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.
Outdoor reset ratio (boiler water temp/outside air temp).
WATER TEMP
AT
HIGH OA TEMP
Boiler water temp setpoint when OA temp is at HIGH OATEMP
These four setpoints determine the OA reset slope.
WATER TEMP
AT
LOW OA TEMP
Header/Supply setpoint when OA Temp is at LOW OA TEMP
The number of system pumps connected.
Time in minutes to keep system circ. pump on after boiler stops
NONE
SYSTEM HOURS
PUMP HOURS
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.
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,
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.
ON = Pump never shuts off. Used when there is only 1 system pump
in the system.
