Luxury Air Source Heat Pump-Monobloc System 23
Remarks for heating/cooling/domestic hot water version:
--
For Two- way valve (B1 and B2)
This function is reserved for two-way valve control. If an external two-way valve needs to be
controlled by the heat pump system, you can use these ports according to their output signal.
During space cooling mode, the ports (B1 and B2) will provide power 220-240V~ for use. During space
heating or domestic hot water mode, no power is provided.
--
For Water Tank Electrical heating Driving Signal (C1 and C2)
When connecting the electrical tank heater to C1 and C2, one extra contactor is needed. Please refer
to below drawing.
-- For 0-10V Control
If the external controller gives a voltage control signal of 0 to +10V, the heat pump will produce water
with different temperature according to a voltage-water temperature table. Once this control method is
in force, the external signal will control the setting outlet temperature of space heating/cooling, the
temperature setting of the wire controller is not in force anymore.
This control signal is for space heating and space cooling modes.
--
For External Control
This is to connect an On/Off control signal. When the signal is on (closed), the Heat Pump can
work. The running mode will be decided by the setting of the wired controller.
If the signal is off (open), the Heat Pump can’t work.
But if there is domestic hot water requirement the domestic hot water will not be affected by the
external signal. It will always work as per the setting of wired controller of the heat pump.
