Table 5 Monitored Parameters
Inlet Water
(Return) Temp.
This is the temperature at which the heating
water returning from either the heating circuit
or to the hot water storage cylinder is
entering the heat pump.
Ambient temperature if the appliance
has been off for a time.
No greater than 65°C in normal
operation.
Outlet Water
(Flow) Temp.
This is the temperature at which the heating
water leaving to either the heating circuit or to
the hot water storage cylinder is returning to
the heat pump.
Ambient temperature if the appliance
has been off for a time.
The value should be approximately 5.0
degrees Celsius below the heating flow
temperature in heating mode.
Exhaust
(Discharge)
Temp.
This is the temperature of the disharge line
(the gas leaving the compressor travelling to
the condenser).
Ambient temperature if the appliance
has been off for a time.
Not greater than 130°C in normal
operation.
This is the temperature of the water in the hot
water storage tank.
Not greater than 65°C in normal
operation.
This is the temperature of the suction line
(the gas entering the compressor from the
evaporator).
Ambient temperature if the appliance
has been off for a time.
Varies between negative and positive
temperature depending on the mode.
This is the temperature of the evaporator coil.
Ambient temperature if the appliance
has been off for a time.
Varies between negative and positive
temperature depending on the mode.
This is the temperature of the outside air.
Dependent on local climate condition,
typically between -10°C and 30°C.
This is the pressure of the suction line (the
gas entering the compressor from the
evaporator).
This should read between 7.0 and 20.0
bar if the appliance is off and between
2.0 and 12.0 bar in normal operation.
Exhaust
(Discharge)
Pressure
This is the pressure of the disharge line (the
gas leaving the compressor travelling to the
condenser).
This should read between 7.0 and 20.0
bar if the appliance is off and between
15.0 and 45.0 bar in normal operation.
This is the current speed of the compressor.
This is the requested speed of the
compressor.
This is the current speed of the fan motor.
This is the current speed of the second fan
motor (only applies to AS03 models).
This is the calculated value at whch point the
suction temperature is too high.
Varies based on the current mode and
conditions.
This is the calculated value at whch point the
discharge temperature is too high.
Varies based on the current mode and
conditions.
Module Temp.
Protect Value
This is the calculated value at whch point a
module temperature is too high.
Varies based on the current mode and
conditions.
This is the current incoming AC voltage
measurement.
Typically between 210Vac and 240Vac.
This is the current incoming AC current
measurement.
Typically between 1Amp and 27Amps.
