Q700L SERIES 2000 COMMERCIAL HERMOSA YES NO NO 5 FEE (.5 MEERS) NO M482A Fig.. ypical location of thermostat or remote-mounted sensor. Location Subbase without Remote-Mounted emperature Sensor Install the thermostat about 5 ft (.5m) above the floor in an area with good air circulation at average temperature. See Fig.. 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. Subbase with Remote-Mounted emperature 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. 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 are required, they must be arranged in a temperature averaging network consisting of two, three, four, five or nine sensors. See Fig. 2 through 6. IMPORAN o avoid electrical interference, which can cause erratic performance, 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 and Belden type 8772 or equivalent for -wire). he cable shield must be grounded only at the controlled equipment case. 7047G 7047G Install the remote-mounted sensor(s) about 5 ft (.5m) above the floor in an area with good air circulation at average temperature.

Position the subbase horizontally on the wall or on a 2 in. x 4 in. wiring box.. Position and level the subbase or wallplate (for appearance only). he thermostat functions properly even when not level. 2. Use a pencil to mark the mounting holes. See Fig. 7.. Remove the subbase or wallplate from the wall and drill two /6 inch holes in the wall (if drywall) as marked. For firmer material such as plaster or wood, drill two 7/2 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.

Loosen the terminal screws on the subbase and connect the system wires. See Fig. 8. IMPORAN Use 8-gauge, solid-conductor color-coded thermostat cable for proper wiring. If using 8- gauge stranded wire, no more than ten wires can be used. Do not use larger than 8-gauge wire. 2. Securely tighten each terminal screw.. Push excess wire back into the hole. 4. Plug the hole with nonflammable insulation to prevent drafts from affecting the thermostat. NOE: After wiring, check that all connections are tight and secure. See Fig. 8. Loose or intermittent wire connections cause inconsistent system operation. FOR WRAPAROUND INSERION SRIP 7/6 IN. ( MM). FOR SRAIGH INSERION SRIP 5/6 IN. (8 MM). Fig. 8. Proper wiring technique.
