Installation Compliance
All field wiring made during installation must
comply with:
- National Electrical Code NFPA 70 and
any other national, state, provincial or
local codes or requirements.
- In Canada, CSA C22.1 Canadian
Electrical Code Part 1, and any other
local codes.
Line Voltage Connections
1. Connect 120 VAC power wire to the line
voltage leads located behind the front con-
trol panel.
2. Route the incoming 120 VAC power wire
through the right side jacket panel.
3. Use the wire nuts provided to ensure a tight
and secure connection.
4. The unit is provided with a service switch,
check local code requirements for compli-
ance.
If local electrical codes or conditions
require an additional service switch, the
installer must provide and install a fused
disconnect or 15 amp (minimum) service
switch.
Thermostat Wiring
1. Connect room thermostat or the end switch
(isolated contact only) of a relay control
panel to the Room Thermostat Snap-set
located on the rear jacket panel.
2. Remove the snap-set cover and connect the
thermostat wiring to terminals C and 1 per
Fig. 17.
3. For proper operation install the room ther-
mostat on an inside wall away from influ-
ences of heat and cold, i.e. water pipes,
areas of draft, lighting fixtures and fire-
places.
4. Set the thermostat anticipator (if applica-
ble) as follows:
- Set for 0.2 amps when wired directly to
the Room Thermostat Snap-set.
- Set to match the total electrical power
requirements of the connected devices
when wired to zone relays or other
devices. Refer to the relay manufactur-
ers’ specifications and the thermostat
instructions for additional information
on the anticipator setting.
Outdoor Temperature Limit
1. The ELITE may operate with a variable
primary operating temperature using an
outdoor reset control provided by the
installer.
2. Remove the factory jumper across termi-
nals 9 and 10 of the wiring terminal.
Connect the outdoor limit control to those
terminals.
3. Set the operating limits of the outdoor limit
control as follows:
- Maximum operating temperature of
180ºF.
- Minimum operating temperature of
150ºF.
