<strong>Maintenance</strong>Service FailureMeasure the voltage betweenterminals J6-10 & J6-6.Clogged Filter = Approximately32 VDC.Normal = Less than 1 VDC,approximately 0.75 VDCFan Failure = voltage alternatesbetween 32 VDC & 0.75 VDC.To use LED's for quick statusinformation at the unit, purchase aZSM and connect wires withalligator clamps to terminals 6through 10.Connect each respective terminalwire (6 through 10) from the ZoneSensor to the unit J6 terminals 6through 10.Note: If the system is equippedwith a programmable zone sensorTHS03, the LED indicators will notfunction while the ZSM isconnected.Resetting Cooling and IgnitionLockoutsCooling Failures and IgnitionLockouts are reset in an identicalmanner. Method 1 explainsresetting the system from the space,Method 2 explains resetting thesystem at the unit.Note: Before resetting CoolingFailures and Ignition Lockouts,check the Failure Status Diagnosticsby the methods previouslyexplained.Diagnostics will be lost when thepower to the unit is disconnected.Method 1To reset the system from the zone,turn the "Mode" selection switch atthe zone sensor to the "Off"position.After approximately 30 seconds,turn the "Mode" selection switch tothe desired mode, i.e. Heat, Cool orAuto.Method 2To reset the system at the unit,cycle the unit power by turning thedisconnect switch "Off" and then"On".Lockouts can be cleared through thebuilding management system. Referto the building management systeminstructions for more information.Zone Temperature Sensor (ZTS)Service IndicatorThe ZSM SERVICE LED is a genericindicator that will signal the closingof a Normally Open switch at anytime, providing the Indoor Motor(IDM) is operating. This indicator isusually used to indicate a cloggedfilter, or an air side fan failure.The RTRM will ignore the closing ofthis Normally Open switch for 2 (±1)minutes. This helps preventnuisance SERVICE LED indications.The exception is the LED will flash40 seconds after the fan is turned"On" if the Fan Proving Switch is notmade.Clogged Filter SwitchThis LED will remain lit the entiretime that the Normally Open switchis closed. The LED will be turned offimmediately after resetting theswitch (to the Normally Openposition), or any time that the IDMis turned "Off".If the switch remains closed, andthe IDM is turned "On", the SERVICELED will be turned "On" again afterthe 2 (±1) minute ignore delay.This LED being turned "On", willhave no other affect on unitoperation. It is an indicator only.Fan Failure SwitchWhen the "Fan Failure" switch iswired to the RTOM, the LED willremain flashing the entire time thefan proving switch is closed,indicating a fan failure, and it willshut the unit operations down.64RT-SVX20B-E4
<strong>Maintenance</strong>Zone Temperature Sensor (ZTS) TestNote:These procedures are not forprogrammable or digital modelsand are conducted with the ZoneSensorModule electrically removed fromthe system.Test 1Zone Temperature Thermistor(ZTEMP)This component is tested bymeasuring the resistance betweenterminals 1 and 2 on the ZoneTemperature Sensor.Table 55 - Thermistor Resistance /Temperature ChartTemperature/resistance coefficient isnegative.Temperature Resistance(°C)(kOhms)-21 103-15 74.65-9 54.66-7 46.94-4 40.4-1 34.852 30.184 26.227 22.8510 19.9613 17.4716 15.3318 13.4921 11.8924 10.527 9.29729 8.24732 7.3335 6.52838 5.824RT-SVX20B-E465
