Compressor
The fully hermetically sealed compressor is designed for
high efficiency heat pump applications.
A suitable starting
current limiter for the compressor is installed in the indoor
unit.
Electric booster heater
The appliance is fitted with an electric booster heater
(immersion heater). At low outdoor temperatures, the ap-
pliance operates in bivalent-parallel mode. The appliance
can also be combined with an additional heat generator.
Condenser
The condenser takes the form of a plate heat exchanger,
which is built of stainless steel and insulated on all sides
against condensation and heat loss.
3.2.2 Outdoor unit
The outdoor unit is intended to be installed outside. The
outdoor unit is designed as a horizontal split evaporator.
The indoor unit is connected to the outdoor unit with refrig-
erant lines, along with electrical control and power supply
cables.
Evaporator
The evaporator is a part of the outdoor unit and consists
of copper pipes in a set of aluminium fins.
i
Information
With an air/water heat pump, frost may form on
the evaporator fins of the outdoor unit, depending
on the air temperature (below approx. +7°C), air
humidity and the operating point. The evaporator
fins are automatically de-iced again in the cyclical
defrosting mode of the heat pump.
Fan
The outdoor air is blown across the evaporator by a quiet
fan.
3.2.3 Heat pump control unit
The OCHSNER heat pump controller includes devices
for controlling heat pump heating systems with a cooling
function as well as DHW heating. In its standard version,
the heat pump control unit consists of the OTE controller
and the master controller, both of which are installed in
the indoor unit.
The OTE controller can control the following system circuits
and heat generators:
►
1x direct circuit (heating and/or cooling)
►
1x mixed circuit (heating and/or cooling)
►
1x directly heated DHW cylinder (with electric booster
heater)
►
1x heat pump (heating and cooling)
►
1x additional heat generator (electric booster heater
or enable contact for external heat generator)
3.3 Name plate
Two name plates are attached to the indoor unit to identify
your heat pump. In addition, a label with the serial number
is attached to the right-hand casing panel of the appliance.
