screw. See Fig. 8.
3. Securely tighten each screw.
4. Push excess wire back into the hole.
5. Plug the hole with nonflammable insulation to prevent drafts from affecting the thermostat.

NOTES:
1. When used in a single-transformer system, leave metal jumper wire in place between RC
and R. If used on a two-transformer system, remove metal jumper wire between RC and R.
2. Common wire is optional when thermostat is used with batteries.
3. If thermostat is configured for a heat pump system in the Installer Setup, configure
changeover valve for cool (O-factory setting) or heat (B).
4. The “L” terminal is an input (system monitor) when the System mode is in the HEAT, OFF,
COOL or AUTO position. When using the “L” terminal connect the 24 VAC Common. See LCD

·there is good air circulation.
·it can measure true outdoor ambient temperature.
·there is a flat surface.
·maximum distance between outdoor sensor and touchscreen thermostat is 65 ft (20m).
See fig 20.
Do not mount the sensor
·in direct sunlight.
·where hot or cold air blows on the sensor. Discharge line from an outdoor compressor
unit, vent or fan causes inaccurate temperature readings.
·where snow, ice or debris can cover it.
Use the following steps to mount the sensor:
1. Remove the sensor from the mounting clip.
2. Mark the area on the location selected for mounting the sensor mounting clip.
3. Mount the clip.

CAUTION- OUTDOOR SENSOR
Electrical Interference (Noise) Hazard.

Erratic temperature readings from a sensor can occur as a result of any of the
wiring practices that are not to local and national electrical standards. Follow
wiring these practices to assure correct operation. Use shielded cable to reduce

CAUTION- OUTDOOR SENSOR
Electrical Shock Hazard.
Can cause electrical shock or equipment damage.
Disconnect power supply before connecting wiring.
Wiring must comply with local and national codes, ordinances and regulations:
1. Wire Outdoor Sensor to S1and S2 terminals on the thermostat. If leadwire provided is not
long enough, you need an extra cable to reach the hole at maximum distance between the
outdoor sensor and the touchscreen thermostat is 65 ft.
a. Using color-coded, 18-gauge thermostat wire is recommended. For example of general
wiring of sensor, see Fig. 21.
b. Pigtail wiring can be used.
2. Mount Sensor in its mounting clip.
3. Plug wiring hole using non-hardening caulk or putty.
