0HWKRG2: Setting the controller as "Cooling Only" in the Service Mode of a Wired Controller
All wired controllers can be configured to skip heating mode as a selectable option by the occupant. It is recommended to use
method 1 of this document. If only the controller is setup to skip heating mode, the mode can still be changed to heating
operation via wireless controller or central controls.
To configure the wired controller as cooling only (skip heat mode), refer to the installation manual of theapplicable wired
controller.
