CAUTION

Equipment Damage Hazard.

Can damage the TIM connection beyond repair.

Disconnect the TIM cable prior to opening or closing

the thermostat cover.

NOTE: Allow sufficient clearance below the thermostat to

plug in the TIM cable.

Install the remote-mounted sensor(s) about 5 ft. (1.5 m) above

the floor in an area with good air circulation at average

temperature. (See Fig. 2.)

NOTE: Only TR21 models with neither setpoint adjust-

ment nor bypass can be used for temperature

averaging.

Sensor.

IMPORTANT

To avoid electrical interference, which can cause

erratic performances, keep wiring runs as short as

possible and do not run thermostat wires adjacent to

the line voltage electrical distribution systems. Use

shielded cable (Belden type 8762 or equivalent for

2-wire). The cable shield must be grounded only at

the controlled equipment case.

Mounting Subbase

The subbase mounts horizontally or vertically.

IMPORTANT

• When using the internal temperature sensor, the

device must be mounted horizontally (with the LCD

facing upwards). Precise leveling is not needed.

• When using remote sensors, thermostat mounting

orientation does not matter.

Wall mounting (using standard drywall screws) is standard.

Mounting to a 2 in.(50.8 mm) by 4 in. (101.6 mm) wiring box

can be accomplished:

— for a horizontal box, no extra hardware is required.

— for a vertical box, part 209651A is required.

— Mount to European standard wall box 2.4 in. (having 61 mm

between mounting screws in a horizontal line) with or

without adaptive hardware.

1. Position and level the subbase.

NOTE: A level wallplate is only for appearance. The

thermostat functions properly when not level.

2. Use a pencil to mark the mounting holes.

(Refer to Fig. 6.)

3. Remove the subbase from the wall and drill two 3/16 in.

(4.76 mm) holes in the wall (if drywall) as marked. For

firmer material such as plaster or wood, drill two 7/32 in.

(5.56 mm) holes.

4. Gently tap anchors (provided) into the drilled holes until

flush with the wall.

5. Position the subbase over the holes, pulling wires

through the wiring opening.

6. Loosely insert the mounting screws into the holes.

7. Tighten mounting screws.
