Switching contact function

With pre-heating/supplementary heating, incorrect installation will result in unit damage.

If external pre-heating or supplementary heating is selected, the power supply for the component should be switched via an external relay.

Parameters: Switching contact

Set value: alarm, filter message, operating display, shutter, supplementary heating, pre-heating. One of the aforementioned external components can be switched with the potential-free switching contact (max. 5 A) of the basic circuit board (main board).

Additional settings for supplementary heating switching points

  1. Under Switching contact, select the Supplementary heating parameter.
  2. Under Supplementary heating
    • Set Supplementary heating parameter to yes.
    • Adjust switching point with Hysteresis setpoint temperature.
    • Set Supplementary heating parameter to no.
