Wiring of Heater

Refer to Wiring Diagram, Figure 4

1. Connect the black (L1) heater pigtail from ON/OFF switch to

the black power lead on the heater assembly.

2. Connect the red (L2) heater pigtail to the other black power

lead.

NOTE: L2/N heater pigtail is white for 277 volt model and must

be connected (through ON/OFF Switch) to a white Neutral

supply lead.

3. If not already done, connect building ground conductor to

green ground screw in heater back box.

Building Management Systems (BMS)

To utilize the BMS capabilities of this unit, remove the red

jumper wire between terminals A and B on the control terminal

board ( see figure 3, wiring diagram). Connect two wires from a

dry contact (no voltage) in the BMS system to terminals A and B.

NOTE: DO NOT REMOVE THE RED JUMPER UNLESS

CONTROL BY A BUILDING MANAGEMENT SYSTEM IS BEING

USED.

When BMS takes control, heater functions will not work, the

touch screen is locked, BMS light on the heater touchscreen

blinks.

When BMS releases control, heater functions are available,

heater resumes operating at previously programmed settings.

Refer to Operations Manual for programming options and details.

Installation of Grille and Control Wire Connector

1. Push ON/OFF switch into ON position.

2. Install (2) plastic covers on back box as follows:

(See Figure 5)

NOTE: Both top and bottom plastic covers are identical.

• TOP - Align the screw bosses on the back of the plastic

cover with the second hole down from the top of the back

box and attach it with the two screws provided.

• BOTTOM - Align the screw bosses on the back of the

second plastic cover with holes at the bottom of the back

box that are just above the fan deck mounting screws and

attach it with two screws provided.

3. Position the grille in front of the heater assembly, extend the

control wire connector from the heater assembly to the

matching connector from the back of the electronic control,

behind the grille. The connector is keyed so it will fit only one

way.

NOTE: Press the connector gently and firmly, but do not force,

making sure the clip on the connector engages.

4. Install the front cover by hooking the (2) tabs on top and

bottom plastic covers on one side then rotating the front

cover into place making sure that all four tabs are snapped

into the grille.

NOTE: Use caution when installing the grille to avoid trapping

the control wire in between the grille and heater assembly.

OPERATION

INSTRUCTIONS

Initial Setup Instructions (Performed by Installer)

NOTE: After installation, the installer should perform the follow-

ing procedures to ensure proper operation of the heater. See

“Customizing Heater Settings” for details on programming other

functions of the heater.

1. Switch the power on at the main circuit panel. When the

heater is first powered up the buzzer beeps for one second

and displays all indicators in high luminance and the POWER

button in half blue luminance for 3 seconds, then the unit will

turn OFF. When OFF, only the POWER button illuminates in

orange color in half luminance and all other buttons and

icons will be OFF. When OFF, if the POWER button is

touched, all 4 buttons will illuminate indicating the heater is

ON and the control panel is powered up. See Figure 6 for

Control Panel layout details.

POWER SUPPLY VOLTAGE MUST BE THE SAME AS

HEATER VOLTAGE RATING SHOWN ON HEATER NAME-
