wiring diagrams) provided for external super visor y
controls such as building EMS (Energy Management
System). Both of these Enable/Disable circuits must be
closed to “enable” heating operation. If either Enable/
Disable circuit is open for any reason heating operation will
be “disabled.” There is a plug with t wo jumper wires
installed from the factor y in the CCB J7 socket
to enable heating operation when external controls are not
in use.
ser vice note: If a super visor y control(s) is used to
enable/disable heating operation, install field wiring
bet ween the J7 socket on the CCB and a set of “dr y
contacts” on the external control per all applicable building
codes. This is a switching circuit only: DO NOT apply
any external voltage or connect any load (IE: relay coil)
to either circuit.
