Hi- I recently ran across this, a HBX WAV-100 Universal Wireless Temperature Sensor and thought it might be interesting to others, especially those using (or thinking about using ) a Tekmar 279 steam control. While it is designed as an out door sensor, it can also be used as an inside sensor. Since i have a steam system, this sensor was the item that interested me. Those of you who have HW systems might want to take a look at their other controls.
It's a bit pricey for what it does, on the other hand it looks like a good fit anywhere you'd need a thermistor-based non-contact temperature sensor. I'm interested in trying one out on my home-grown controls as an indoor temperature sensor I can move around.
I asked HBX how the unit would behave in the case of a bad sensor or dead battery; they told me the base unit would retry for some period of time then default to a constant 0 degF reading.
