BAC-1xx63 Series (6 Relays, 3 Analog Outputs)

Installation Guide

STE-1451 Outside Air Temp. Sensor

STE-1416 Duct Averaging Temp. Sensor

MEP-5372/7252/7552/7852 Fail-Safe Actuators

XEE-6311-075 or XEE-6311-100 Transformer

IF BOTH RC AND RH TERMINALS ARE PRESENT:
WIRE RC TO SC 1-3 AND RH TO SC 4-6.

IF ONLY ONE “R” TERMINAL IS PRESENT:
WIRE BOTH SC 1-3 AND SC 4-6 TO R.

CSE-1102 Air Differential

Pressure Switch

NOTE: EITHER FAN STATUS (FST) OR

DISCHARGE AIR TEMP (DAT) CAN
BE USED ON IN2, BUT NOT BOTH.

2 Heat and 1 or 2 Cool

NOTE: Terminal connections and menus

reflect firmware version R1.3.0.4 or

later. (Relay 3 and 4 were swapped in

versions earlier than R0.0.0.0.)

*When using optional Outside Air Damper, must also have MAT/OAT

inputs (typically 10K, Type III thermistors). Ensure pull-up resistor

switch positions are set properly—see Illustration 3 on page 2.

**Fan Status (FST) or Discharge Air Temperature (DAT) is an optional,

selectable input. Ensure pull-up resistor switch positions are set

properly (10K position) for the relay, switch, or Type III thermistor.
