Scrolling Marquee -- This device is the keypad imerface used to access the control information, read sensor values, and test the unit. The Scrolling Marquee is located in the main control box and is standard on all units. The Scrolling Marquee display is a 4-key, 4-character, 16-seglnent LED (light-emitting diode) display module. The display also contains an Alarm Stares LED. See Fig. 1.
System PilotTM Device -- The System Pilot (33PILOT01) device is a component of Ca_cier's 3VTM system and serves as a user-interface and confimlration tool for all Carrier communicating devices. The System Pilot device can be used to install and commission a 3V zoning system, linkage compatible air source, universal controllei; and all other devices operating on the Canier comlnunicating network.

SERVICE Control Configuration ChecklistRefer to checklist CL- 1 for recording site specific unit control configurations. The Service Test function can be used to verify proper operation of compressors, heating stages, indoor tan, outdoor finis, power exhaust tans, economizer, and atann relay. Use of Service Test is recommended at initial system start up and during troubleshooting. See Table 36.

IAQ Switch -- For units with the economizer option or accessory and the ECB control board, the IAQ switch input is provided on the field connection terminal board (TB2). The IAQ Switch Input configuration, Configuration-->AIR.Q --->I!.CEidentifies the nonnatly open or nonnatly closed status of this input when the indoor air quality value is low (good) and also selects the unit response to this input.
Shut Down on IDF Failure (IDF..F) This conli_ration applies only ifa tan switch is installed and configured. A YES value wilt enable diagnostic Alert T409 to shut down the unit when incorrect tan status is sensed. A NO value will still permit Alert T409 but will not cause unit shutdown. The factory default value is YES. Economizer Installed (ECEN) This confimlration identifies if an economizer is installed. A YES value enables economizer operation. A NO value disables economizer operation.
Indoor Fan -- The indoor thn is controlled by the indoor tan relay output (Outputs--->FA?_i9--->IDF)on the MBB (main base board) control, wNch then operates the indoor tan contactor. The indoor fan may operate during cooling with compressors mode, fiee cooling with outdoor air mode, heating mode, or for ventilation with outdoor air mode. ensure proper time delays and SAT control when the economizer is cooling. Cooling begins when the Y1 input is energized.
Two methods are used to add and relnove stages of cooling for units with more than one compressor. The first method causes the unit to operate around its steady-state number of stages. For example, if the correct number of stages is between 0 and 1, this method wilt cause the first stage to cycle. If the correct number of stages is between 1 and 2, this method will cause the second stage to cycle. The second method causes the unit to find the steady-state nulnber of stages.
If theindoor tancontrol isconfigured tocyclewiththeheating demand ((bnfiguration---_UNIr_OC.FN = No) the is satisfied, the MBB will mm off HT. 1 which will turn off gas to the main burners. thn will stop after a conligured delay, (bnfiguration---_ HEAT---_FOD.G Factory dethutt value is 45 seconds. If the IGC temperature limit switch opens within 10 minutes of the end of the gas heating, the next thn off delay wilt be extended by 15 seconds. The maximum delay is 3 minutes.
The control uses rvvomethods to add a stage of heating. The first method will add a stage of heating when the Heating Demand (Operating Modes-+HEAT---aqPT-+ DMD.H) plus the change in heat demand (Operating Modes -+HEAT_SPT-+TRD.H) times the Heat Thermal Lag Factor (Operating Modes-+HEAT---)_7PT-+H.LAG) is greater than the SPT Heat Demand (+) Level (Operating Modes-+ HEAT---_qPT -+HT..PD ). DMD.H + TRD.H * H.LAG > HT..PD indoor tan wilt follow the HT. 1 output.
SPACE SENSOR CONTROL If theunitis in cooling, operating underspace tcnnperature control, theeconomizer is available forcooling, andnocompressors areoperating, the economizer willcontrol theSATtoeither Setpoints--->LCgP or Free Cooling ((bnfiguration--+E_DN--+UEFC), Free Cooling Preoccupancy Time (Configuration--_E(ON--_FC.

Loosen tan motor bolts. Verify Sensor Performance -- Verit) that thermistor, transducer, and switch inputs (see Tables 50-52) are reading correctly. These values can be accessed through the Scrolling Marquee display in the Temperatures, Pressures, and Inputs menus.
TO USE THE COOLING CHARGING CHART, STANDARD UNITS Use the above temperature and pressure readings, and find the intersection point on the cooling chaNing chart. If intersection point on chart is above line, add refiigerant. If intersection point on chart is below line, carefully recover some of the charge. Recheck suction pressure as charge is adjusted.
Recovery cylinder service pressure rating must be 400 psig. Puron systems should be charged with liquid refiigerant. Use a comlnercial-type metering device in the manifold hose. Manifold sets should be 750 psig high-side and 200 psig low-side with 520 psig tow-side retard. Use hoses with 750 psig selwice pressure rating. Leak detectors should be designed to detect HFC refiigerant.
10. Lift bumer/mmlifold assembly out of unit. CLEANING AND ADJUSTMENT 1. Relnove burner rack tiom unit as descTibed in Main Burner Relnoval section above. Main Burners (48PG Only) -- For all applications, main burners are ti_ctory set and should require no adjustment. MAIN BURNER REMOVAL 1. Shut off (field-supplied) lnanual main gas vatve. 2. 3. 4. 5. 6. 2. Inspect burners, and if dirty, remove burners tiom rack. 3. Using a soft brush, clean burners and crossover port as required. 4. Adjust spark gap.
Filter Drier -- Replace whenever ref-igerant system is exposed to atmosphere. Only use factory specified liquid-line tilter driers with working pressures no less than 650 psig. Do not install a suction-line ftter drier in liquid line. A liquid-line flter drier designed for use with Puron,_R)refi-igerant is required for ca& circuit. Fuses are also located in the control box and teed power to the condenser fan motors. Always replace blown fuses with the correct size fuse as indicated on the unit fuse label.
