Heat pump circulator has failed?
The heat pump will not operate if the heat pump circulator has failed. Refer
to "Heat Pump Is Not Operating" page 25 . Phone your nearest Rheem
Service Department or Accredited Service Agent to arrange for an inspection.
•
Water heater size
Do you have the correct size water heater for your requirements? The sizing
guide in the sales literature and on the Rheem website (www.rheem.com.au
or www.rheem.co.nz) suggest average sizes that may be needed.
•
Air temperature is cold – defrost mode
If this method of low ambient temperature operation is used, the heat pump
will enter a defrost mode when ice is sensed on the evaporator coil. The
recovery rate of the heat pump is reduced in this mode due to the lower
operating air temperature and heating of water is reduced during the defrost
cycle.
WATER TOO HOT
The water heater, during both normal heat pump operation and auxiliary booster
operation
(optionally
heat pump fault), will heat the water to a temperature of 60°C to 65°C. It is
recommended to set the auxiliary booster thermostat setting to 65°C.
WATER NOT HOT ENOUGH
You may find that due to heavy hot water usage the water temperature may be
lower than normally expected, due to insufficient heating time being allowed.
Additional storage or an in series booster may be required to be installed under
these circumstances.

installed, will operate instead. The storage tank will be heated to the set point
during these periods. Auxiliary boost will turn OFF and heat pump will start
operating as normal when air temperature increases to 5°C or higher.
•
Thermal cut out activated
Has the thermal cut out for the heat pump compressor activated?
If the thermal cut out has activated, the heat pump will not operate for a period
of 20 minutes to 2 hours and display alarm on the control panel. The water
heater will make two more attempts to start. If the thermal cut out is tripped
again after the third attempt, the system will enter lock
BMS, this will alert the user that the unit is not operating.
