• 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

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.
