If the radiator is too cold check that
the radiator TRV is set to a high
enough level.
A room may become warm enough without
the radiator being more than lukewarm.
Is the programmable thermostat
set too low?
Check that the temperature on the
programmable thermostat is set high enough
to start the heat pump.
Is the mains power switched off?
Check that the heating switches are switched
ON, including the switch located next to the
outdoor unit.
In the event you have checked the points
opposite,
and the system still fails to operate
normally, you can manually reset the system by
turning off the power, waiting 60 seconds then
turning it back on.
If the system still does not operate
as normal,
check the display on the controller
for a fault code (typically a number and a letter
for example 7H) and contact your housing
association, making reference to the
displayed code.
