OUTDOOR SENSORS (Optional Accessory) - One wired or wireless
See the Outdoor Sensor instructions for further details.
Outdoor sensor can be installed to read the outdoor temperature. To
view this sensor, press and hold the MODE button for two seconds.
Press any button to exit the outdoor temperature display.
The Outdoor Sensor measures outdoor air temperature and sends this
information to the thermostat; it measures temperature with a range of
-40 to 127 F.
The Outdoor Sensor should be connected to the
thermostat using solid conductor CAT 5, CAT 5e,
or CAT 6 type network communication cable. This
is an unshielded cable with four twisted pairs of
24 gauge solid wire; DO NOT use stranded cable.
The cable length should not exceed 250 feet. If
less than 75 feet of cable is required to connect
the thermostat to the Outdoor Sensor, a three
conductor thermostat cable (18-24 gauge) may
be used; this cable is NOT suitable for any length
greater than 75 feet.
IMPORTANT: Do no use shielded wire. Do not run
run sensor wiring in the same conduit as the
24VAC thermostat wiring. Electrical interference
May cause the sensor to give incorrect temperature readings.
