– HEAT PUMP
The next step is to check whether the circulation pump is working properly. To do this, you force the maximum
flow rate and observe the reading from the flow meter. If there is no flow, you cannot proceed further. If there is
no flow, you should:
•
check that the relevant valves are open
•
check the correct installation of the flow meter
•
check that the pressure gauge (manometer) shows the pressure in the system
•
check that the green light on the circulation pump is on
•
check the correctness of the electrical connection of the circulation pump and the flow meter
The minimum medium flow rate should be set at 9 l/min for the 10K pump and 12 l/min for the 15K pump, and the
maximum flow rate should not exceed 28 l/min for the 10K pump and 35 l/min for the 15K pump. It is very import-
ant to set after which sensor the compressor regulates. For users with a buffer, it is recommended to set the
regulation after the temperature of the water in the buffer. Otherwise, the Inlet/Outlet type of regulation should
be selected, along with specifying that the start and ongoing regulation are to be after Outlet. The recommended
mode of operation is “Always On.” When the heat pump is switched to hot water heating mode, you may find that
the maximum flow rate will be different from that of central heating operation. Set the appropriate minimum and
maximum values for DHW mode as well.
If the user has a DHW circulation pump, its operation algorithm should be set. The following modes are available:
• OFF
– always off
• ON
– always on
• ECO
– Ecological mode operating cyclically according to the setting of the following parameters
ECO switch-on time: the period of operation in ECO mode
ECO switch-off time: standby period in ECO mode
• CALENDAR
– always on when DHW heating is active in the calendar
• ECO CALENDAR
– operation as in ECO mode when DHW heating is active in the calendar
