8.C.4 Warm Weather Shut Down
Warm weather shut down allows the user to disable the heating system based on outside air temperature. It is
used for boilers only.
To navigate to the Warm Weather Quick Start Screen, touch the Warm Weather Icon on the Quick Start
Screen.
The Warm Weather Quick Start Screen allows adjustment of the following parameters:
• Temp Min – If the unit is in warm weather shutdown mode, it will resume normal operation when the air temperature
drops to this value.
• Temp Max – The temperature at which the
warm weather shutdown condition will occur.
• Feature Options – This allows the
shutdown to be enabled or disabled. When
enabled, and the outside air temperature
rises to the shut down (temp max) value,
this tells the controller whether to shut down
immediately or satisfy the current call for
heat before shutting down.
