CONFIGURATION
8.D.10.c Warm Weather
To navigate to the Warm Weather Conguration Screen, touch the Miscellaneous Features on the Conguration Screen,
then touch the Warm Weather Icon on the Miscellaneous Features screen.
The Warm Weather Conguration Screen allows
adjustment of the following parameters:
•
Temp Min – Upon an active warm weather shutdown condition, this is the temperature at which the unit will reset the
shutdown condition to satisfy a heat demand.
•
Temp Max – This is the temperature at which the warm weather shutdown condition will occur.
•
Feature Options – This parameter provides the ability to either disable warm weather shutdown or upon a warm weather condition,
congure the unit to shut down immediately or to shut down after the current heat demand is satised.
•
Summer Kick CH – The amount of time the unit pump is energized if it hasn’t cycled for an extended period of time.
•
Summer Kick DHW – The amount of time the DHW pump is energized if it hasn’t cycled for an extended period of time.
•
Summer Kick SYS – The amount of time the SYS pump is energized if it hasn’t cycled for an extended period of time.
•
Summer Kick Period – The duration of time between heat demands that the boiler will wait before exercising the boiler,
DHW, and system pumps.
There are three options for Warm Weather Shutdown (WWSD). WWSD is only applicable to boilers. It is not
mandatory, so it can be enabled/disabled on the WWSD conguration screen.
1 - WWSD - Shutdown Immediately
When the outdoor sensor measures an outdoor air temperature that exceeds the WWSD set point, one of the following
two conditions will occur. If the unit is idle, upon a call for heat, the unit will not turn on to satisfy a heat demand. If the unit
is running to satisfy a call for heat, the unit will immediately shutdown. In either case, the WWSD icon will appear on the
home screen.
2 - WWSD – Shutdown After Demand is Satised
When the outdoor sensor measures an outdoor air temperature that exceeds the WWSD set point, one of the
following two conditions will occur. If the unit is idle, upon a call for heat, the unit will not turn on to satisfy a heat
demand, and the WWSD icon will be shown on the home screen. If the unit is running to satisfy a call for heat, the
unit will satisfy the heat demand and then the WWSD shutdown icon will appear. As long as the unit is in a WWSD
condition, no additional heat demands will be satised.
3 - WWSD – Disabled
Control ignores any WWSD set points, and operates normally.
