Extension kit for heating circuit with mixer
Checking the rotational direction of
the mixer motor
1.
Switch ON/OFF switch A at the
extension kit first OFF and then ON
again. The device will carry out the
following self-test:
&
Mixer "Close" (150 s)
&
Pump "ON" (10 s)
&
Mixer "Open" (10 s)
&
Mixer "Close" (10 s)
Then standard control mode
resumes.
2. Note the rotational direction of the
mixer motor during its self-test.
Then set the mixer manually to
"Open" again.
Note
The flow temperature sensor must
now sense a higher temperature. If
the temperature falls, either the
motor is turning in the wrong direc-
tion or the mixer set is incorrectly
fitted.
