If ROTATION is set to PUMP HRS, ROTATE TIME is used to
switch pumps when the pump's time difference is greater than
ROTATE TIME. Whichever pump has the least time and is at least
below the other (pump's time - ROTATE TIME) will switch to the
enabled state. This selection is used to equalize run time on the
pumps.
New menu screen follows.
This menu allows the clearing of a pump's runtime counter.
Discretion is advised in clearing only one pump's hours after
replacement and then using ROTATION set to PUMP HRS. This
would cause the pump whose runtime was cleared to run until it's
time exceeded the other older pump.
Indicates how many hours the HeatNet control has accumulated on
pump 1.
Indicates how many hours the HeatNet control has accumulated on
pump 2.

across boiler is less than DELTA TEMP setting.
Time in minutes to keep local circ. pump on after boiler stops
Pump never shuts off.
ON: The master boiler will keep its pump/valve on when no boilers
are running. Prevents deadheading the system flow.
ON: Outputs a 0-10VDC or 4-20mA signal from J4 pins 1 & 5 that is
proportional to the fire rate of the boiler. Connect to a VFD
controlling a Local pump.
This is an adjustable flow proving time to allow slower valves to
open before proving flow.
