7.1 General Troubleshooting
7.1.1 How do I know the unit is working
Check that the LED light next to the on/off button is on. If this light
is not lit, then the system is not operating. Simply press & hold the
cancel button for 3 seconds (unlock the controller) then press the
on/off button to turn the unit on and check that the LED light is lit.
7.1.2 Water from the heat pump is not hot enough
If you find your heat pump is not supplying hot water then this is
most likely related to one of the following:
1.
Hot water has been largely consumed and the system
needs to reheat the replenished water.
Check the temperature on the unit and then leave for an hour
and see if this has increased.
(Please note if the system has been completely emptied
recovery may take up to 4 - 5 hours)
2.
A timer might be incorrectly set turning the unit off at the
wrong time.
If your screen is showing the 'time on' or 'time off' icon then
it appears a timer has been set. When timers are set this
turns the unit on and off at the set time periods. Remove all
timers, by holding the cancel button for 3 seconds to unlock
the controller, then press the time on or time off buttons,
proceeded by the cancel button to wipe the timers. Should
you wish to set timers for your system please refer to section
6 of this guide on how to do so.
3.
The unit has been switched off.
Check the unit and ensure the red LED light is showing. If
not, unlock the controller by holding the cancel button for
3 seconds (the lock icon will disappear from the display
screen). Then simply press the on/off button and now the red
LED light should be lit.
4.
The connected power is still in off peak supply only.
We recommend that power is available to the unit 24/7. This
ensures that the unit can work to its maximum efficiency.
If your water is not hot enough and only off peak power is
supplied to the unit then the system cannot operate until the
off peak period is active. If you believe your system is only
available during off peak supply please contact our service
team for further assistance.
5.
There may be an issue between the heat pump unit and
the hot water outlet.
Check the controller for the in tank temperature. If the
controller is indicating the tank is at or near the set
temperature then locate the PTR valve on the left hand side
of the unit. Carefully release the PTR valve to release water
directly from the tank.
NOTE: Water expelled may be extremely hot.
Carefully check if the water released is hot. If water is hot,
then there appears to be an issue beyond the heat pump
unit. If so, please contact your plumber or our service team
for further assistance.
