10 Operation
The heat pump operation takes place by means of the
basic operating panel. This is easily accessible in a
plastic housing mounted on the heat pump. The user
has
2 knobs and a lit display at his disposal
(Fig. 26).
Fig. 26 : Basic control panel
The heat pump has no
separate main switch. In emergency the
system MUST be switched off by means
of the specified circuit breakers.
The circuit breakers
MUST be so reachable as to en-
sure a switching off at any time.
Further notes on the control operation can be found
in the current OTE Operating Instructions,
which are supplied with every heat pump.
10.1 Safety functions
Following safety features are implemented from both
Hard- and Software:
-
Electronic control and safety devices for the
compressor
-
High pressure pressostat
-
Start delay to avoid
compressor chopping.
-
Frost protection function
-
Start-up- and run-down times of the fans
10.2 Running costs
During the first heating season, higher running costs
can generally be expected, depending on the residual
moisture in the building - up to 50%.
10.2.1 Flow temperatures
In order to achieve an optimum heat pump operation,
the lowest possible heating system flow temperatures
(and hot water temperatures) are to be aimed at. The
max. system temperature for heat pumps of the
OLW Series is to be limited to 60°C.
NOTE:
An increase of the room temperature by 1°C means a
5-7% increase in energy consumption.
10.2.2 Ventilation
Intermittent intensive ventilation according to own
requirements should be carried out, especially during
the heating period. Intermittent intensive ventilation is
much more energy-efficient
and thus more economical.
Continuous ventilation should be avoided on principle.
