If the secondary supply temperature detected by the maximum temperature thermostat becomes too high, the heat exchanger control and the primary pump will be stopped immediately. The secondary pump will continue to run to dissipate the excessive heat into the secondary system, if the parameter SEP-04 takes one of the values 2 or 4.
