REPLACEMENT WIRE MUST BE SAME SIZE AND TYPE OF INSULATION AS ORIGINAL (AT LEAST
105° C). USE COPPER CONDUCTORS ONLY. USE N.E.C. CLASS 2 WIRE FOR ALL LOW VOLTAGE
FIELD CONNECTIONS.
REFERENCE DAIKIN ACCESSORY WIRING DIAGRAM BOOKLET AND/OR INSTALLATION MANUAL
FOR WIRING OF OPTIONAL EQUIPMENT.
TR PRIMARY (HIGH VOLTAGE) CONNECTIONS: ORANGE WIRE CONNECTED TO 240V TAP AT THE
FACTORY AND BLACK WIRE TO COM TERMINAL. FOR 208V SUPPLY POWER, MOVE ORANG
E WIRE
FROM 240V TAP TO THE 208V TAP.
G (BLACK) BLOWER SPEED IS FACTORY WIRED TO T1. Y1 (YELLOW) AND Y2 (PURPLE) BLOWER
SPEEDS ARE FACTORY WIRED TO T1 AND T4 RESPECTIVELY. W1 (WHITE) AND W2 (BROWN)
BLOWER SPEEDS ARE FACTORY WIRED TO T2 AND T3 RESPECTIVELY. IF DIFFERENT SPEEDS ARE
NEEDED, SEE IO MANUAL FOR FURTHER DETAIL ON BLOWER SPEED TAPS.
IF REFRIGERANT LEAK DETECTION PCB IS INSTALLED, REMOVE ES-PLM PLUG (WITH PINK WIRE)
AND CO
NNECT IT TO RDS-PLF1. THEN, CONNECT RDS-PLM2 TO ES-PLF. REMOVE BM-PLM3 AND
CONNECT LR-PLM TO BM-PLF3.
FOR 3-WIRE VENT MOTOR; IF SUPPLY POWER IS 208V, DISCONNECT RED VENT MOTOR WIRE
LEAD FROM RED VMC - T2 WIRE EXTENSION. CONNECT THE BLACK VENT MOTOR WIRE LEAD TO
THE RED VMC - T2 WIRE EXTENSION. CONNECT THE RED VENT MOTOR LEAD TO THE BLACK IIC -
UNUSED WIRE EXTENSION.
