Heat Pump; Condensate Drain Rear Side Hybrid Heater - Winterwarm Qwikshift QSG Installation Manual

4.5.1. Installation requirements
Following these requirements when placing the thermostat
to ensure the heater functions correctly:
• Make sure that air can circulate around the
thermostat.
• Make sure the sun does not shine directly upon the
thermostat.
• Do not place the thermostat on a cold wall.
• Place the thermostat on an inner wall free from
draught.
• Never place the thermostat within the throw of the
heater.
• Never mount the thermostat near the aerials of
internal communication networks. These emit
radiation that can disturb the thermostat. Keep
several meters distance.
In all cases, the communication between the heater
and the thermostat is based on a four wire, low-voltage
connection. (see the electrical wiring diagram in §11.).
Follow these instructions to prevent malfunction of the
installation and damage to the thermostat or air heater:
• Use a cable with the following specifications:
– Signal cable.
– Shielded ..
– Minimum dimensions: 4 x Ø0.34 mm
– Maximum length: 200 m.
CAUTION! Keep the thermostat cable separated from the
mains cables.
CAUTION! Connect the cable's earth shield only to the
earth terminal inside the air heater. Do not connect the
other end of the cable's earth shield.
NOTICE A cable with a thickness of less than 0.34 mm
will result in a poor signal.
NOTICE A cable that is not shielded and may result
in a disturbed communication in an EMC-unfriendly
environment.

One single Smart Controller of Building management
System (BMS) can conytrol multiple hybrid heaters.
Consult the user manual of the Smart Controller for further
information.

4.6 Heat pump

NOTICE Make sure that a heat pump is connected with
the right power output corresponding to the hybrid heater.
Use the same cable as specified in clause 4.4. for the
connection between the heat pump and hybrid heater.
CAUTION!
with the thermostat connection mentioned above. This will
damage the heat pump.

The heat pump has a similar connection inside. The
connections of the wires have to correspond for a proper
communication.

4.7 Condensate drain rear side
hybrid heater
The hybrid heater has two condensate drains. The drain
at the rear side is connected to a condensate collecter
below the heat exchanger. If the lower outlet temperatures
of the heat exchanger are not set lower than 15°C, no
condensate will be formed. With lower temperatures the
change of condensate increase and a drainage hose may
be imstalled in these cases.
Do not mix the connection to the heat pump
