Warm Weather
To navigate to the Warm Weather Configuration Screen, touch the Miscellaneous Features on the Configuration Screen,
then touch the Warm Weather Icon on the Miscellaneous Features screen.
The Warm Weather Configuration 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,
configure the unit to shut down immediately or to shut down after the current heat demand is satisfied.
•
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 configuration 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 Satisfied
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 satisfied.
3 - WWWD – Disabled
Control ignores any WWSD set points, and operates normally.
