INSTALLATION When Installing this Product...
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous condi-
tion.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service techni-
cian.
4. After installation is complete, check out product opera-
tion as provided in these instructions.
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment circuitry.
Disconnect power supply before installation.
IMPORTANT
T6570 Series are line voltage powered devices.
All wiring must comply with national and local electri-
cal codes, ordinances and regulations.
Provide disconnect means and overload protec-
tion as required.
T8570 Series thermostats must be powered by an
Approved 24 Vac, Class 2 transformer (such as a
W6380 Relay Control Center).
Location
The T6570, T8570 series thermostats are the temperature
control element in a fan-coil or air-conditioning system. They
must be located about 1.5m (5 ft.) above the floor in a position
with good air circulation to sense room temperature.
The optional T8109 sensor can be used to sense temperature
in return air ductwork, instead of at the thermostat
IMPORTANT
Do not mount device where it can be affected by:
1. Drafts or dead spots behind doors or in corners.
2. Hot or cold air from ducts.
3. Radiant heat from the sun or appliances.
4. Unheated (uncooled) areas such as an outside wall
behind the thermostat.
5. Concealed pipes or chimneys.
