Heat pump mode

The 

HP mode

 can be used to force an afterheating, 

when a heat pump is used for the store afterheating. 
For that purpose, the store contents are mixed in or-
der to decrease the store temperature, which leads 
to a heat pump demand. 
When the heat pump mode has been activated, the 
optimum operating temperature of the heat pump 

T-HP opt

 must be adjusted in order to determine 

the  store  fl ow  sensor  temperature  from  which  on 
the heat pump mode becomes active. When the heat 
pump mode is active, the primary pump is run at the 
adjustable 

Speed HP

.

The heat pump mode becomes active in the follow-
ing cases:
•  During sliding set value adaptation, the tempera-

ture at the store fl ow sensor falls below T-HP opt.

•  T-HW set has been adjusted lower than T-HP opt 

and the temperature at the store fl ow sensor falls 
below the set temperature calculated.

Only after the cold start phase has been completed, 
will the heat pump mode become active.

The 

Blocking protection

 function can be used for 

protecting the pumps against blocking after standstill. 
Blocking protection is executed daily at 12 o'clock. 
It will energise relay 4 (primary pump) and, if the 
circulation has been activated, relay 2 (circulation 
pump) as well.
Pump runtime is 3 seconds. First, the circulation 
pump starts. Then, the primary pump starts. The HW 
heating, the hot start of the heat exchanger and the 
circulation have a higher priority than the blocking 
protection. In the case of a draw-off, the blocking 
protection for the corresponding pumps is aborted.
