Outputs
BO1/RLY1 3-Speed Fan Low Speed; Mod. Fan Start
BO2/RLY2 3-Speed Fan Medium Speed
BO3/RLY3 3-Speed Fan High Speed
BO4/RLY4 On/Off Heat/Cool Valve*
BO5/RLY5 On/Off Auxiliary Heat**
BO6/RLY6 Binary Output #6
AO7/OUT7 Modulating Heat/Cool Valve*
AO8/OUT8 Modulating Auxiliary Heat**
AO9/OUT9 Modulating Fan Speed Control
*AO7 and BO4 are controlled simultaneously.
**AO8 and BO5 are controlled simultaneously.
NOTE: For unit ventilator (with outside air
damper) applications, see
Unit Ventilator (BAC-19xx36) on page
12.
NOTE: Binary Output (BO1—BO6) terminals
are relays and are used with SC
terminals instead of GND terminals.
NOTE: Universal (analog) inputs (AIx/INx) and
outputs (AOx/OUTx) are used with GND
terminals. They can be configured to
emulate binary (on/off or voltage/no-
voltage) objects.

Analog Output (AOx) object. Relay
output (RLYx) = Binary Output (BOx)
object.
NOTE: Unused inputs and outputs are
available for use with custom
configuration and programming in
KMC software.
