“priority” controller. The priority controller becomes the master temperature control
device for the system. To set priority:

1. Turn off the override if it is set on another controller. Press the “Override” key to
release priority. The Override indicator light will go out.
2. Select the new controller to take control. Press the “Override” key on the wired

operation panel. The first press will shut the unit off, which will invalidate the
Override ownership of the remote, and the second press will reactivate the unit
which will reinstall factory defaults and set the unit's panel the Override position,
the “Override” indicator will turn on. When unit is in standby, the first wired controller
to activate the unit will have priority and the Override indicator will turn on.

this remote control. Adjust the temperature using the “Up” and “Down” arrows.
