The order of sequence activation is set by assigning an order number for heating and cooling.


Configuration > Functions > Function activation > Heating/Cooling sequences >


As can be seen in the configuration example below:

  • In case of heating demand, the Exchanger (SEQ-B) will start first and Heating (SEQ-A) will follow second.
  • In case of cooling demand, the Exchanger (SEQ-B) will start first and the Cooling (SEQ-C) will follow second.

Sequence overlapping or dead band can be set by adjusting “Start Heating” and “Start Cooling” sequence parameters.

The adjustable range is -100% .. +100%.

A negative starting point will create sequence overlap while a positive starting point will delay the start of the selected sequence.
