The “thermio™ eco C3” thermostat is used to regulate three heating circuits. Hot water or heating cir-
cuits can be connected and regulated independently of each other. Individual regulation of, for example,
two independent heating zones (living and sleeping areas) and hot water is implemented using three
independent switching outputs.
In the standard method, the water or room temperature is regulated by switching the device on and off
for periods of time. The on and off times for these periods can be programmed individually. In addition,
you can set a setpoint for the room temperature if the temperature regulation function is activated. An
additional frost protection function protects the device or the connected pipelines against frost when the
device is switched off.
