Nominal room temperature setpoint
In nominal operation, the nominal room temperature setpoint is maintained.
The nominal room temperature setpoint is adjusted with the knob for the nominal
temperature, which is located on the controller front for direct access by the user.
When turning the knob, the current room temperature setpoint is displayed and – when
turning further – readjusted. The value applies to both heating circuits.

• Readjustment of the nominal setpoint with the knob can be locked via OEM

• Minimum and maximum limitation of the nominal setpoint setting range can be
accomplished via OEM parameters 100 and 101
When the nominal room temperature setpoint is active, the rooms will be heated
according to the adjustment made with the setpoint knob.
The adjustment made with the knob is only active in automatic and continuous
operation.
The nominal phases depend on the settings made on lines 11 through 16 for heating
circuit 1 and according to the settings made on lines 21 through 26 for heating circuit 2.
