Installation Operation Maintenance

ControlsClogged filter detectorThis device is mounted in the filtersection. The detector measures thedifference in pressure before andafter the filter section. The cloggedfilter information is sent to theTPH03 thermostat, to the TRACKERor to the BMS. The setting range is40 to 300 Pa.Figure 23 - Clogged filter detectorlocation1. Clogged filter detectorSmoke detectorThis device is used to detect smokein the air stream. It includes afactory mounted detectorconnected to a central panel, bothfitted in the fan section.When smoke is detected, it shutsoff the unit. A dry contact isavailable on the control panel for aremote default.1High temperature safetythermostatThis additional safety device is amanual reset thermostat for gasfired units (YKD/YKH), requiredmainly by the French ERPregulation.It is located in the gas burnersection. It stops the gas burner andthe supply air fan when the supplyair temperature rises to 120°C.Supply air sensingLocated in the supply fan section,this temperature sensor reports thesupply air temperature to thecontroller. With the TCI-3 option, itcan be used to report thetemperature to the TRANEsupervisor.Remote fault relayThis is a factory-mounted relay usedto remote alarm signals (drycontact) to a local BMS or a localcontrol panel. With this relay, thecompressor, heating, fan/ andpower supply alarm output signalsfrom the controller are reported to asingle dry contact.Figure 24 - Smoke detectorCAUTION! : The smoke detectorsensor must be cleaned upperiodically to avoid repeated cutouts.For safety reasons, the manualreset on the smoke detector mustbe avoid. It is recommended toswitch off/on the unit with thedisconnect switch.36RT-SVX16C-E4
