Remote Indoor Air Temperature Sensor
Bard Part #8403-062
SAFETY CONSIDERATIONS
Carefully read and follow entire instructions before starting the installation. Follow all local electrical codes
during installation. All wiring must conform to local and national electrical codes. Improper wiring or
installation may damage the controller sensor.
INTRODUCTION
The 8403-062 Remote Indoor Temperature Sensor is a 10k-ohm Type II thermistor, which can be used as
an accessory for use with Bard 8403-060 controller system or the Bard CompleteStat controller series. The
8403-060 can be configured to control using the 8403-062 remote sensor as the only sensor, or to average
the measured temperature at the remote sensor location with the temperature at the controller location.
INSTALLATION
GENERAL REQUIREMENTS:
1. Shielded twisted pair, 22 AWG (or heavier) should be used to avoid possible interference from other electrical systems. The shield (drain) should be connected to 24V Common (C) on the controller end.
2. The sensor comes with a cover and mounting base to mount and protect the remote indoor sensor.
3. Select the exact mounting location and route a 2-conductor interconnecting wire between the remote indoor sensor and the 8403-060 controller location.
4. Terminate the interconnection wiring at the 2 screw terminals on the remote indoor sensor. See Figure 1 for 8403-060 connection and Figure 2 for CompleteStat connections.
5. The termination point at the controller will be GND and ID terminals at the right side of the controller subbase. Sensor polarity is not important.

Testing Completed Wiring
When the 8403-062 sensor is
properly connected, the 8403060 controller will recognize
the sensor connection, and
automatically place Remote
Indoor Sensor selection options in
the Installer menu.
