Regulation of mixer M21 is
carried out 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 can also be requested
for DHW preparation to achieve
higher hot water temperatures.
The boiler is called via the 2nd
heat generator output of the heat
pump manager and the mode of
operation of the 2nd heat
generator is coded as being
"constant".
A flange connection enables the
additional installation of the RWT
750 solar heat exchanger.
