Honeywell Tradeline Q7100A,C,D Thermostat Subbases Installation Manual

Application

The Q7100 Thermostat Subbases provide electronic control of commercial 24 Vac single or multistage heat pump or conventional heating and cooling systems. Select models have terminals for light emitting diodes LEDs, remote temperature sensors and remote setback timer. The LED models have up to two field configurable LEDs and up to two factory assigned LEDs. Refer to Table 1. All Q7100 Thermostat Subbases require a common wire to the supply power.

Location

Subbase without Remote-Mounted Temperature Sensor

Install the subbase 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 subbase 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.

Subbase with Remote-Mounted Temperature Sensor(s)

Install the subbase in an area that is accessible for setting and adjusting the temperature and settings. 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. 1. Do not mount the sensor(s) 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.

If more than one remote sensor is required, they must be arranged in a temperature averaging network consisting of two, three, four, five or nine sensors. See Fig. 2 through 6.

Subbase Installation

The subbase can be mounted horizontally on the wall or a 2 in. x 4 in. wiring box. Position the subbase horizon- tally on the wall or on a 2 in. x 4 in. wiring box.

1. Position and level the subbase (for appearance only). The thermostat will function properly even when not level.
2. Use a pencil to mark the mounting holes. See Fig. 7.
3. Remove the subbase 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.
4. Position the subbase over the holes, pulling wires through the wiring opening.
5. Loosely insert the mounting screws into the holes.
6. Tighten mounting screws.

Wiring

All wiring must comply with local electrical codes and ordinances. Refer to Fig. 9 through 15 for typical hookups. A letter code is located near each terminal for identification.

CAUTION

Disconnect power before wiring to prevent electrical shock or equipment damage.

1. Loosen the terminal screws on the back of the thermostat and connect the system wires. See Fig. 8. IMPORTANT Use 18 gauge, color-coded thermostat cable forproper wiring.
2. Securely tighten each terminal screw.
3. Push excess wire back into the hole.
4. Plug the hole with nonflammable insulation to prevent drafts from affecting the thermostat.
