|
setpoint of economy mode is the same in automatic and continuous operation. |
||
Protective function |
In the frost or overtemperature protection mode, the room temperature is constantly |

|
monitored. If it falls (rises) below (above) the adjusted setpoint, heating / cooling is |
||
|
switched on to maintain the adjusted frost or overtemperature protection setpoint tem- |
