Temporary Override Run Mode

The temporary override run mode sends setpoint data to the unit control module (UCM) from the setpoint data entered in the temporary manual override menu.

In temporary override run mode, most of the keypad functions lock out with these exceptions:

•The mode button still functions as in normal run mode.

•The fan button still functions as in normal run mode.

•Depressing the holdtemp button toggles the ZSM between the temporary manual override menu and override run mode. (if no button is pressed for 20 seconds while in temporary manual override menu, the ZSM exits to normal run mode, ignoring the temporary override settings.)

•Depressing either the ↑ or ↓ arrow while in the override run mode will cause the ZSM to toggle to the temporary manual override menu.

•The erase button will turn off the check filter icon if displayed.

•Simultaneously depressing and holding

the positive and negative sides of the “minus” and “plus” for four seconds will lock out the keypad.

•Time is not adjustable in this mode.

• The program button is disabled.
