Functions
If the room temperature falls below the selected setpoint, the heating contact will close.
If the room temperature exceeds the selected setpoint, the cooling contact will close.
There are two possibilities to control the fan speed:
a) Manually by means of the three - speed fan switch on the thermostat for continuous
operation
b) Automatically by switching to the selected fan speed via the thermostat for
controlled operation. In that case – prior to commissioning – the jumper positions
corresponding to the thermostat function must be selected. There are two choices of
jumper positions available on printed circuit board:
SR1
SR2
Selected fan speed as continuous operation
Auto Fan is switched at the same time as the cooling or
heating valve, depending on the switch position.
When the ventilation function is selected (RAB31.1) on the cover by setting the slide
switch, the heating and cooling contacts are always open and the fan operates at the
selected speed.
Heating or cooling is selected with a switch located on the front of the thermostat.
