As part of the ClearControl™ system which allows real time moni-toring and communication between rooftop units, the RLKN-CPackage Air Conditioner has a Rooftop Unit Controller (RTU-C)factory mounted and wired in the control panel. The RTU-C is asolid-state microprocessor-based control board that providesflexible control and extensive diagnostics for all unit functions.The RTU-C through proportional/integral control algorithms per-form specific unit functions that govern unit operation in responseto: zone conditions, system temperatures, system pressures,ambient conditions and electrical inputs. The RTU-C features a 16 x 2 character LCD display and a five-button keypad for localconfiguration and direct diagnosis of the system. New featuresinclude a clogged filter switch (CFS), fan proving switch (FPS),return air temperature sensor (RAT), discharge air temperaturesensor (DAT) and outdoor air temperature sensor (OAT). Freezesensors (FS) are used in place of freezestats to allow measure-ment of refrigerant suction line temperatures. The RLKN-CPackage air Conditioner with the RTU-C is specifically designedto be applied in four distinct applications:The RLKN-C is compatible with a third party building manage-ment system that supports the BACnet Application SpecificController device profile, with the use of a field installed BACnetCommunication Module. The BACnet Communication Moduleplugs onto the unit RTU-C controller and allows communicationbetween the RTU-C and the BACnet MSTP network. A zonesensor, a BACnet network zone sensor, a BACnet thermostat orDDC controller may be used to send the zone temperature orthermostat demands to the RTU-C. The BACnet Communica-tion Module is compatible with MSTP EIA-485 daisy chain net-works communicating at 38.4 bps. It is compatible with twistedpair, shielded cables.The RLKN-C is compatible with a third party building manage-ment system that supports the LonMark Space Comfort con-troller (SCC) functional profile or LonMark Discharge Air Con-troller (DAC) functional profile. This is accomplished with a fieldinstalled LonMark communication module. The LonMark
Communication Module plugs onto the RTU-C controller andallows communication between the RTU-C and a LonWorksNetwork. A zone sensor, a LonTalk network zone sensor, or aLonTalk thermostat or DDC controller may be used to send thezone temperature or thermostat demands to the RTU-C. TheLonMark Communication Module utilizes an FTT-10A free topol-ogy transceiver communicating at 78.8 kbps. It is compatiblewith Echelon qualified twisted pair cable, Belden 8471 or NEMALevel 4 cables. The Module can communication up to 1640 ft.with no repeater. The LonWorks limits of 64 nodes per segmentapplies to this device.The RLKN-C is compatible with a programmable 24 volt ther-mostat. Connections are made via conventional thermostatscrew terminals. Extensive unit status and diagnostics are dis-played on the LCD screen of the RTU-C.The RLKN-C is compatible with a zone sensor and mechanicalor solid state time clock connected to the RTU-C. Extensiveunit status and diagnostics are displayed on the LCD screenof the RTU-C.A factory or field installed Comfort Alert® module is available forpower phase-monitoring protection and additional compressordiagnostics. The alarms can be displayed on the RTU-C displayor connected to the “L-Terminal” of a thermostat for notification.The damper minimum position, actual damper position, powerexhaust on/off setpoint, mixed air temperature limit setpoint andDemand Controlled Ventilation (DCV) setpoint can be read andadjusted at the unit controller display or remotely through anetwork connection.The Space CO2 level, mixed air temperature, and EconomizerStatus (Free Cooling Available, Single or Dual Enthalpy) can beread at the unit controller display or remotely through a networkconnection. Economizer Faults will trigger a network Alarm andcan be read at the unit controller display or remotely through anetwork connection.

AirSelection ProcedureRLKN Series
RLKN SELECTION PROCEDURES1. Determine cooling and heating requirements at design
conditions. Example: Total cooling capacity ............61,000 BTUH [17.87 kW] Sensible cooling capacity ......44,000 BTUH [12.89 kW] Condenser entering air ..........95°F [35°C] Evaporator entering air............63°F [17°C] wb/76°F [24°C] db Indoor air flow ........................2100 CFM [991 L/s] External static pressure..........1.0 in W.G.
2. Select unit to meet cooling requirements.Since total cooling is within the range of 6 ton [21.1 kW] unitenter cooling performance from the RLKN073 table, at 95°F[35°C] outdoor temperature, 63°F [17°C] wb entering indoorair, and 2100 CFM [991 L/s]:
Total capacity..........................65,000 BTUH [19.1 kW] Sensible Capacity ..................55,400 BTUH [16.2 kW] Power input ............................5.3 kW
And also, at 76°F [24°C] db indoor entering air, and using the formula at the bottom of the page: Sensible capacity....................48,008 BTUH [14.07 kW]
3. Determine blower speed and power to meet the systemrequirements.At the given external static pressure of 1.0 in W.G., the beltmodel must be selected. Enter the belt drive blower perfor-mance table at 2100 CFM [991 L/s] and 1.0 in W.G. ESP:
RPM....................1100 Watts ..................1025 Drive ..................L
4. Calculate indoor blower BTUH heat effect. BTUH = Watts x 3.413 = 3498
5. Calculate net cooling capacities. Net total cooling = 65,000 – 3498 = 61,502 BTUH [18.02 kW] Net sensible cooling = 48,008 – 3498 = 44,510 BTUH
[13.04 kW]
