Central Desk Control

When connected, the unit lock-out is released
and it can be turned ON or OFF with a switch
located at the Central Desk Control. A separate
wire pair must be run from each separate
controlling switch to each individual Zoneline. A
24V AC circuit powers the CDC system. No external
power is required.
Remote Thermostat
The unit will be controlled by a remote
thermostat.
IMPORTANT:
The Zoneline thermostat connections
provide 24V AC only.
If using a digital/electronic wall thermostat,
you must set it to the 24V AC setting. See the
Installation Instructions for the wall thermostat.
NOTICE:
Damage to a wall thermostat or to the
Zoneline electronics can result from improper
connections. Exercise extra attention when
connecting blue and black wires. No line
voltage connections should be made to any circuit
in the thermostat. Isolate all wires in building from
line voltage.
