Siemens Room Thermostat RAB10... CE1N3011en
Building Technologies 25.02.2008
There are 2 possibilities to control the fan speed:
a) Manually by means of the thermostat’s 3-speed fan switch for continuous operation
(RAB10 and RAB10.1).
b) Automatically by switching to the selected fan speed via the thermostat for con-
trolled operation. In that case – prior to commissioning – the jumper position corre-
sponding to the thermostat function must be selected . There are 2 choices of
jumper positions available on the printed circuit boards of the RAB10 and RAB10.1.
Jumper SR1
Jumper SR2
Selected fan speed as continuous operation
Auto
Fan is switched at the same time as the valve
Note on RAB10.2:
In heating mode, the fan is released together with the control out-
put (Y) and depending on the water temperature acquired by the aquastat. This
means that, for switching on the fan, the room temperature must lie below the se-
lected setpoint and the aquastat contact must have closed. In cooling mode, the fan
is released with the control output (Y).
When the ventilation function
is selected (RAB10.1) with the slide switch on the unit
front, the heating and cooling contacts are always open and the fan operates at the
selected speed.
Heating or cooling mode is selected with the switch located on the unit front (RAB10...).
