INSTALLATION

On some units, the Outdoor Ambient Temperature (OAT) and Outdoor Coil Temperature (OCT) sensors may be attached permanently to the controller. The 47D43-811 includes replacement OAT and OCT sensors that plug onto the 2- and 3-pin connectors on the controller board.

Before removing the old controller, note the location of the OCT sensor on the outdoor coil. The new sensor should be attached to the coil in the same location, or as close as possible. The OAT sensor is typically 24-48” long, although some controllers have the sensor on the board. Placement of the OAT sensor is not as critical as the OCT sensor, but both sensors are required for the controller to operate.

Six metal standoffs, 0.375 inch long, are used to support and mount the control into the unit.

Board size is 3.375 in. x 3.625 in. and requires 1 inch of headroom (not including mounting).

NOTE

All wiring should be installed according to local and national electrical codes and ordinances.

The 47D43-811 control may be mounted on any convenient surface using the six standoffs provided.

The control must be secured to an area that will experience a minimum of vibration and remain below the maximum ambient temperature rating of 150o F. The control is approved for minimum ambient temperatures of -40oF.

Any orientation is acceptable.

Refer to the wiring diagram and wiring table when connecting the 47D43-811 control to other components of the system.

UL approved, 105o C rated 18 gauge min., stranded 2/64” thick insulation wire is recommended for all low voltage safety circuit connections.

UL approved, 105o C rated 16 gauge min., stranded 2/64” thick insulation wire is recommended for all line voltage connections.

Following installation or replacement, follow appliance manufacturer’s recommended installation or service instructions to insure proper operation.
