Auxiliary controls on your Zoneline.
External Fan (Obtained locally)
When connected, an auxiliary or external fan can be
controlled with the indoor fan motor on the Zoneline.
Connections provide 24 V AC to energize a remote relay,
turning on the external fan.
Central Desk Control
When connected, the unit can be turned ON or OFF with
a switch located at the Central Control Panel. A separate
wire pair must be run from each separate controlling
switch to each individual Zoneline.
Refer to MODE 2 on page 5 for fan setting options.
Remote Thermostat
When connected to a remote thermostat, the indoor air
temperature sensing is shifted from the unit to the
remote thermostat. For this reason, the units will operate
slightly differently when connected to a remote
thermostat. The following chart shows the unit operation
when connected to a remote thermostat.
NOTE: The Class 2 Mode setting (Mode 6) must be set to
ON " " for the unit to operate with a Class 2 Remote
Wall Thermostat. (See the installation instructions
supplied with the remote thermostat and Mode
instructions on page 7.)
IMPORTANT:
connections provide 24 V AC only.
If using a digital/electronic wall thermostat, you must set
it to the 24 V AC setting. See the Installation Instructions
for the wall thermostat.
