4.4.3 Waterside Check
The ‘Waterside Check’ menu allows you to select whether temperature control is based on the ow or
return temperature. This will apply to heating curves, as discussed in section 4.4.12.
It is generally always recommended to set the temperature control based on the return temperature
(the default selection on the UI), unless it is absolutely necessary to use ow temperature instead for a
particular set up.
CAUTION: Flow control may lead to unnecessary stopping and starting of the heat pump.
Selecting Next will bring you to the waterside checks menu (gure 17).
A number of waterside checks must be carried out as part of commissioning, and must be ticked as
completed. In the Waterside check menu:
• The system must be ushed.
• The strainer must be tted to the return pipe and checked to ensure that it is
clean.
• The system must be pressurized (you must enter the system pressure).
• The system must be fully bled.
• The expansion vessel must be tted
• Membrane pressure of the expansion vessel must be checked and adjusted
Figure 17: Waterside Check
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 by scrolling across and pressing conrm. The following
options are available;
• 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.

NOTE: If any changes must be made to the commissioning conguration (e.g. selecting a different
probe), it is strongly advised that a factory reset is performed and that the heat pump is recommissioned
entirely. Changing individual settings during the commissioning process may cause commands to be
ignored or cause the heat pump to stop working correctly.
