temperature by 4°C.
To make use of the set-back function, a 230v time clock is also required on the system.
Place the thermostat slide switch into the time clock position.
When the thermostat receives a 230v signal from the time clock it will control the
temperature according to the dial setting.
When no 230v signal is received from the time clock, the thermostat will operate in
setback mode and automatically reducing the set temperature by 4°C
Right LED
The right LED is the power LED. It is a two colour LED and is used to indicate the
time clock / set-back status.
Left LED
The left LED indicates the heating status. It illuminates when the thermostat is
calling for heat.
The time clock can be bypassed by placing the switch into position 1.
In this position, the thermostat will ignore the time clock input and will continuously
control to the set temperature. This feature can be used to extend the heating period
without the need to adjust the time clock program.
