2.5 Heating circuit rapid warm-up

A rapid warm-up of the heating circuit can only be activated 
if the remote control is set to position “rapid warm-up 
process”. 
Rapid warm-up means that the mixer is fully started up 
and the heating circuit pump is switched on. There is no 
regulation  of  the  flow  temperature.  The  heating  circuit 
rapid warm-up should only be activated if the maximum 
flow temperature exceeds the current store temperature. 
The heating circuit will be switched off if the maxiumum 
flow temperature is reached.

2.1 Weather-compensated heating circuit:

The flow set temperaure for the heating circuit results 
from the outdoor temperature and the chosen heating 
curves. This flow set temperature can also be changed with 
a remote control and the parameters “day correction/night 
correction”. The control adjusts the current heating circuit 
flow temperature to the determined flow set temperature 
by opening/closing the heat circuit mixer.

2.2 Timer (daily programme): 

  

 

The timer determines whether the day correction or the 
night correction is used for changing the flow set tempe-
rature. If one of the time frames of the timer is “active”, 
the night correction is used. If none of the time frames is 
active, the flow set value is changed due to the day cor-
rection. A time frame is “active” when the current time is 
between the switch-on and the switch-off time.

2.3 Remote control:

The remote control allows manual adjustment of the hea-
ting curve (+/-15 K). Moreover, the heating circuit can be 
switched off or a rapid warm-up process can be started 
with the remote control. The remote control is option al 
and it is not included in the full kit.

2.4 Heating circuit shutdown:

The heating circuit can be switched off manually if 
• the remote control is set to “Heatlp. off” 

The heating circuit is shut down automatically if 
  the adjusted maximum flow temperature is reached
  the  outdoor  temperature  is  higher  than  the  adjusted 

summer temperature. 

  the flow set temperature sensor is faulty.
•  or  the  heating  circuit  at  the  controller  is  deactivated 

(permanently off)

Heating circuit shutdown means that the heat circuit pump 
is switched off and the mixer is shut down.

Function overview

All settings for the HKM2 have to be adjusted with 
the corresponding menu of the connected control-
ler! Please read the manual for the controller in 
order to use all functions of the HKM2.
