Installing your THZ-100 Thermostat

Adding an optional wired sensor can be a benefit if the thermostat location is not the optimal location for

temperature measurement, or if temperature averaging is desired.

• A wired sensor can be connected to the S+ and S- terminals on the back of the unit

• This can be added to any of the wiring options detailed in the next pages

For optimum performance, mount the THZ-100 thermostat and/or remote sensor

• In an open living area where there is good air circulation

• On an inside wall

• Away from outside doors or windows

• At a height about 5 feet from the floor

Avoid installing the THZ-100 thermostat and/or remote sensor

• In direct sunlight

• Above radiators or air vents

• Near fans or portable heating units

• Near lamps or other incandescent lighting

• Near other heat generating electric appliances such as televisions, audio video equipment,

refrigerators, freezers, ovens, cooktops, etc.

Other precautions when installing the THZ-100 thermostat and/or remote sensor

• Make sure the cutout for the HVAC wiring is no larger than needed to make proper connections to the

thermostat

• If there is a large air gap in the cutout for the HVAC wiring, insulate around the wire and close off the

air gap

• Make sure the air vents in the THZ-100 thermostat and/or remote sensor are clear of dirt, dust, or

any construction material.
