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 ORANGE WIRE F
ROM 240 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.
FOR 3-WIRE VENT MOTOR; IF SUPPLY POWER IS 208V,
DISCONNECT RED VENT MOTOR WIRE LEAD FROM
RED VMC - T2 WIRE EXTENSION. CONNEC
T 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.
