Thermostat Installation

For installation of thermostats:

301 00 154 (12 volt)

301 00 153 (24 volt)

Note: These instructions illustrate the use of the thermostats sen-

sor to monitor room temperature. Two alternatives are available:

#1) Heaters internal sensor - not available for D8LC.

#2) Remote external sensor- see technical manual for more details.

D5LC heaters may be supplied with this connector connected to the

heaters internal temperature sensor. This must first be disconnected

to allow connection to the thermostat. The D8LC switch harness by

default comes with the wiring for a remote external sensor, this must

be disconnected to allow connection to the thermostat.

Switching on

Turn the on-off switch to the “ON” position. Switch the heaters’ tem-

perature setting by adjusting the temperature control dial to the

desired temperature range.

Step 1

Select a mounting location

which will be representative of

the average temperature of the

area being heated. Avoid

mounting near heater outlets,

windows, doors, electrical appli-

ances or in areas receiving

direct sunlight.

Step 4

Connect the switch harness

wires to the thermostat as

shown on inside sheet.

Please see operators guide for

proper start up and shut down

procedures. See technical manu-

al for more technical information

Step 2

Route the switch harness from

the heater to the thermostat

mounting location.

Step 3

Mount the thermostat as shown

using proper mounting hardware

and the slots provided on the

thermostat base. Pull the switch

harness through the

thermostat base

access hole.

Mounting slots

Lowest setting - approx. 50°F

Mid setting - approx. 65°F

Highest setting - approx. 85°F

D1LC and D3LC compacts only. On OEM installs the ‘red” &

“green” indicator lights illuminate. On after market installs only the

“Red” light illuminates.

D5LC and D8LC heaters only. The green light on the thermostat is

a blink code diagnostic light. It will provide a fault code if a problem

occurs within the heater. Please see corresponding technical manu-

als for activation, interpretation and recommendation.

It is recommended that when using return ducting, not to use this wire. Not using the grey or black wire defaults the heater to use the

temperature sensor on the control unit of the heater.

Use of the grey wire defaults the heater to use the sensor on the thermostat.

The sensor on the control unit provides a more accurate reading of the overall air temperature, whereas the sensor in the thermostat

gives more of a spot reading of the air surrounding the thermostat.

D8LC

* discard the remote external sensor wire

(grey sleeve that comes stock with every

D8LC harness) containing the 2 core black

wire and white wire.

Remove grey wire and brown wire from pins

6 & 7 at the round connector.

Remove black wire at pin 12 and insert into

pin 7 at round connector.
