Introduction

The indoor sensor is designed to sense the air temper-

ature at a remote location and send this information to

the thermostat. Once connected, the thermostat

responds only to the temperature sensed by the

indoor sensor(s) or by averaging the reading between

the thermostat and the remote sensor.

Installation of Indoor Sensor

11. Install the thermostat according to the instruction

manual supplied with it. Check that the thermostat

is operating. (Display shows the correct

temperature.) CAUTION: Remove the thermostat

from the subbase while wiring the sensor to

avoid damage from live wires. This is important.

12. Install shielded or nonshielded two wire twisted

cable from the thermostat to the remote sensor

location. Maximum distance is 330 ft. (100m).

13. Open the sensor case by grasping the side and

pulling the two halves apart.

14. Use the subbase as a template to mark the

mounting hole locations on the wall. Drill size for

the wall anchors is 1/4 inch. Mount the subbase

over the wires coming out of the wall using the two

screws and anchors provided. Do not use hex

head screws.

15. Strip 1/4 inch of insulation from the two wires at

the remote sensor. Install the wires in the

terminals. The wires can be connected with

either polarity. Seal the hole in the wall around

the cable to eliminate any draft that might affect

the sensor.

16. Connect the wires on the thermostat subbase to

the sensor terminals. Again, the wires can be

connected with either polarity. Connect the wires

to the terminal labeled “Indoor Sensor”.

17. Mount the thermostat on the subbase and check

to be sure that it is showing the temperature.

Temperature Averaging

When a remote indoor

sensor is connected to the

thermostat, the thermostat

will recognize the sensor.

To activate the sensor,

press MENU.

Press the DOWN key to high-

light SENSOR SELECT.

Press SELECT.

Using the UP and DOWN

keys, select USE LOCAL

SENSOR, AVERAGE LOCAL/

REMOTE, or USE REMOTE

SENSOR.

If USE LOCAL SENSOR is chosen, the thermostat will

control the temperature sensed by the sensor built into the

thermostat.

If AVERAGE LOCAL/REMOTE is chosen, the thermostat will

control the temperature based on the average of the local

sensor and the remote sensor.

If USE REMOTE SENSOR is chosen, the thermostat will con-

trol the temperature sensed by the remote sensor.
