TEMPERATUREKELE ROOM TEMPERATURE SENSOR, THERMISTOR, AND RTD<strong>KTR</strong> * SERIESDESCRIPTIONThe <strong>KTR</strong> * Room Temperature Sensor is a cost-effectiveroom temperature sensor with an accuracy of±0.5°F (0.28°C). The thermistor is made of a very stable,pre-aged material that offers the reliability needed incontrol systems. The platinum RTD comes in 100Ω and1000Ω and is compatible with most HVAC systems. Allsensors come with a three-year warranty.FEATURES• Economical• Attractive new design• Three-year warranty• ±0.5°F (0.28°C) accuracy• Durable housing• White color• Thermistor or RTD• Locking cover screwsDIMENSIONS<strong>KTR</strong>*<strong>KTR</strong>*-A10K-J1-LED-MDOPTIONS• Setpoint slide adjust• Momentary override switch• RJ11 communication jack• NIST certificate• 24V LED lamp• OEM models available• Custom logosAPPLICATIONThe <strong>KTR</strong> * Series is designed to be wall mountedindoors where appearance and accuracy are important.The sensor may be mounted directly to the drywall oron standard electrical boxes. It comes in all the mostcommon thermistors or RTDs.
