Pump Exercising: After every three days of no
operation, the control will exercise the pump for 10
seconds. The % of Pump Performance LED will be
on during exercising.
•
Post Purge: A 20 second post purge is available
once the heat demand is removed or control
enters WWSD. The purging holds the last speed
used.
•
As variable speed output modulates, the control
flashes the % of Pump Performance LED on for ¼
second and off for ¼ to 2 1/2 seconds.
•
A 2 second delay from demand to actually starting
the pump is used to prevent issues with a noisy
demand relay signal.
