CTE-5202Electronic Room Thermostat w/ LCD DisplayDescription and ApplicationThe KMC CTE-5202 thermostat is a dual-setpoint,analog electronic controller with a digital LCDdisplay for use in many new and replacement roomtemperature control applications. It provides twoindependent electronic PI (Proportional Integral)control loops with heating and cooling setpoints.The thermostat drives two (adjustable span) 0–12VDC analog outputs for control of external devices.The easy to understand LCD display and push buttons enable viewing of current temperature, changing of setpoints, and simple device configuration.The thermostat is typically used with KMC CEP/CSP-4000 and CSP-5000 series of electronic pressureindependent VAV controllers, MEP-4002 proportional electronic actuators in pressure-dependentVAV applications, and VEB-43/46 series proportionalcontrol valves in baseboard and other heating/cooling applications. Application sequences may be selected for the following types of room and terminalunit control: Single-duct pressure-independent VAV terminals,with or without reheat and auxiliary minimumairflow (see Sequence 2 on page 3)(Shownadjustingthe Coolingsetpoint—duringnormaloperation,only roomtemperatureis shown inthe upperright of thescreen)Models Single-duct fan-powered VAV terminals with orwithout reheat using REE-5xxx staging modules(Sequence 1) Dual-duct VAV applications with independentcontrol of heating and cooling outputs (Sequence 3) Proportional heating and cooling applications,such as baseboard heating and chilled beams(Sequence 1 and 3)Common application features for morning warmup, changeover, and unoccupied/night setback areenabled via an external temperature sensor and/orcontact closure provided by a remote building automation system.NOTE:For many examples of new andretrofit applications, see the CTE-5202Applications Guide.Light almondCTE-5202WWhiteFeaturesSingle-duct pressure-dependent VAV terminalswith or without reheat (Sequence 1 for single setpoint or Sequence 2 for dual setpoint and/or aux.minimum) CTE-5202 Large LCD display for easy viewing (or can beblanked if desired) and configurationDisplay room temperature in either degrees Fahrenheit or CelsiusEasy setpoint adjustment via front Up and DownbuttonsHeating and cooling setpoints with three selectable sequencesOutputs configurable to conventional spans between 0 and 12 VDCAdjustable min./max./aux. limits (span), deadband, proportional band, integral, temperatureoffset, setback offset, and changeoverExternal input for changeover sensor and setbackcontactFunctionally replaces most Barber Colman TP81xx, KMC CTE-1x0x/CTE-50xx/CTE-51xx, andother room thermostats with a more contemporary version that includes an LCD display andconfigurable sequences and limits (see CrossReferences on page 4)Specifications and design subject1 to change without notice.

Electronic Room Thermostat with LCD DisplayCTE-5202Installation and Operation GuideInstallationACMounting and WiringThe thermostat must NOT be: Mounted on or near a large thermal mass (e.g.,concrete block wall). Blocked from normal air circulation by obstructions. Exposed to heat sources (e.g., lights, computers,copiers, or coffee makers) or to sunlight (at anytime of the day). Exposed to drafts from windows, diffusers, orreturns. Exposed to air flow through the conduit (fromleaks in plenum ducts)—put plumber’s putty orsimilar material inside the conduit to block airflow.TTAO2AO1AI1Mounted on an exterior wall.

If the thermostat is locked on the backplate, turnthe two hex screws (in the two outermost holes)in the backplate CLOCKWISE until they (just)clear the cover. Swing the thermostat up andaway from the backplate to remove it.NOTE: For detailed applications, cross-references,accessories, and other information, see theCTE-5202 Applications Guide.Rough-in PreparationFor optimum temperature sensor performance, thethermostat must be mounted on an interior walland away from heat sources, sunlight, windows,air vents, and air circulation obstructions (e.g.,curtains, furniture).CAUTIONTo prevent damage to the board, do not inserta screwdriver into any holes other than the twooutermost holes. To prevent mounting screw headsfrom touching the circuit board in the thermostat, useonly the mounting screws supplied by KMC Controls.Using other screws may damage the thermostat. Donot turn screws in farther than necessary to removethe cover.If replacing an existing thermostat, label wires asneeded for reference when removing the existingthermostat.Complete rough-in wiring at each location prior tothermostat installation. Cable insulation must meetlocal building codes.CTE-5202 Electronic Room Thermostat with LCD Display2. Route the cable through the backplate.1Installation and Operation Guide

External Input (AI1)Additional ResourcesHot/Cold Air ChangeoverThe latest support files are always available on theKMC Controls web site (www.kmccontrols.com).For hot/cold air changeover on Sequence 1 or 2,connect a changeover (temperature) sensor to theAI1 input. The sensor should be a Type III thermistor(10K ohm @ 77 F), such as a KMC STE-140x ductsensor or STE-1454/1455 strap-on sensor. (An internal 10K ohm pullup resistor is provided on AI1.)NOTE: For specifications and other information,see the CTE-5202 Data Sheet.Leave sensor off for continuous cold air mode.Unoccupied/Standby SetbackContact closure across AI1 and Common initiates thestandby setback offset sequence, which causes thecooling setpoint to increase and the heating setpoint(in Sequence 2 or 3) to decrease by the amount of thesetback offset. (This setback does not apply duringthe morning warm-up of Sequences 1 and 2.)NOTE: For detailed applications, cross-references,troubleshooting, accessories, andother information, see the CTE-5202Applications Guide.MaintenanceRemove dust as necessary from holes in top andbottom.
