208-230/60/1, Unit Sizes 036, 048, 060 and 072
FIELD POWER SUPPLY PER UNIT RATING PLATE. MINIMUM CIRCUIT AMPACITY AND
MAXIMUM SIZE OF TIME-DELAY FUSE OR HACR-TYPE CIRCUIT BREAKER PER UNIT
RATING PLATE. PROVIDE DISCONNECTING MEANS AND EQUIPMENT GROUNDING AS
REQUIRED.
TRANSFORMER MAY HAVE TAPS FOR 120V, 208V, 240V, OR 480V SYSTEM POWER
SUPPLY. BEFORE APPLYING POWER TO THE UNIT, ENSURE TRANSFORMER IS WIRED
FOR APPROPRIATE SYSTEM POWER SUPPLY. INSULATE SEPARATELY ANY UNUSED
LEADS. POLARITY IS NOT INDICATED. TYPICAL TRANSFORMER SHOWN. SEE
TRANSFORMER LABEL FOR LEAD COLOR CODING.
“RVS” IS USED ONLY WITH WWR MODELS AND IS ENERGIZED IN COOLING MODE (LOAD
COIL IS HEAT SOURCE, SOURCE COIL IS HEAT SINK).
“RVS” IS NOT USED WITH WWC AND WWH MODELS.
IF POWER MONITOR OUTPUT CONTACTS DO NOT TRANSFER WHEN POWER IS APPLIED
TO UNIT (BICOLOR LED GLOWS GREEN UNDER NORMAL CONDITIONS AND RED
DURING FAULT CONDITIONS):
1. VERIFY THAT ALL THREE PHASES ARE PRESENT AND ARE OF THE CORRECT
VOLTAGE. IF ALL THREE PHASES ARE PRESENT AND ARE OF THE CORRECT VOLTAGE,
PHASE ROTATION MAY BE INCORRECT. PERFORM STEP 2.
2. DISCONNECT POWER TO THE WW* UNIT. VERIFY THAT POWER IS IN FACT
DISCONNECTED. SWAP ANY TWO OF THE THREE UNIT POWER SUPPLY WIRES. WHEN
POWER IS REAPPLIED, OUTPUT CONTACTS SHOULD NOW TRANSFER.

14 WHEN “FS-L” AND “FS-S” ARE NOT USED, THIS WIRE CONNECTS DIRECTLY TO
TERMINAL Y OF “CCM”.
WHEN “PM” IS NOT USED, THIS WIRE CONNECTS DIRECTLY TO TERMINAL R ON “TB1”.
4
THIS WIRE CONNECTS DIRECTLY FROM TERMINAL S TO TERMINAL Y ON “TB1” WHEN
OPTIONAL TEMPERATURE CONTROLLER “TC” IS NOT FURNISHED.
HEAT RECOVERY OPTION:
FIELD INSTALLED WASTE HEAT RECOVERY PUMP WIRING. USE 14 AWG, 75C
CONDUCTORS MINIMUM . COMPLY WITH LOCAL CODES WHICH MAY REQUIRE
LARGER SIZE WIRING. INSTALL ADDITIONAL DISCONNECTING MEANS WHERE
REQUIRED TO COMPLY WITH ELECTRICAL CODE. THIS EQUIPMENT MUST BE
PERMANENTLY GROUNDED IN ACCORDANCE WITH ELECTRICAL CODE. TERMINAL
BOARD “TB4” IS RATED FOR BOTH 14 AND 12 AWG WIRE SIZES.
THE FOLLOWING COMPONENTS ARE USED ONLY WHEN WASTE HEAT RECOVERY
(DESUPERHEATER) OPTION IS FURNISHED: “F1”, “F2”, “HRPR”, “PCT”, “TB4”, “WHR”,
AND “WTL”. “WHR” IS ORDERED SEPARATELY FOR FIELD INSTALLATION.

TYPICAL FIELD CONTROL WIRING SHOWN. ACTUAL FIELD WIRING MAY DIFFER FROM
WIRING SHOWN HERE. USE 18 AWG MINIMUM FOR FIELD 24 VOLT CONTROL WIRING.
TYPICAL REMOTE SWITCH SHOWN. REMOTE SWITCH MAY BE SUPPLIED BY OTHERS
OR IS AVAILABLE AS AN OPTIONAL ACCESSORY FROM THE FACTORY. MINIMUM PILOT
DUTY RATING OF EACH POLE OF REMOTE SWITCH IS 24 VOLT-AMPERES @ 24 VOLTS
AC WHEN CONNECTED AS SHOWN.
AQUASTATS “TS-H” AND “TS-C” ARE NOT USED WHEN OPTIONAL FACTORY INSTALLED
TEMPERATURE CONTROLLER “TC” IS FURNISHED. TYPICAL AQUASTATS SHOWN.
AQUASTATS MAY BE SUPPLIED BY OTHERS OR ARE AVAILABLE AS AN OPTIONAL
ACCESSORY FROM THE FACTORY. MINIMUM PILOT DUTY RATING OF EACH POLE OF
AQUASTAT IS 24 VOLT-AMPERES @ 24 VOLTS AC WHEN CONNECTED AS SHOWN.

16 CONDUCTOR “O” REQUIRED WITH WWR REVERSE CYCLE UNITS.
CONDUCTOR “O” NOT USED WITH WWC COOLING AND WWR HEATING UNITS.
INTERLOCK RELAY CONTACTS ARE PROVIDED TO OPERATE AN EXTERNAL PILOT DUTY
LOAD (SUCH AS A PUMP RELAY COIL) WITH A CALL FOR COMPRESSOR.
AN EXTERNAL LOAD POWERED BY TRANSFORMER “TR” IN THE WW* UNIT MUST
NOT EXCEED 12 VA SEALED (96 VA INRUSH) @ 24 VOLTS AC.
EXTERNAL LOADS POWERED FROM AN EXTERNAL SOURCE ARE LIMITED TO
CLASS 2 CIRCUITS ONLY (30 VOLTS AC MAXIMUM). EXTERNAL LOAD
CHARACTERISTICS MUST NOT EXCEED 10 AMPS MAKE, 1 AMP BREAK. MAINTAIN
SEPARATION BETWEEN CLASS 2 CIRCUITS OF DIFFERENT SOURCES.
PROVIDE DISCONNECTING MEANS, EQUIPMENT GROUNDING, AND
OVERCURRENT PROTECTION AS REQUIRED.
