Valve position checks
Valve in neutral position
If the valve motors have become loose and the valves
have come out of position, adjust the position of the
valves using a wrench to obtain the right valve setting.
Adjust the valves according to the previous table
"heating" and install the valve motors unpowered, with
the arm set to neutral position (current on, control
current off).
At input control signal the valves rotate 90°.
Caution
When changing the heating/cooling mode,
there is a delay of approximately 60 seconds
before the valves change their positions.
