Stuhl SF20, thermostat 24Vac for heating

Description

Application
The electronic room thermostat SF20 T is intended for the room temperature dependent
control of heating installations in dry environment.

Characteristics
The room temperature is measured with the internal sensor.
By means of the rotary knob sets the desired room temperature between 5'C and 30'C. The energy demand is indicated with the light-emitting diode.

To heat
In heating mode, the output is activated when the room temperature is below
the set value comes.
