OPERATION AND SAMPLE CONNECTION
ALWAYS FOLLOW FIRST AND FOREMOST THE CONNECTION DIAGRAM
PROVIDED BY THE HVAC DESIGNER OR HEAT PUMP MANUFACTURER.
The accompanying figure shows an example of the arrangement
for connecting the heating/cooling radiator unit to the heat
collection circuit.
Connect the radiator output pipe to the heat collection circuit
return pipe. Direct the fluid returning from the radiator unit to the
heat collection circuit return pipe. If you know that there is a large
loss of internal pressure inside the heat pump, the heat pump
should be bypassed. If this is done, the fluid circuit will come
into operation when the heat pump comes to a halt. When this
happens the pressure loss in the one-way bypass valve Y2 must be
lower than the pressure loss in the heat pump.
NOTE: HEATING
The pump starts when the outdoor
air temperature drops below the
winter limit value set at the factory
(-5 °C).
NOTE: COOLING
The value set for the supply air
temperature of the active profile
(e.g.
At home
) controls the startup
of the pump. The pump starts when
the supply air setting is below the
temperature of the supply air that is
blown into the apartment.
NOTE
Due to the risk of humidity
damage, in a duct that has not
been insulated for condensation
the supply air temperature must not
fall below 16 … 20 °C.
NOTE
When selecting the relay, take
account of the maximum allowed
combined power supply (6W) of
the circuit card in the external
connection box, if the relay power
is obtained from the circuit board
+24V connector.
P Circulation pump. Not included in the delivery. The pump
should be suited to pumping liquid colder than the
surrounding air, due to risk of condensation (for example,
Grundfos Magna 1 25-80).
V
Solenoid valve. Not included in the delivery. The valve that is
chosen must be compatible with the heat collection circuit
fluid (for example, ELV05006, Stig Wahlström).
K Condensing water tube. Not included in the delivery.
IP De-aerator. Not included in the delivery.
S External electrical junction box for the MV
C
24 VDC relay/contactor for controlling the pump and the
solenoid valve. Not included in the delivery. (For example,
ABB CR-P024DC2)
Y One-way valve. Not included in the delivery.
Y2 One-way valve. Not included in the delivery. The pressure loss
must be less than the pressure loss of the heat pump.
