CAUTION:
• Installation must be carried out by a certified electrician and must comply with national and local
electrical codes.
• To prevent severe shock or electrocution, always cut the power at the service panel before working
with wiring.
• Use this thermostat for resistive loads only.
• Do NOT install the thermostat in an area where it can be exposed to water or rain.
• Avoid locations where there are air drafts (top of staircase, air outlet), dead air spots (behind a
door), direct sunlight or concealed chimney or stove pipes (except for floor heating systems).
• For a new installation, choose a location about 1.5 m (5 ft.) above the floor.
• Install the thermostat on an inside wall facing the heating system (except for floor heating systems).
• Install the thermostat onto an electrical box.
• Use special CO/ALR solderless connectors if you connect the thermostat to aluminum wires.
• Keep the thermostat's top and bottom air vents (openings) clean and unobstructed at all times..

NOTE:
• The wire distance between the master thermostat and each CT230 unit must not exceed 500 ft.
(150 m). 20-AWG wires are recommended.
• The floor sensor cable must not exceed 200 ft. (60 m).

ENGLISH
Insert the floor sensor cable through one of the two openings on the wallplate and connect
the sensor wires to terminals 4 and 5 (no polarity).
• The sensor wires must not come in contact with the electrical wires and must be routed
outside the electrical box and follow the wall down to the floor.
• Position the sensor cable such that it does not come in contact with the floor heating
wires. The sensor must be centered between two floor heating wires for best temperature
control.
• Do NOT staple the sensor head (the plastic end) to the floor. Doing so might damage the
sensor. Any damage might not be noticeable during testing but can become apparent
several days later.
