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.
NOTE: 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.
