selections are entered at keyboard.

Location

Install the thermostat about 5 ft (1.5m) above the floor in an area with good air circulation at average temperature. See Fig. 1.

Do not install the thermostat where it can be affected by: — drafts, or dead spots behind doors and in corners. — hot or cold air from ducts. — radiant heat from sun or appliances. — concealed pipes and chimneys. — unheated (uncooled) areas such as an outside wall

behind the thermostat.

Wallplate Installation

The thermostat can be mounted horizontally on the wall or on a 2 in. x 4 in. wiring box. Position wallplate horizontally on the wall or on a 2 in. x 4 in. wiring box.

Position and level the wallplate (for appearance

only). The thermostat functions correctly even when not level. Use a pencil to mark the mounting holes. See Fig.

2. Remove the wallplate from the wall and drill two

3/16 in. holes in the wall (if drywall) as marked. For firmer material such as plaster, drill two 7/32 in. holes. Gently tap anchors (provided) into the drilled holes

until flush with the wall. Position the wallplate over the holes.

Loosely insert the mounting screws into the holes.

Tighten the mounting screws.

Setting up T8665A to Send Signal to W8665A,E Receiver Module

The T8665A Thermostat must be set up to send signals to the W8665 Receiver Module. Use the W8665A Receiver for single-zone applications. Use the W8665E RF Zone™ Panel for up to three T8665A Thermostats for multizone applications.

Single Zone Applications (one T8665A/ one W8665A)

Receiver to the On position.

NOTE: Observe that the Zone 1 LED on the W8665

flashes.

Press the thermostat Fan key to the On position.

The receiver accepts the message, stores identity and then stops flashing the Zone 1 LED. The thermostat is now set up to send signals the W8665A Receiver.

NOTE: The word On and a fan blade appear in the

Set the System and Fan keys to the desired loca-

tions.

NOTE: At any time, if you want to stop the thermostat

from sending signals to the W8665 Receiver, simply turn the DIP switch to the Off position. Follow the instructions in steps above to set up the thermostat again to send signals to the W8665A Receiver.

Multizone Applications (Up to three T8665A/ one W8665E)
