Stuhl SF29, thermostat 24Vac

Description

Application
The SF29 T electronic room thermostat is intended for room temperature dependent
control of heating installations in dry environment with limitation and possibility to connect external sensor. (included in packaging)

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.
