Condensation Protection Of Heat Generators

The heating circuit handles condensation protection like the DHWS priority function.

When heat generators minimum return temperature drops below the limit set in the single boiler or heating strategy, a condensation protection signal can be sent to the heating circuits.

The next diagram shows the mixed water (mixed water) temperature setpoint during condensation protection. If the condensation protection, occurs the water temperature setpoint will be decreased immediately to the minimum value, defined by the parameter MWT-02 minimum mixed water temperature. When the condensation protection signal returns to zero, the water temperature setpoint will be ramped up to its normal setpoint with a ramp function defined by the parameter MWT-04.
