Test 1 To Avoid further problems we recommend you set
the units up in test mode before starting the heat pump.
Firstly in test mode run the pump, press
seconds. The controller will display TEST. Immediately press the top left button to turn the
pump on and leave it running while in test mode. When the pump is running a little house with
a circle around it in the status window of the controller.
The unit wants to see at least 17 l / min flow to activate
the flow switch, if there is not enough flow the unit will
never operate. You should have a flow meter installed,
if you haven't now is the time to buy one.
If you look into the flow meter you can see the flow in
litres per minute. In this picture you can see a flow rate
indicated, this shows 25l/min NOT 35l/min
If the flow rate is too low you need to fix this before moving on.
Starting it up in heating mode:
Turn up your thermostats to send a run signal to the unit, the pump will start immediately, a
little house with a circle round it appears in the status window, when the compressor starts
after 3 minutes, you will see the symbol for the compressor in the status screen. It's a little
milk churn with a c in it.
The pipework will begin to heat up, check the flow temperature by pressing blue view button
once, the temp of the flow is shown next to a symbol of a house in a circle. Over time this will
warm up, now check all the radiators or U floor loops are hot as well.
Starting the System in hot water mode
In hot water mode check that the 2 ports are sending water into the hot water cylinder, Using
the view button (blue) on the remote controller check the hot water cylinder temperature and
note it down, the hot water temperature is displayed when the tap symbol shows.
After 15 minutes of running check the hot water temperature again, it should have risen, again
note the temperature. If the temperature has not risen check the blue temperature sensors is
installed properly. If the unit is running well it should heat the cylinder to 48C without needing
the immersion heater
Not enough hot water.
The Water storage temperature is lower (48C) than a normal fossil fuel cylinder. It's important
to check that any shower or bath mixers do not further reduce the water temperature. Using
your thermometer check that the hot water comes out the tap at the same temperature it
leaves the cylinder. If it doesn't you might need to make adjustments to taps mixers etc.
DON'T raise the cylinder temperature to compensate.
