s 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:
The Zoneline thermostat
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.
CAUTION:
Damage to a wall thermostat or to the Zoneline
electronics can result from improper connections. Special
care must be used in connecting the wires. No line
voltage connections should be made to any circuit.
Isolate all wires in building from line voltage.
