Unlike ordinary single unit design thermostat, this unit is a new type of thermostat separating

the thermostat function into two units. The Receiver serves for wiring connections and

heat/cool on/off control. The Control Centre serves as user interface

and temperature sensing/control. The two units are linked by RF.

The advantage is that user can put the Control Centre nearby and can read/control the

temperature of really the living area.

5. TEMPERATURE SPAN SELECTION Span is the temperature difference between the turn on temperature and turn off temperature. For example, in heating systems, if you set temperature to 20°C and span to 1°C, the heater will operate when the room temperature drops to 19.5°C and turns off when the temperature rises to 20.5°C. Set the DIP switch (position 1 & 2) according to your selection of temperature span as the following diagram. 1 2 Span ON ON 1°C OFF ON 2°C ON OFF 3°C OFF OFF 4°C 6.
