For proper operation, the remote indoor temperature/humidity sensor must be configured properly with the controller.
An additional remote indoor temperature-only sensor can be purchased and installed in Zone 1. Also, temperature
and humidity sensors can also be purchased and installed in Zones 2 and 3 (one per zone). For information on
remote indoor sensor configuration, see page 26. For each additional sensor installed, be sure to enable the sensor
in the controller menus (see Configure Sensors beginning on page 40).
Additional Remote Temperature and Temperature/Humidity Sensor Installation
One additional temperature sensor can be added to Zone 1 and additional temperature/humidity sensors may be
added to Zones 2 and 3 (one per zone). Be sure the sensors are connected to the proper terminals on the terminal
block and sensor as listed below.
