A high setting may result in noise and vibrations in the heating sys-
tem.
A too low setting may result in high pressure-, or low heat circulation
flow alarms.
Adjusting the speed for the constant-speed pump
▪
Start with maximum speed setting.
▪
Check that the circulation pump is running by listening, placing a hand on the circulation pump and listen for air in the system.
▪
If flow is detected, normally within 60 seconds, decrease the setting until the flow is so low that the F in the default display disap-
pears.
N
If no flow is registered, check the system for air and bleed if nec-
essary. See chapter "Filling and bleeding". Also check that the
flow sensor is in the correct direction (check the arrow on the
flow sensor) and also that all heat system valves are open.
▪
Set the speed on the pump to the value where sufficient flow is guaranteed.
▪
Check that the delta temperature (the difference between the supply line and return line) should be 7–10°C. The delta is checked in
the INFORMATION MENU, see description as follows.
Check the delta temperature
N
The time it takes to get a correct and stable reading of the delta is de-
pendant of the size of the heating system.
The following settings are made in the INFORMATION MENU. If not already in the INFORMATION MENU, enter the INFORMATION MENU
from the default display by pressing (<) arrow. Use + or – to move up and down in the menu.
