Planning information for brine op-
eration
The heat source for operation as a brine/water heat pump (horizon-
tal absorber or vertical heating elements) must be configured in ac-
cordance with the cooling capacity specified in the technical data.
With the
ThermSelect
® version, the cooling capacity to be provided
by the heat source can be reduced by up to 25%, as the source is
not fully utilised over the entire heating period.
With the
ThermSelect
®
Pro
version, the cooling capacity to be pro-
vided by the heat source can be reduced by up to 50%, as the brine
evaporator is exclusively operated in parallel with the air evaporator
with outdoor temperatures of below approx. 5°C and the source is
therefore utilised to a minor extent.
CAUTION!
Freezing of the heat source due to incorrect operat-
ing setting!
Heat source becomes unusable for a long period of
time.
Therefore:
-
With this version, it is compulsory to exclusively
operate the brine evaporator in parallel with the air
evaporator.
-
A changeover to alternative mode, i.e. exclusive
operation as a brine/water heat pump, overloads
the heat source.
CAUTION!
Freezing of the heat source due to incorrect dimen-
sioning (overload)!
Heat source becomes unusable for a long period of
time.
Therefore:
-
In case of doubt regarding the efficiency of the sur-
face, a geothermal response test must be carried
out by an appropriate professional.
CAUTION!
Damage to devices through freezing!
The plate heat exchanger is destroyed on the source
side, if the brine freezes.
Therefore:
-
Monitor flow with safety devices (flow switch, pres-
sure switch).
-
The safety devices must be installed on site. The
regulations of the responsible authorities must be
complied with.
Furthermore, dirt catchers, bubble separators and a rinsing device
must be envisaged.
NOTE!
Warranty becomes void if this information is disre-
garded and damages can be traced to one of the
listed causes.
