6.1.5 Forced withdrawal of superfluous heat
6.1.5.1 Forced withdrawal of superfluous boiler heat
In case the boiler temperature has exceeded 90 °C so called forced withdrawal of the superfluous heat into
the heating circuit will start. The fan and feeder are not active. In case the temperature is lower than the
current desired boiler temperature the boiler comes back into actual automatic regime (in case the boiler
temperature has reached 100 °C and the safety thermostat has been blocked the thermostat must be
manually de-blocked).
Mixing heating circuit
Forced withdrawal of the superfluous heat is activated in case the outlet boiler temperature 90
o
C has been
exceeded. The outlet boiler temperature by means of three-way mixing valve will be reduced to the maximum
heating circuit temperature (80
o
C – parameter P 77).
6.1.5.2 Forced withdrawal of superfluous water heater heat
If the temperature in water heater has exceeded 80
o
C the forced withdrawal of the superfluous heat into the
heating circuit will start (only in case of pump heating circuit).
6.2 SAPHIR regulator parameters
In he next tables there are listed parameters that can be changed by means of QAA 88 device. The way of
displaying and changing the parameters is described in chap. 6.3.1.
