Unit Enable=OFF
Source=KEYPAD
Unit Enable is an external signal or a keypad setting that keeps the unit off when the setting
is OFF and allows it to run if there is a call for cooling. The source for the signal is
selected in the 3td line and can be:
1. KEYPAD, in which case the selection is made in line 2 and would be normally selected
as ON. This is the normal setting when no external signals are controlling the unit.
2. SWITCHES, in which an external switch is wired across terminals #25 and #35.
3. NETWORK, used with BAS signal, which is wired to the three communication ports.

Available Modes setting is the standard COOL or TEST as selected from the available
modes imbedded in the menu. The 4
th
line is a reminder that the ON/OFF switch on the
front panel (FP) must be in the OFF position before the MODE can be changed. This
prevents a mode change while the unit is operating.
