Carrier 50XJ064-104 specifications Space Temperature Sensor Typical Wiring 33ZCT55SPT

AIR TERMINALS AND FRESH AIR DAMPER (50XJ PCB2) — The VAV Terminal Open (TRMOP), Ventilation Output (VENTR), VAV Terminals Control (TRMCT), and Heat Interlock Relay (HIR) terminals provide dry contacts to command the VAV terminals open; a ventilation damper open; VAV terminals to control to their cooling set points; and VAV terminals to control to their heat set points, respectively.

REMOTE OCCUPANCY (ROCC) (TB2 50BV, TB6 50XJ) — The 50XJ,BV unit may be commanded by a remote control system or a twist timer to become occupied and run when a set of dry contacts close. In order for this to occur, wire the contacts to ROCC and C.

SMOKE DETECTOR/FIRE ALARM SHUTDOWN (FSD) (TB2 50BV, TB6 50XJ) — To allow a smoke detector to shut the 50XJ,BV unit down, remove the jumper from FSD to C and wire these terminals to a set of normally closed contacts on the smoke detector.

ALARM (ALARM) AND WARNING (WARN) OUTPUTS (TB2 50BV, TB6 50XJ) — Two dry contacts output a dis- crete signal when the alarm and warning lights on the display are lit. To pick up the alarm output signal, wire between the ALARM and ALM-CM terminals. To pick up the warning output signal, wire between the WARN and ALM-CM terminals.
