a fan-forced convector.
This thermostat cannot be used with:
• a resistive load under 1.25 A
• a resistive load over 16.7 A
• a system driven by a contactor or a relay (inductive load)
• a central heating system
SUPPLIED PARTS
• One (1) thermostat
• Two (2) 6-32 mounting screws
• Two (2) solderless connectors

TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER
PANEL TO AVOID ELECTRICAL SHOCK.
• The installation must be performed by a qualified electrician and must
comply with electrical codes of your region.
• Do NOT install the thermostat in an area where it can be exposed to water or
rain.
• Avoid locations where there are air drafts (such as the top of a staircase or
an air outlet), dead air spots (such as behind a door), or direct sunlight.
• Do not install the thermostat on a wall section that conceals air ducts,
chimney pipes or stove pipes.
• Install the thermostat about 1.5 m (5 feet) high, on an inside wall facing the
heater.
• Install the thermostat onto an electrical box.
• This thermostat has tinned copper wires for line and load connections.
Special CO/ALR solderless connectors must be used if the thermostat will
be connected to aluminium wires.
• The thermostat wires are not polarized; either wire can be connected to the
load or to the power supply.
• Keep the air vents at the top and bottom of the thermostat clean and free
from obstructions.
Installation guidelines

69-2793EF—05 6
1) Loosen the screw and remove the faceplate of
the thermostat from its wallplate. (The screw
remains captive on the wallplate.)
2) Make the connections using solderless
connectors for copper wires. The thermostat
wires are non-polarized; this means either wire
can be connected to either terminal.
3) Install the wallplate to the electrical box.
4) Set the configuration switches on the back of
the thermostat’s faceplate (see page 6).
5) Install the faceplate of the thermostat back on
the wallplate and tighten the screw.
6) If there is a protective film or sticker on the
thermostat’s screen, peel it off.
7) Apply power to the thermostat. Verify the
installation by checking that the heater can be
turned On and Off by raising and lowering the
setpoint using the and buttons.

METTRE LE SYSTÈME DE CHAUFFAGE HORS TENSION AU PANNEAU
ÉLECTRIQUE AFIN D'ÉVITER TOUT RISQUE DE CHOC ÉLECTRIQUE.
• L’installation doit être effectuée par un électricien qualifié et doit être
conforme aux codes de l'électricité en vigueur dans votre région.
• Ne PAS installer le thermostat à un endroit où il risque d’être exposé à l’eau
ou à la pluie.
• Éviter les endroits où il y a des courants d'air (comme dans le haut d'un
escalier ou une sortie d'air), où il manque de circulation d’air (comme
derrière une porte) ou qui sont directement exposés au soleil.
• Ne pas installer le thermostat sur un mur qui dissimule des conduits d’air ou
d’une cheminée.
• Installer le thermostat à environ 1,5 mètre (5 pieds) du sol, sur une cloison
intérieure faisant face à l’appareil de chauffage.
• Installer le thermostat sur une boîte électrique.
• Le fils du thermostat servant à la connexion de l’alimentation et de la
charge sont en cuivre étamé. Si vous les reliez à des fils d’aluminium, utiliser
des connecteurs spéciaux sans soudure CO/ALR conçus à cette fin.
• Les fils du thermostat ne sont pas polarisés; le sens du branchement n’a
donc aucune importance.
• Garder les ouvertures d’aération du thermostat propres et dégagées en tout
temps.

1) Dévisser la vis et séparer la façade du
thermostat de sa plaque murale. (La vis reste
captive sur la plaque murale.)
2) Faire le branchement en utilisant des
connecteurs sans soudure pour fils de cuivre. Les
fils du thermostat sont non-polarisés; le sens du
branchement n’a donc aucune importance.
3) Installer la plaque murale sur la boîte électrique.
4) Configurer le thermostat à l’aide des sélecteurs
à l’arrière de la façade (voir la page 6).
5) Retourner la façade du thermostat sur la
plaque murale et serrer la vis.
6) Enlever la pellicule autocollante de l’écran s’il y
en a une.
7) Mettre le système de chauffage sous tension.
Vérifier l’installation en s’assurant que le
système de chauffage puisse être activé et
désactivé en augmentant et en diminuant la
température de consigne à l’aide des boutons
