Switching the system on and off
The system is switched on and off at the rotary switch in the
position "Operating Mode"
(See section 3.3.3 for
procedure).
Water pressure display
When switched on, the controller can be used to display the
system pressure (water pressure) of the internal circuit (heating
circuit) (see section 3.3.2 for procedure).
The water pressure should be between 1.5 and 3.0 bar in heating
mode. If it is less than 1.5 bar, the water pressure must be
increased by refilling the system (see heat generator installation
instructions).
If the water needs to be topped-up frequently, find out the cause
and have the fault corrected as soon as possible.
Thawing (automatic function)
At low outdoor temperatures and corresponding humidity values,
the external heat pump unit may ice up. This icing impairs
efficient operation. The system detects this condition automati-
cally and starts the melting operation. After 8 minutes at most, the
system returns to normal mode.
