Regulation of the mixer is
undertaken by the heat pump
manager. If required, it calls for
the boiler and adds more hot
water until the desired set return
temperature is reached.
The boiler is called via the heat
generator 2 output of the heat
pump manager and the mode of
operation of heat generator 2 is
coded as being “constant” (see
Chap. 8.9.1 on p. 184).

The boiler can also be
requested for DHW preparation
to achieve higher hot water
temperatures.
If an additional flange heater is
installed in the hot water tank
the boiler is only used for
reheating and thermal
disinfection when the flange
heater is active in heating
operation.
