REMOTE THERMOSTAT AND LOW VOLTAGE CONTROL CONNECTIONS

REMOTE THERMOSTAT

ALL FRIEDRICH VERT-I-PAK UNITS ARE FACTORY CONFIGURED TO BE CONTROLLED BY USING A SINGLE STAGE HEAT/COOL REMOTE WALL MOUN- TED THERMOSTAT. THE THERMOSTAT MAY BE AUTO OR MANUAL CHAN- GEOVER AS LONG AS THE CONTROL CONFIGURATION MATCHES THAT OF THE VERT-I-PAK UNIT.

TO CONNECT THE WALL-MOUNTED THERMOSTAT:

1.PULL THE DISCONNECT SWITCH.

2.UNSCREW AND REMOVE THE CONTROL BOX PANEL.

3.AFTER SELECTING WHICH SIDE YOU WANT TO RUN YOUR THERMOSTAT WIRE THROUGH, RUN THE WIRES THROUGH THE SIDE HOLE IN THE BOX TO REACH THE CONNECTION TERMINAL FOR THE WIRING.

4.MAKE THE WIRE CONNECTIONS, APPROPRIATELY MATCHING THE WIRES AS SHOWN IN THE WIRING DIAGRAM.

5.ONCE EACH WIRE IS MATCHED AND CONNECTED, THE UNIT IS NOW READY FOR OPERATION.

6.REATTACH THE CONTROL BOX COVER.

DESK CONTROL TERMINALS

THE FRIEDRICH VERT-I-PAK HAS BUILT-IN PROVISIONS FOR CONNEC- TION TO AN EXTERNAL SWITCH TO CONTROL POWER TO THE UNIT. THE SWITCH CAN BE A CENTRAL DESK CONTROL SYSTEM OR EVEN A NORMA- LLY OPEN DOOR SWITCH.

FOR DESK CONTROL OPERATION, CONNECT ONE SIDE OF THE SWITCH TO THE D1 TERMINAL AND THE OTHER TO THE D2 TERMINAL (SEE FIGURE 15). WHENEVER THE SWITCH CLOSES, THE UNIT OPERATION WILL STOP.

THE SMART CENTER ALSO HAS THE ABILITY TO CONTROL A 24VAC RELAY TO ACTIVATE AN AUXILIARY, OR TRANSFER, FAN. THE OUTPUTS ARE LISTED AS F1 AND F2 ON THE CONTROL BOARD.

TO CONNECT THE RELAY, SIMPLY WIRE ONE SIDE OF THE RELAY TO F1 AND THE OTHER SIDE TO F2. ANYTIME THAT THE FAN RUNS, THE TERMINALS WILL SEND A 24VAC SIGNAL TO THE RELAY. THE RELAY MUST BE 24VAC, 100MA OR LESS.

NOTE: THE RELAY AND AUXILIARY FANS MUST BE FIELD SUPPLIED.
