If this button is pressed and held longer than 5 s in the basic display, the controller is switched to manual mode. In this operating mode, the required heat generator temperature is specified manually with the input button î according to the respective heating need.

A controller set to manual mode has no effect in heat circuit expansion.

The heat generator setpoint is set between the minimum and maximum heat generator temperatures and appears flashing at the bottom left-hand side. The current heat generator temperature appears statically on the right-hand side in the basic display. The set switching differential corresponds to the value of automatic control and is symmetrical to the set value.

Application Controller malfunctions (emergency operation), errors

NOTE The maximum heat generator temperature limit is paramount to the heat generator switching differential and stops the heat generator in case of exceedance.

With control devices operated purely as a heating circuit expansion, the setting of the temperature has no effect.
