INSTALLATION

When Installing this Product...

1. Read these instructions carefully. Failure to follow them

could damage the product or cause a hazardous condi-

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.
