(9)OPTIONAL – INSTALL AN APRILAIRE MODEL 8051 FLUSH MOUNT OR 8053 SURFACE MOUNT TEMPERATURE SENSOR
Figure 10 |
1.Mount the indoor temperature sensor.
•Locate the sensor as you would locate a thermostat.
•Maximum wire length from sensor to thermostat is 300 feet.
•Follow the installation instructions provided with the sensor.
2.Run a

side line voltage (120 VAC) or higher lines as this can cause erratic readings.
3.Take a resistance measurement before connecting to the IDS and CIR GND terminals to verify the sensor is properly installed.
•Use an ohmmeter to measure the resistance (kΩ) of the sensor. The resistance reading will depend on the indoor temperature (see table from OUTDOOR SENSOR installation section on page 20).
4.Wire the sensor to the thermostat (see Figure 10).
•Strip 1/4" of insulation from the two sensor wires.
•Connect the sensor wires to the IDS and CIR GND terminals of the thermostat. The wiring is not polarity sensitive, so either wire can be connected to either thermostat terminal.
