CONTROLLER OPERATION
MINIMUM R6 PUMP SPEED LEVEL SETUP
When starting the system, the minimum RPM speed level must be determined, in
which the R6 circulation pump enables the minimum flow. First, use the switch to set
the highest or at least the medium pump operating power. Now, select the manual
operation mode in the controller and check at which pump speed level the pump can
still provide the flow in the system. The minimum pump level is saved with the S6.11
parameter.
SOLAR COLLECTOR PUMP - IMPULSIVE MODE
Impulsive mode of sun collector pump is set with parameter S6.8=1. If collector
temperature is higher as minimum collector temperature, the pump is activated each
15 minutes for 10 seconds. This way a realistic collector temperature is acquired. This
setting is used in case if collector sensor isn't mounted directly into the collector body.
