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 "heat-
ing" 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.
