August 2020 4TWR6048H-SF-1H-EN SAFETY SECTION Important -- This document contains service information. This is customer property and is to remain with this unit. Please return to service information pack upon completion of work. WARNING HAZARDOUS VOLTAGE! Failure to follow this Warning could result in property damage, severe personal injury, or death. Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. WARNING REFRIGERANT OIL! Failure to follow this Warning could result in property damage, severe personal injury, or death. These units use R-410A refrigerant which operates at 5070% higher pressures than R-22. Use only R410A approved service equipment. Refrigerant cylinders are painted a "Rose" color to indicate the type of refrigerant and may contain a "dip" tube to allow for charging of liquid refrigerant into the system. All R-410A systems use a POE oil that readily absorbs moisture from the atmosphere. To limit this "hydroscopic" action, the system should remain sealed whenever possible. If a system has been open to the atmosphere for more than 4 hours, the compressor oil must be replaced. Never break a vacuum with air and always change the driers when opening the system for component replacement. For specific handling concerns with R-410A and POE oil, reference Retrofit Bulletin TRN-APG02EN. CAUTION HOT SURFACE! May cause minor to severe burning. Failure to follow this Caution could result in property damage or personal injury. Do not touch top of compressor. CAUTION CONTAINS REFRIGERANT! Failure to follow proper procedures can result in personal illness or injury or severe equipment damage. System contains oil and refrigerant under high pressure. Recover refrigerant to relieve pressure before opening system. ©2020 Trane CAUTION GROUNDING REQUIRED!

(i) The outdoor condensing units are factory charged with the system charge required for the outdoor condensing unit, ten (10) feet of tested connecting line, and the smallest rated indoor evaporative coil match. Always verify proper system charge via subcooling (TXV/EEV) or superheat (fixed orifice) per the unit nameplate. 4TWR6048H-SF-1H-EN 3 Wiring 4 4TWR6048H-SF-1H-EN Wiring 4TWR6048H-SF-1H-EN 5 Subcooling Charging in Cooling between 55° F and 120° OD Ambient Trane has always recommended installing Trane approved matched indoor and outdoor systems. The benefits of installing approved indoor and outdoor split systems are maximum efficiency, optimum performance and the best overall reliability. The following charging methods are therefore prescribed for matched systems with indoor TXVs / EEVs. (Systems can be rated with TXV, EEV or Piston. Ensure charging method is correct). 1. Subcooling (in the cooling mode) is the only recommended method of charging above 55° ambient temperatures. 2. For best results the indoor temperature should be kept between 70° to 80° F. Add system heat if needed. 3. At startup, or whenever charge is removed or added, the system must be operated for a minimum of (20) minutes to stabilize before accurate measurements can be made. 4. Measure Liquid Line Temperature and Refrigerant Pressure at service valves. 5. Determine total refrigerant line length, and height (lift) if indoor section is above the condenser. 6. Determine the Design Subcooling Charging Temperature from the unit nameplate. 7. Locate this value in the appropriate column of the Subcooling Charging Table. Locate your liquid line temperature in the left column of the table, and the intersecting liquid line pressure under your nameplate subcool value column. Add refrigerant to raise the pressure to match the table, or remove refrigerant to lower the pressure. Again, wait (20) minutes for the system conditions to stabilize before adjusting charge again. 8. When system is correctly charged, you can refer to System Pressure Curves to verify typical performance.

Weigh-In Method can also be used when power is not available to the equipment site or operating conditions (indoor/ outdoor temperatures) are not in range to verify with the subcooling charging method. Calculating Charge Using the Weigh-In Method STEP 1 - Measure in feet the distance between the outdoor unit and the indoor unit. (Include the entire length of the line from the service valve to the IDU.) Subtract 10 ft from this entire length and record on line 1. STEP 2 - Enter the charge multiplier (0.6 oz/ft). Each linear foot of interconnecting tubing requires the addition of 0.6 oz of refrigerant. 1. Total Line Length (ft) 10 ft 2. Charge multiplier x 0.6 oz STEP 3 - Multiply the total length of refrigerant tubing (Line 1) times the value on Step 2. Record the result on Line 3 of the Worksheet. STEP 4 - This is the amount of refrigerant to weigh-in prior to opening the service valves. 3. Step 1 x Step 2 4.

A second sensor located on the outdoor coil is used to measure the coil temperature. The difference between the ambient and the colder coil temperature is the difference or delta-T measurement. This delta-T measurement is representative of the operating state and relative capacity of the heat pump system. Measuring the change in delta-T determines the need for defrost. The coil sensor also serves to sense outdoor coil temperature for termination of the defrost cycle. Fault Detection A fault condition is indicated by the flashing Fault LED light on the defrost control board located inside the heat pump control box. In normal operation, the status LED will flash once each second when idle or twice each second with a call for heating or cooling. PIN Identification 1. TEST_COMMON (Shorting any of the other pins to this pin causes the function of the other pin to be executed. Leaving this pin open results in the normal mode of operation). 2. FRC_DFT = Forced Defrost (Short TEST_COMMON to this pin speeds up all defrost. Remove the short after defrost initiates. Defrost Control Checkout Normal operation requires: a. Status LED on board flashing 1 time/second in standby or 2 times/second with a call for heating or cooling. b. 24V AC between R & B c. 24V AC between Y, Y0 & B with unit operating d. Defrost initiation when FRC_DFT pin is shorted to TEST_COMMON pin. 158286B D Test Sensors Measure the temperature the subject sensor is exposed to. If the sensor is mounted on a tube, place the lead on an Annie A-8 (or equiv.) temperature tester on the same tube near the sensor and insulate the bulb. Unplug the sensor and measure the resistance with a good quality ohmmeter (Simpson 260 or equiv.). Read the value as quickly as possible to prevent the meter current from changing the resistance reading. Using the chart, locate (as close as possible) the actual sensor temperature. The measured resistance should be relatively close to the resistance value shown in the chart. 8 4TWR6048H-SF-1H-EN Table 1.

LED FAULT CODES LED FAULT CODES FAULT DESCRIPTION DEFROST CONTROL BEHAVIOR 1 FLASH Ambient Temp Sensor is out of range (open/shorted) Initiate defrost after every 60 minutes of runtime. Defrost will terminate on coil temp. See Note 1 & 2. 2 FLASH 3 FLASH Coil Temp Sensor is out of range (open/shorted) Initiate a 15 minute forced defrost after every 60 minutes of runtime. See Note 1 & 2. Low Pressure Switch is open 3 flash goes away when/if LPCO closes. 4 FLASH Hard Lock Out (can only be cleared with a low voltage power cycle) Occurs after 9th trip of LPCO. See Note 6. 9 Defrost Control Table 3. LED FAULT CODES (continued) LED FAULT CODES FAULT DESCRIPTION DEFROST CONTROL BEHAVIOR 5 FLASH Soft Lock Out 5 flash goes away after soft lockout period expires. See Note 2. Defrost cycles too close 6 FLASH together Heating short cycle fault triggers 6 flash. The system will follow 10 adaptive time heating cycles and then return to demand defrost. 9 FLASH Low Ambient Soft Lockout. Outdoor temperature dropped below 3°F. (OFF at -12°F/ON at 3°F) Outdoor temperature is below -12°F. See Note 5. 1. Initiate Adaptive/Timed Limp Mode so long as Coil Temp Sensor is functional. Monitor actual time in defrost and add or reduce run time until next forced defrost based on achieving a 4 minute (+/-1) defrost period. 2. This defrost control utilizes a safety strategy called "Adaptive Limp Mode". Adaptive limp mode is defined as a timed heating mode following rapid defrosts (accumulated heating times between defrost totaling less than 15 minutes). Once invoked the DFC will limit defrost periods and maximize heating capacity. While in adaptive limp mode the DFC will monitor heating and defrost periods for no longer than 10 cycles. The DFC will then release the board to demand defrost; however, if the LPCO trips while in limp mode the system will initiate a soft lockout and exit limp mode. If both Coil Temp Sensor and Ambient Temp Sensor have failed, initiate a 5 minute forced defrost every 60 minutes of run time. This in conjunction with the normal low pressure trip, will initiate a soft lockout. a. A short heating cycle that enters defrost in 15 minutes or less and/or enters two more defrosts with less than 15 minutes of accumulative run time each will enter an Adaptive Limp Mode (6 Flash). b. Coil sensor failure will initiate a Timed Limp Mode. This will be accompanied by a 2 flash. The DFC will initiate defrost after 60 minutes of accumulated heating runtime and terminate after a 5 minute defrost. The limp mode will clear after the sensor fault is cleared. c. Ambient sensor failure will initiate an Adaptive Timed Limp Mode. This will be accompanied by a 1 flash. The DFC will initiate defrost after 60 minutes of accumulated heating runtime and force a defrost, which will terminate on coil 10 temp. The limp mode will clear after the sensor fault is cleared. d. This could be caused by a condenser fan motor failure, low charge or other reasons. 3. The first 15 minute soft lockout the system will return to normal operation. Should this continue to operate in this manner there will be a 30 minute soft lockout and so on. At the end of the lockout process, if a hard lock is necessary, a 4 flash will be announced and system operation is interrupted. If the ambient temperature climbs above 40°F for more than 30 minutes this clears this fault count and resumes normal operation. a. If or when normal operation is restored after the ambient temperature climbs above 40°F for more than 30 minutes and another LP trip is monitored on the 9th trip this will initiate a hard lockout that will not be cleared by temperature or time. 4. Once ambient drops to -12 or lower wait 5 minutes before soft lockout begins. During soft lockout the Y signal passes through to the X2 output. Resume operation when ambient temperature rises to -3°F or higher and after 5 minute soft lockout period expires. LPCO should reset around 5°F. 5. During a Hard Lockout, the X2 relay opens so that the Y signal does not pass through.
