(7) OPTIONAL – INSTALL AN AUTOMATIC HUMIDIFIER CONTROL (AHC)
Note: The AHC uses its own outdoor temperature sensor, which is read by the thermostat. If an AHC is to be installed, do not wire an outdoor temperature sensor to the ODT terminal of the thermostat.
1. Mount the AHC and its outdoor temperature sensor.
•Follow the directions provided with the AHC except do not mount the AHC temperature sensor in a fresh air intake. The temperature sensor must be mounted outside.
•Maximum wire length from AHC to thermostat is 300 feet.
•The AHC must have constant power. DO NOT power the
AHC through furnace accessory terminals.
•DO NOT operate the AHC in Manual Mode – this will result in the outdoor temperature shown on the thermostat to always be 20°F.
2. Run a
CAUTION

3.Wire the AHC to the thermostat (see Figure 8).
• Strip 1/4" of insulation from the ends of the wires.
•Connect the I- terminal of the AHC to the I- terminal of the thermostat.
•Connect the I+ terminal of the AHC to the I+ terminal of the thermostat.
4.You will need to power up the thermostat to verify the connection. Refer to step 5 of THERMOSTAT START UP on page 24.
5.After completing the thermostat installation, you will also need to verify proper operation of the AHC – see AHC installation instructions for details on how this is done.
