Tekmar Controls 084 Sensor
The Tekmar Controls 084 Sensor is a professional-grade 10,000 ohm NTC thermistor engineered for discrete, high-accuracy temperature monitoring in hydronic and HVAC systems. Designed with a flush mount indoor sensor profile, this unit provides veteran installers with an unobtrusive alternative to bulky wall-mounted thermostats. The corrosion-resistant white PC-ABS plastic disk allows for remote temperature sensing while remaining aesthetically neutral. Contractors can easily integrate the 084 into a Tekmar thermostat system by roughing in 18 AWG two-conductor wire up to 500 feet before drywall installation. Its wide operating range of -60 to 140°F (-51 to 60°C) ensures stable resistance feedback across diverse indoor environments, including high-humidity areas up to 90% non-condensing. Because the sensor housing is mud-compatible, it can be seamlessly painted or wallpapered over to match any interior finish. Professional technicians prefer this HVAC temperature sensor for its reliable 10k Type 2 thermistor curve (Beta = 3892), which guarantees precise PID algorithm performance and prevents short-cycling or temperature overshooting.
Key Benefits- Discreet Architectural Integration: The flush-mount disk acts as a hidden indoor sensor that can be mudded, sanded, and painted over for a completely invisible installation.
- Universal Tekmar Compatibility: Designed specifically for remote temperature sensing when connected to Tekmar thermostats that support auxiliary sensor inputs.
- Wide Environmental Tolerance: Rated for specialized applications with a sensing range from -60°F to 140°F, making it suitable for standard rooms or temperature-controlled zones.
- Robust Signal Reliability: Supports long-distance wire runs up to 500 feet using standard 18 AWG wire, provided sources of electromagnetic noise are avoided.
- Corrosion-Resistant Build: Constructed from durable white PC-ABS to withstand moisture and chemical exposure from drywall mud and paint.
Can the Tekmar 084 be used for outdoor sensing?
No, this model is strictly rated for indoor use only. For exterior ambient temperature monitoring, use a dedicated outdoor sensor housing like the Tekmar 070.
What type of wire should be used for the 500-foot run?
Standard 18 AWG two-conductor wire is sufficient for most installations. However, if the path runs parallel to high-voltage lines or telephone cables, use shielded cable or twisted pair to prevent signal interference.
How do I troubleshoot an inaccurate temperature reading?
First, check for drafts behind the sensor; the wiring hole in the drywall must be sealed to prevent wall cavity air from affecting the 10k thermistor. Then, disconnect the wires and test with an ohmmeter to compare the resistance against the standard Tekmar 10k temperature-resistance chart.
