnaturally inuenced. A
good mounting height is typically between 1m and 2m from the oor.
5. Pass the electrical cable through the cable gland then connect as shown in Figure 1 (or any suitably
appropriate form). Ensure the correct output terminals that are suitable to your application are
chosen.
6. Adjust the internal thumbwheels to suit the desired operational requirements (see below).
7. Screw the front of the enclosure back on then tighten the cable gland to seal against the cable.
Operation
1. IMPORTANT: ensure all electrical connections are isolated before commencing any work on the
unit.
2. Adjust the “Setpoint” dial to the temperature the area is to be regulated to (typically 20ºC).
3. Set the “Dierential” to the total temperature swing either side of the resulting setpoint that the
temperature is required to keep within (typically 1°C).
4. Example set-up:
Setpoint set to 20ºC, Dierential set to 1ºC.
The thermostat will maintain the temperature between 19.5ºC and 20.5ºC.
