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.
