INSTALLATION INSTRUCTION

SURFACE WALL MOUNTING STEPS

without removing the front cover

Figure of Surface wall mounting installation without removing the front cover

1. Use the template provided with the heater.
Allow 4 in. (102 mm) minimum below heater.

Recommended installation height is 12 in. (305 mm)
below the heater for a better temperature regulation.

Locate positionning of the supply wire
and make a 1 in. (25 mm) diameter hole.

Firmly install the 4 screws supplied to the wall.
DO NOT OVERTIGHT SINCE YOU WILL NEED
TO SLIDE THE HEATER AT STEP 3.

2. For an installation with “Loomex” fl exible wire,
use the single-screw wire holder by unscrewing the screw,
make the connections and screw back the wire holder.
Do not let more than 12 in. (305 mm) of loose wire
between the heater and the wall.

For an installation with “BX” cable, follow step 4. b)
of the RECESSED WALL MOUNTING STEPS or

SURFACE WALL MOUNTING STEPS by removing the
front cover.

3. Align the oversized part of the holes with the screws
already on the wall, then slide the heater downward.
Make sure that the 4 screws are well supported at the top
of the keyhole (small part).

4. Once the heater in place, fi nish tightening the 4 screws with
a 5 in. (127 mm) minimum rod screwdriver through the
grilles of the heater as shown. DO NOT USE
A DRILL WITH A SQUARE BIT AT THIS STEP
BECAUSE YOU COULD DAMAGE THE GRILLES.

Do not let more than 12 in. (305 mm) of loose wire between
the heater and the wall.
b) For “BX” cable,
use the appropriate knock-out (back or bottom of the heater)
with a connector (not supplied). Remove the protection plate
(4 screws), make the connections and put the protection
plate back (4 screws).

5. a) Recessed wall mounting
Install the casing in the wall opening using the recessed
mounting holes on the side or the front of the casing.
Do not try to force the casing in the opening.
b) Surface wall mounting
If you have decided to remove the front cover for
a surface wall mounting installation, follow step 3 and 4
of the SURFACE WALL MOUNTING STEPS
without removing the front cover.

6. Reconnect the electronic thermostat to the casing
by cliping both parts of the black plastic connector together.
Replace the fl at cable in the wire clips.

7. Put the front cover back by sliding it downwards.
The 2 tabs of the front cover fi t into the 2 slots of the casing.
Screw back the 2 bottom screws.

8. Test the heater by pressing the “Hour-glass” button to activate
the boost heating mode. It is possible that a slight heating smell
emerges from the grilles, which is totally normal and will stop
after a few minutes of operation.

USER INSTRUCTION

Appears when the setpoint is displayed

Standby button

Boost heating button

(Hour-glass)

Temperature Display and Setting

The thermostat normally displays the ambient measured
temperature.

The screen is backlit at maximum intensity for 15 seconds
when any button is pressed.

To view the setpoint temperature, press once on either
adjustment button. The setpoint temperature will appear for
5 seconds. A small arrow appears on the top left corner of the
screen.

To change the setpoint temperature,
press the appropriate adjustment button.
Setpoint range: 50 °F to 86 °F (10 °C to 30 °C).

The thermostat using proportional regulation determines the
heating intensity necessary for the electric heating heater to
precisely maintain the ambient temperature according to the
setpoint. The number of fl ames indicates the percentage of heat
calculated by the electronic thermostat, such as 25%, 50%, 75%
and 100%.

To change the temperature display format from °C to °F
or vice versa, press the 2 “Adjustment” buttons simultaneously
for 2 seconds.

Boost Heating (Hour-glass)

For boost heating mode, use the “Hour-glass” button. Press
once to activate this mode and to see the remaining time
fl ashing (“min” is now displayed in the bottom right corner).
Display will stop fl ashing after 5 seconds. While the remaining
time fl ashes, press again the “Hour-glass” button to set the
minutes to 5, 10, 15, 20, 25 or 30. If display does not fl ash any
more, press again the “Hour-glass” button to turn off the boost
heating mode. Whenever needed in the boost heating mode, use
the “Adjustment” button to increase or decrease, by increments
of 1 minute, the remaining time. When in the boost heating
mode ambient temperature is not displayed.

Display Backlit

By default, the screen is backlit at mid-intensity at any time
and at maximum intensity for 15 seconds when you press any
button.

Setting or ambient temperature

Adjustement buttons

Heating intensity (Flame)

Display Backlit (continuation)

To deactivate the mid-intensity backlit, press the “Standby” and
the bottom adjustment buttons simultaneously for 2 seconds.
The letters “bL” appear on the screen. Press one or the other
adjustment buttons until “Off” appears on the screen.
The thermostat will automatically save any changes and return
to normal display if you do not press any buttons for 5 seconds.

Keypad Lock

This feature eliminates unwanted temperature adjustments and
the use of different modes of the thermostat.
Before activating this function, make sure you have set the
temperature setpoint to the desired temperature. Press the
“Standby” and the up buttons simultaneously for 2 seconds.
A pad lock icon appears on the screen to confi rm that your
settings are now locked. Repeat this step to deactivate this
function.

Standby

The standby mode enables thermostat shut down at end
of heating season. Take note that when this mode is activated,
the heater does not heat, no matter the room temperature or
the setpoint. WARNING! The standby mode does not cut the
current to the heater.
For any maintenance, cut power to the heating system at the
main electrical panel to avoid any risk of electrical shock.
To put the thermostat in standby mode, press the “Standby”
button for 2 seconds. The standby icon appears on the screen to
confi rm that the device is in standby.
To return to the heating mode, press the “Standby” button. The
thermostat will then return to normal display.

Power Outage

During a power outage only the setpoint temperature is saved
in memory.
The screen then returns to normal display and any other
functions go back to their default settings.
Note that it can take between 0 and 10 seconds before heating
begins.

Offset of Ambient Temperature

The heater thermostat has been calibrated in laboratory in
order to be precise at ±0.5 °C. Somehow, depending of the
conditions in which it is installed, the ambient temperature
could be different from the one displayed on the heater
thermostat. If you want the thermostat to display the ambient
temperature shown on your thermometer, you must use the
“Offset of Ambient Temperature” function.

Steps to follow (you must have a thermometer):

1. Put the heater in standby mode. (See Standby).

2. Press the “Hour-glass” button for 2 seconds until “Off”
appears on the screen and then “0.0”.

3. To calculate the correction factor
(could be a negative value):
TT = Ambient temperature according to the thermometer
TA = Temperature shown on the heater thermostat
Celsius: (TT - TA) or Fahrenheit: (TT - TA)
2 4

4. Use the adjustment buttons to enter the correction factor
by increments of 0.5

5. Press the “Hour-glass” button in order to quit the “Offset of
Ambient Temperature” function.

6. Press the “Standby” button to get back to normal display.
The correction factor is now taken in to account by the
thermostat. The ambient temperature displayed on the
thermostat should now be the same as the one displayed on
your thermometer.
