ntroduction
T
he thermostat is capable of switching on your heating system at pre determined times on different days of the week. It is possible to set 4 periods called
events each day with different temperatures. From factory a default schedule is programmed suitable for most installations. Unless you change these
s
ettings the thermostat will operate to this default program.
Working with lower temperatures during times that the room is unoccupied will lower your energy costs without reducing the comfort. The thermostat has an
adaptive function that automatically changes the start time of a heating period so that the desired temperature is reached at the time that you set. After 3
d
ays the adaptive function has learned when the heating must be switched on.
The thermostat has a built-in temperature sensor and an externally temperature sensor. In this configuration the thermostat controls the temperature within
the room and use the externally temperature sensor as limit sensor avoiding too high or too low temperatures in the floor construction.
T
he thermostat has a pin button marked R, allowing you to reset the thermostat to factory settings. These are listed at the end of this manual with space for
you to record your own weekly schedule.
T
he display is backlit when operating the buttons. The heating element is switched off when the light is on in the display.
The heating system can be switched off on the built-in interrupter. The Microprocessor taking care of the time will still be supplied with power whereby time
a
nd day will be maintained. When the heating is required and the thermostat is switched on, it will continue the 4-event programme based on present time
a
nd day.
