If set to YES, the boiler /system shuts down when the temperature
exceeds the WWS SETPOINT.

Temperature at which boiler shuts down, operation is below this.
If boiler is running using either OA RESET or WWS and the OR
OVR input is closed the OA RESET slope is overridden and runs at
local setpoint until OR OVR input opens.
OA RESET

PUMP HOURS
ROTATE TIME 240 HRS 1-1000 HRS
If ROTATION is set to SYS HRS, ROTATE TIME is used to switch
pumps when this time expires. This time is measured against the
actual time the system pump is enabled. This would include a post
purge time.
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.
SUMMER PUMP JOG OFF
ON/OFF
MON-SUN
Used with Outdoor Reset, Jogs the local and system pump(s) for
POST PRGE time when system is in summer shutdown. Jog once a
week @12:00 AM.
The menu item OVR ENAB IN WWS and ALWAYS ENABLED
must be set to OFF for the jog function to work,
ZERO RUNTIME PUMP1 PUMP1- PUMP2
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.
PUMP1 TIME 0-999999 Hours
Indicates how many hours the HeatNet control has accumulated on
pump 1.
PUMP2 TIME 0-999999 Hours
Indicates how many hours the HeatNet control has accumulated on
pump 2.
ALWAYS ENABLED OFF ON/OFF
ON = Pump never shuts off. Used when there is only 1 system pump
in the system.
