NOTE: If any changes must be made to the

commissioning configuration (e.g. selecting a

different probe), it is strongly advised that a

factory reset is performed and that the heat

pump is re-commissioned entirely. Changing

individual settings during the commissioning

process may cause commands to be ignored or

cause the heat pump to stop working correctly.

NOTE: If these steps are confirmed on the

controller during commissioning but haven’t

been carried out, any failure in the system will

be outside of warranty.

When checks are completed and ‘Next’ is selected, the

type of temperature measurement devices to be used

in each heating zone must also be selected:

 User Interface (usually in zone 1 – heating

system controller)

 Temperature probe (option for temperature

probe 1 to 3, for additional zones).

 Mechanical thermostat (option for mechanical

stat 1 to 3, for additional zones).

Using a mechanical stat limits the level of heating

control on the zone from the UI. Heating in zones

using temperature probes can be fully controlled

using the UI.

Selecting ‘Next’ will bring you to the ‘Temperature

check’ menu.

7.2.2 Temperature Check

This screen displays the temperatures currently being

read by all thermostats. It is the duty of the installer

to ensure that all thermostats are installed and

working correctly, and the boxes on this menu should

not be ticked unless all displayed temperatures have

been confirmed to be within an acceptable, accurate

and expected range.

7.3 Electrical connections (SH)

This menu provides a list of electrical connections that

should be made prior to commissioning for space

heating. The list is based on the schematic zone

diagram selected and also the type of temperature

devices that will be used in each zone. Once you have

confirmed all checks and select ‘Next’, you will return

to the commissioning menu where you can now

access the ‘Water flow check’ menu.

7.4 Water flow check

Select ‘Run Test’ to begin water flow check. The

circulation pump will be tested first by running it for

30 seconds. When the timer reaches zero, the pump

will continue to run in 30 second bursts until flow is

confirmed, which allows time for the installer to

check that the pump is working. Once you have

checked that flow is detected, click ‘Continue’ to

confirm that the pump is working correctly. Do not

confirm that the pump is working in this menu

unless you have physically checked it, as the UI

requires your input and does not detect this

automatically.

Once this is successful, the compressor will be run for

5 minutes. As the test runs, the screen will give you

information on the status of the heat pump and the

time remaining on the test. If you do not have flow or

if there is a problem, you can stop the test.
