INSTALLATION

When Installing this Product…

Read these instructions carefully. Failure to follow the instructions can damage the product or cause a hazardous condition.

Check the ratings given in the instructions and on the product to make sure the product is suitable for your application.

Installer must be a trained, experienced service technician.

After completing installation, use these instructions to check out the product operation.

Fig. 2. Typical location of thermostat

Location

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 (uncoole d) a rea s s uc h a s a n outside wall behind

the thermostat.

Install the thermostat about 5 ft (1.5m) above the floor in an area with good air circulation at average temperature. See Fig. 2.

IMPORTANT

or remote-mounted sensor.

To avoid electrical interference, which can cause erratic performances, keep wiring runs as short as possible and do not run thermostat wires a dja ce nt to the line voltage electrical distribution systems. Use shielded cable (Belden type 8762 or equivalent for 2-wire and Belden type 8772 or equivalent for 3-wire). The cable shield must be grounded only at the controlled equipment case.

Q7300 Subbase with Remote-Mounted Temperature Sensor(s)

If only the remote-mounted temperature sensor(s) is used to sense and control room temperature, then install the thermostat in an area that is accessible for setting and adjusting the temperature and settings.

If both the subbase and remote-mounted temperature sensor(s) are used to sense and control room temperature, then install the subbase about 5 ft above the floor in an area with good air circulation.

Install the remote-mounted sensor(s) about 5 ft (1.5m) above the floor in an area with good air circulation at average temperature. See Fig. 2.

If multiple remote sensors are required, they must be arranged in a temperature averaging network consisting of two, three, four, five or nine sensors. See Fig. 3 through 8.

NOTES:

— When sensor averaging, the T7147A can be substituted

— Up to four T7147As can be used in parallel to place the

Mounting Subbase/Wallplate

The subbase/wallplate mounts horizontally on the wall or a 2 in. by 4 in. wiring box. Position the subbase/wallplate horizontally on the wall or on a 2 in. by 4 in. wiring box.

Position and level the subbase/wallplate. NOTE: A level wallplate is only for appearance. The

Use a pencil to mark the mounting holes. See Fig. 9.

Remove the subbase/wallplate from the wall and drill two 3/16 inch holes in the wall (if drywall) as marked. For firmer material such as plaster or wood, drill two 7/32 inch holes. Gently tap anchors (provided) into the drilled holes until flush with the wall.

Position the subbase/wallplate over the holes, pulling wires through the wiring opening.

Loosely insert the mounting screws into the holes.

Tighten mounting screws.

IMPORTANT

All wiring must comply with local electrical codes and ordinances.

Follow equipment manufacturer wiring instructions when available. Refer to the Wiring section for typical hookups. A letter code is located near each terminal for identification. Refer to Table 6 for terminal designations.

Electrical Shock Hazard. Power supply can cause electrical shock.

Disconnect power before beginni ng installation.

Loosen the terminal screws on the subbase/wallplate and connect the system wires. See Fig. 10.

IMPORTANT

Use 18-gauge, solid-conductor color-coded thermostat cable for proper wiri ng. If using 18- gauge stranded wire, no more than ten wires can be used. Do not use larger than 18-gauge wire.

Securely tighten each terminal screw.

Push excess wire back into the hole.

Plug the hole with nonflammable insulation to prevent drafts from affecting the thermostat.

Mounting Thermostat on Subbase/Wallplate

The thermostat mounts on the subbase/wallplate after it is installed:

Engage the tabs at the top of the thermostat and subbase/wallplate. See Fig. 11.

Press the lower edge of the case to latch.

NOTE: To remove the thermostat from the wall, first pull out

at the bottom of the thermostat; then remove the top.

A. ENGAGE TABS AT TOP OF THERMOSTAT AND SUBBASE OR WALLPLATE.

B. PRESS LOWER EDGE OF CASE TO LATCH.

SETTINGS

Using Thermostat Keys

The thermostat keys are used to:

• set current time and day,

• program times and setpoints for heating and cooling,

• override the program temperatures,

• display present setting,

• set system and fan operation,

• configure Installer Setup,

• check Installer System Test.

See Fig. 12 for key information.

Setting System and Fan (select models)

The system default setting is Heat. The fan default is set so the fan operates continuously in Occupied periods, Unoccupied period recovery times and with the heating and cooling equipment in Unoccupied periods. Use the System and Fan keys to change the settings. Fan and system operation are configured in the Installer Setup options.

The system settings are: — Em Heat (T7200E, T7300/Q7300C,D,H): Emergency heat

relay is on continuously. Thermostat cycles highest stage of heat. Cooling sys tem is o f f. Comp resso r is de -energi zed.

— Heat: Thermostat controls the heating. — Off: Both the heating and cooling are off. — Cool: Thermostat controls the cooling. — Auto: Thermostat automatically changes between heating

and cooling depending on the indoor temperature.

M4824A

Fig. 11. Mounting thermostat on subbase/wallplate.

The fan settings are:

— On: Fan operates continuously in occupied period. — Auto: Equipment controls the fan in the Unoccupied

periods. The Intelligent Fan™ operation (Installer Setup number 17) offers three choices for the fan operation in Occupied periods:

— fan turns on only when there is a call for heat or cool. — fan oper ates continuously in Occu pied periods. — fan is on continuously in Occupied periods and

Unoccupied period recovery times.
