NCM300 panelThermalBreakerThe NCM300 has a 2.5amp thermal circuitbreaker in place of a fuse that protects theNCM300 from shorted circuits in thethermostat and damper field wiring. It willnot protect against shorts in the HVACsystem wiring. DO NOT exceed a 60vatransformer to power the panel.NOTE: When the circuit breaker is tripped it willget hot and all of the panel LED’s will stopfunctioning. To reset the breaker, locate theshort by removing all wires connected to thepanel, one at a time. When the shorted wire isremoved the panel will resume normaloperation. Now you must repair or replace theshorted wire before you re-connect it.OperatingConditionsTEMPERATURE: -20 to 160 F (-29 to71 C)HUMIDITY: 0% - 95% RH Non-Condensing.Indoor FanControlAny zone can activate the indoor fanand only the dampers in zones callingfor continuous fan operation will open.Continuous fan operation will onlyoccur when there are no active orpending heat or cool demands.EWC Controls Inc. 385 Highway 33 Englishtown, NJ 07726 800-446-3110 FAX 732-446-5362P/N 090375A0226R23U6A total of 9 function specific, coloredLED’s indicate the system status andmode of operation.LEDs labeled Zone 1 thru Zone 3indicate which dampers are energizedto open.R19C7R38R37SYSTEMW2/EW1/BOYGRHRCCR69 ZONE 3T'STATR13U3HP SYSTEM GASHC TSTATS HPOFF PURGE ASST ON90 PURGE 120 S0 FAN DLY 45 SO RV BOFF SAS ONGAS FAN HYDROR351R70RESETC5D6R6U1C92R9C4R28R17R16K2 R21D4 R20R22F1U2D2C8R27R317K3D5 R66Z1C2C1SUPPLYAIRR10 SENSORR5170HIGH TEMPLIMITNCM-300RCompatibleHVAC Systems110C3 D1 R4 R8150160R26ZONE 1MOTOR14049 120K1D3ZONE 2MOTOR1304637R7M6M4M2M1434035Copyright EWC/ACI 2006ALL rights reservedControls two or three air zones with24vac Power Open/Close or SpringAssisted motorized dampers.Zone CapacityZONE 3MOTORNCM300 Ver 2.3The New NCM300 panel provides intelligent control of HeatPump or Conventional forced air zoning systems at amaximum of three zones using motorized dampers andpractically any off-the-shelf thermostat.

WIRING INSTRUCTIONSWARNING: THESE PANELS ARE DESIGNED FOR USE WITH 24VAC. DO NOT USE OTHER VOLTAGES! USE CAUTION TOAVOID ELECTRIC SHOCK OR EQUIPMENT DAMAGE. ALL WORK SHOULD BE PERFORMED TO LOCAL AND NATIONALCODES AND ORDINANCES. USE 18 AWG SOLID COPPER, COLOR-CODED, MULTI-CONDUCTOR THERMOSTAT CABLE.The NCM300 zone control panel requires standard 1 stage heat/cool thermostats in all zones, regardlessof the application. 2nd stage heat output is controlled by an adjustable timer on the panel. If you prefer,the NCM300 will also work with any off the shelf 2 stage Heat Pump Thermostat. 2nd stage heat will thenbe thermostatically controlled.

This allows the user to override the W2 Timer and energize the auxiliary heat via thermostatic demand! You may still use regular Heat/Cool typethermostats with a Heat Pump system and use the W2 Timer to energize the auxiliary heat. Doing so may save moreenergy. This new design simplifies the thermostat selection process and allows the installer to easily adapt theNCM300 to most residential applications.EWC Controls Inc. 385 Highway 33 Englishtown, NJ 07726 800-446-3110 FAX 732-635-8646E-Mail- info@ewccontrols.com3

SERVICE GUIDESome HelpfulGuidelinesAll voltage measurements on theNCM300 panel should be made with theground lead of your meter on terminal “C”of the 24VAC input terminals.All voltage measurements at the HVACSystem Terminal Block (W1/B, O, Y,W2/E & G) should be made with themeter’s ground lead on the terminal “C”at the HVAC system block.Using the LEDIndicatorsCheck 24VACPowerMeasure 24VAC at all damper M1 andM2 terminals and all T-stat R and Cterminals. See Table 1 if any of thesevoltages are incorrect.HVAC SystemNot RespondingProperlyIf the HVAC LED indicators areresponding properly, but the systemappears to be malfunctioning, checkthat the HVAC system is wired correctlyand that the DIP switches have beenproperly set.The green STATUS LED should blink at1second on / 1 second off, to indicate themicroprocessor is operating properly and24v power is present.The red SUPPLY AIR LIMIT LED willilluminate if the panel senses a dischargetemperature in excess of the high or lowlimit set points. The LED will blink rapidlyif the sensor is open,shorted ordisconnected. The panel will functionnormally, but no supply air temperaturecontrol will occur until the open or shortedsensor is replaced.The green Zone Damper LED’s willilluminate to indicate which dampersshould be open.If the HVAC LEDs are not respondingproperly, check the calls on each zonethermostat. If the calls indicate that theHVAC system should be activated andis not, press the RESET switch tocancel the timers. Also check that theDIP switches have been properly set. Ifthe problem persists, see Table 3 fortrouble shooting help.Table 1. Detecting 24VAC ShortsDetecting24vac ShortsAll LED’s will be off and the panelwill appear to be dead! you willmeasure 24VAC at the transformerterminals R & C, but not at any damperM1&M2 terminals, or any zonethermostat R & C terminals.CAUTION: The thermal breaker will behot to the touch.Isolating24vac ShortsRemove the power to the panel andallow the thermal poly fuse to cooldown.The red W1/B LED indicates that thepanel is in the 1st stage heating mode or,the “B” type reversing valve output isactive.The red W2/E LED indicates 2nd stageheat or Emergency heat has beenenergized.The yellow COMPRESSORLEDindicates the compressor is energized.The green FAN LED indicates the indoorfan is energized.Dampers NotRespondingProperlyIf the Zone LED indicators are illuminatedbut the dampers appear to bemalfunctioning, check the damper fieldwiring.If the ZONE LED’s are not respondingproperly, check the calls on each zonethermostat. If the calls indicate a dampershould be energized and is not, press theRESET button to cancel the timers. If theproblem persists, see Table 2 for servicehelp.6Remove the wire at each zonethermostat R terminal and test if theshort still persists by restoring power tothe zone panel and testing asdescribed above. If the short disappears, check the zone thermostatwiring and the thermostat itself. Thisapplies if the thermostat requires the 24volt (C)common, or the R wire could beshorted to the building ground.If the short still persists disconnect allthe wires at each damper terminal (M1,M2, M4 & M6). Restore power and testas described above. If the short clears,check the damper wiring and thedampers for shorts with a continuitytester. If the short still persists, call thetechnical support hot-line.EWC Controls Inc. 385 Highway 33 Englishtown, NJ 07726 800-446-3110 FAX 732-635-8646E-Mail- info@ewccontrols.com
