About Advanced Features & Operation

DUCT SENSOR (P/N SEN-700-1) - The

thermostat is programmed from the factory to auto-

matically recognize when a Duct

Sensor is connected (step #10, page

13).

The Duct Sensor measures indoor

air temperature and sends this infor-

mation to the thermostat; it measures

temperature with a range of 32 to

99 F.

The Duct Sensor should be con-

nected 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 Duct Sensor, a two

conductor thermostat cable (16-24 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

sensor wiring in the same conduit as the 24VAC therm-

ostat wiring. Electrical interference may cause the

sensor to give incorrect temperature readings.

See the Duct Sensor instructions for further details.

Note: If a Duct sensor is connected to this ther-

mostat, then the fan should be programmed for

continuous operation (step #5, page 11). This will

provide airflow over the Duct sensor and provide
