1. Hot water tank temp sensor (T1)
The sensor should be put in the sensor tube which is
installed
in hot water tank
.
2. Floor heating water temp sensor (T2)
2.1 Floor heating temp sensor has been installed on the
inlet water pipe inside heat pump before leave factory.
2.2 If floor heating system doesn’t install water tank,
installer needn’t deal with the temp sensor (we don’t
suggest the system without floor heating water tank)
2.3 If floor heating system has water tank, installer should
remove the sensor from inlet pipe and install it in water
tank (we suggest install a floor heating water tank).
Note: Water temp sensors probe can’t touch water directly,
should be put in sensor tube which is installed in water
tank, like the drawing.
Introduction of the system
3. Heat pump circulating water pump (P1)
3.1 This water pump is controlled by heat pump controller.
3.2 Hot water side and floor heating side share the circulating water pump.
3.3 By setting parameter F5 through password 0814, installer can set P1 stop or
non-stop when both hot water and floor heating side have reached preset temp.
3.4 P1 rated water flow is: 4700L/H, head should be ≥5m + water pressure drop
of other parts outside heat pump.
4. Floor heating terminal water pump (P2)
4.1 This water pump is not controlled by heat pump controller, but by floor heating
room thermostat. When any floor heating start, P2 will start, when all floor heating
stop, P2 will stop.
4.2 The wiring diagram of P2 connect to room thermostat can refer to following
parts.
