Switch OFF the motor and restart it
at the main ON/OFF switch. The
device will carry out the following
self-test:
&
Mixer close (150 seconds)
&
Pump ON (10 seconds)
&
Mixer open (10 seconds)
&
Mixer close (10 seconds)
Then standard control mode recom-
mences.
2.
Note the rotational direction of the
mixer motor during the self-test.
Then set the mixer manually to the
"Open" position.
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.
