3Table 2 — 35L,N Unit WeightsLEGENDDDC — Direct Digital ControlsNOTE: Data is based on the following conditions:1. Unit casing is 22 gage.2. Unit insulation is 1/ 2 -in. thick, 1.5-lb Tuf-Skin 1 Rx dual densityfiberglass.3. Units rated with standard linear flow sensor.WarrantyAll Carrier-furnished items carry the standard Carrier warranty.CONTROL ARRANGEMENTSThe 35L,N dual duct units are offered with a wide variety offactory-mounted controls that regulate the volume of air de-livery from the unit and respond to cooling and heating loadrequirements of the conditioned space. Stand-alone controlswill fulfill the thermal requirements of a given control space.These devices are available in both pneumatic and electronicarrangements. Carrier PIC (Product Integrated Controls) is acommunicating control that is integrated with the buildingsystem. The PIC controls are compatible with the CCN sys-tem. A number of DDC (Direct Digital Controls) controlpackages by others are available for consignment mounting,as indicated.Control offerings are:35(L,N)A: Analog Electronic35(L,N)C: CCN Direct Digital Electronic35(L,N)P: Pneumatic35(L,N)N: None or DDC by othersEach control approach offers a variety of operating functions;a control package number identifies combinations of controlfunctions. The following listings contain the basic functionarrangements for each control offering. Because of the vari-ety of functions available, circuit diagrams, operating se-quences, and function descriptions are contained in separateApplication Data publications. Refer to the specific controlpublication for details.CCN Control ArrangementThe CCN control packages must be used in combination with athermostat. Thermostats are not included in the CCN package.4160: Constant volume dual duct4170: 35N only, variable volume dual duct, constant mini-mum cooling (requires cold deck inlet and total flow probe)4175: 35N only, variable volume dual duct, cooling close-offduring heating (requires hot deck inlet and total flow probe)4180: 35N only, constant ventilation dual duct, Cooling only(requires cold deck inlet and total flow probe)4190: Variable air volume (VAV) with Demand ControlledVentilation (DCV) requires separate CO 2 sensorAnalog Electronic Control ArrangementControl package is pressure independent and includes a stan-dard linear airflow sensor in both the hot and cold inlets forvariable air volume control, 24-volt transformer, control en-closures, and a wall thermostat to match the control type.Variable volume control:2400 — Heating and cooling control, hot and cold inlet sen-sor location (35L,N)2440 — Heating and cooling control, hot inlet and dischargeairflow sensing (35N only)2470 — Heating and cooling control, cold inlet and dischargeairflow sensing (35N only)Direct Digital Electronic Control Arrangement(Field-Supplied)Control packages are field-supplied for factory mounting, un-less otherwise noted. All DDC control arrangements includea standard linear inlet flow sensor, 24-volt transformer andcontrol enclosure.Contact Carrier for details about mounting field-suppliedcontrols.Pneumatic Control ArrangementAll control packages are pressure independent and includestandard linear airflow sensors in both the hot and cold inletsfor variable air volume control or an airflow sensor in one inletand the unit discharge for constant volume control arrange-ments. Thermostats will either be direct acting (DA) or reverseacting (RA), and damper position will be identified as normallyopen (NO) or normally closed (NC).Variable air volume control with inlet air sensing (all units):• 1500 — Multi-function controller, DA-NC cold inlet, NChot inlet• 1501 — Multi-function controller, DA-NC cold inlet,NO hot inlet• 1502 — Multi-function controller, DA-NO cold inlet,NO hot inlet• 1503 — Multi-function controller, DA-NO cold inlet,NC hot inlet• 1504 — Multi-function controller, RA-NC cold inlet, NChot inlet• 1505 — Multi-function controller, RA-NC cold inlet, NOhot inlet• 1506 — Multi-function controller, RA-NO cold inlet,NO hot inlet• 1507 — Multi-function controller, RA-NO cold inlet, NChot inletConstant volume control with hot inlet and discharge airsensing (35N Units):• 1508 — Multi-function controller, DA-NC cold inlet, NChot inlet• 1509 — Multi-function controller, DA-NC cold inlet,NO hot inlet• 1510 — Multi-function controller, DA-NO cold inlet,NO hot inlet• 1511 — Multi-function controller, DA-NO cold inlet, NChot inlet• 1512 — Multi-function controller, RA-NC cold inlet, NChot inlet• 1513 — Multi-function controller, RA-NC cold inlet, NOhot inletUNIT SIZEBASEUNIT(lb)WITHPNEUMATICCONTROLS(lb)WITH DDC ORANALOG CONTROLS(lb)35L4, 5, 6 29 37 477, 8 33 41 519, 10 41 49 5912 51 59 6914 67 75 8516 75 83 9322 129 137 14735N6 31 39 498 42 50 6010 61 69 7912 80 88 9814 98 106 11616 111 119 1291.
