•With the frost protection setting "cycle operation", there is no continuous demand for the heat generator, in contrast to continuous operation.

•With system frost protection active, the heating circuit pumps are switched on and the mixed heating circuit valves are closed.

•As long as the measured flow temperature of the mixed heating circuits or the heat generator temperature in the direct heating circuit, respectively, does not drop below the current setpoint room temperature (RTFrost or RTNight), no demand value is forwarded to the heat generator.

•When the flow temperature drops below the current setpoint room temperature, heating is activated.

•Once the setpoint flow temperature has reached the setpoint room temperature and the set time ("System Parameters" menu, parameter 19) has passed, the demand value to the heat generator is retracted and the mixed heating circuit valve closes while the pumps continue running.

•If no data are detected from the outside sensor (e.g. because the sensor is defective), only the pumps are switched on while heating is disabled.

•The set minimum and maximum limits are taken into account while heating.

•When the heat generator is activated, the set start-up protection conditions of the heat generator are applied. This can mean that the heating circuit pumps are switched off temporarily.

Frost protection function in case of heat generator fault

If system malfunction message 30-3 or 31-3 occurs (e.g. switch- on failure of the burner(s) due to fuel shortage or burner malfunction), priority pump switch-off functions such as boiler start-up protection, DHW priority etc. are disabled if frost protection is active.

The heating water circulated in the heating circuits adopts the overall mean room temperature and reduces or delays any freezing.
