Figure 1.13 Additional Remote Sensor Installation; Optional Remote; Temperature/Humidity Sensor - Bard W48A2PQ Installation And Service Instructions Manual

For proper operation, the remote indoor temperature/humidity sensor must be configured properly with the
controller. If only the single remote indoor temperature/humidity sensor supplied with the controller is installed, the
configuration setting is "0". This is the default setting. 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 section on additional
sensors beginning on page 46.
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
