Overheat Protection

In the event of excessive heat, when “SysSupplyTemp” becomes higher than the value of parameter SST-02 + 5K, the heat override signal at the output “OverheatProt” will take the value “1”. The secondary circuits will open their valves to dissipate this heat.

The overheat protection stops when “SysSupplyTemp” gets lower than SST-02.
