The owner is responsible for making all connections and setting
the appropriate dip switches.
When connected, the unit will be controlled by a remote
thermostat.

The number 3 dip switch must be in the enabled
(UP)
position to activate the remote thermostat. (See the installation
instructions supplied with the remote thermostat.)
IMPORTANT:
The thermostat connections provide 24 V AC only.
If using a digital/electronic wall thermostat, ensure it is
compatible with 24 VAC signal. See the Installation Instructions
for the wall thermostat.
NOTICE:
Damage to a wall thermostat or to the 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.
