Function switch:
Automatic mode (I)
When the automatic mode is switched on, the heating coil, in accordance with the set bivalence point or the
building heating load and selected inlet temperature, is engaged after a time lag and assists the heat pump
in parallel operating mode.
Manual operation (II)
When manual mode is engaged, the heating coil is engaged directly, regardless of the parameters in the
Smart Control. This function can be used in the emergency heating mode, or for the pre-heating of non-
installed or operationally capable outdoor modules. The temperature is then set using the thermostat on the
housing.
LED red (On):
This LED indicates if the heating coil is being activated or not.
Reset STB (Reset):
If the overheating of the heating coil has triggered the safety temperature limiter (STL), it can be reset after
cooling down again by pressing this button. However, the reason for it being triggered must be analysed and
remedied.
