Wiring must comply with applicable codes, ordinances, and regulations.

CAUTION: Voltage Hazard.

Can cause electrical shock or equipment damage. Disconnect power before beginning installation.

Wire entire panel before applying transformer power.

Install thermostats using instructions provided with thermostats.

Connect thermostat to zone panel. To connect wire to the panel, strip

approximately 1/4 in. of insulation and push wire into terminal. To

release wire, press the button on top of the terminal. In retrofit applica-

tions, trim end of wire if not straight.

E/AUX

If the thermostat has separate E and Aux terminals, install a jumper

between the two terminals.

When the zone panel cover is off, the EMERGENCY HEAT/PURGE OVERRIDE button

is visible.

When the panel is in Purge (at startup or after a call for heat/cool), pressing this but-

ton stops the Purge, which saves time during installation or troubleshooting.

All other times, pressing the button puts the zone panel into Em Heat mode so that

all calls for heat are handled by the auxiliary heat.
