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.
