4.4.5 Remote
On/Off
For Remote On/Off operation, terminal positions are
provided to connect a remotely located, On/Off switching
control device. If the A/C unit is turned on and the
E2
controller receives a remote input signal to turn off the
A/C unit, the controller disables all control outputs and a
message "Off by Remote Shutdown" appears in the main
display screen. The A/C system will automatically be re-
enabled when the remote On/Off signal calls for the A/C
unit to turn back on.
The control device may be an On/Off switch, thermostat
or a humidistat. If customer provided, the remote On/Off
control contacts must be sized appropriately. The Remote
On/Off contacts must have a minimal rating of 24 VAC.
Refer to the electrical drawing included with the A/C unit
for the electrical specifi cations and for wiring details.
