The Honeywell TL8100 Hydronic Thermostat is an entry-level, 7-day programmable thermostat. It offers basic temperature control options only (no humidity, filtration, etc.), but it provides +/- 1-degree Fahrenheit precision to help users save up to 10% on their heating bills. Additional features include an at-a-glance heating indicator, a low battery indicator, and an early start function that ensures the programmed temperature is reach by a programmed time. Signature though is the unit’s flexibility, as it also works with gas, oil and some electric heating or hot air systems. Plus the unit automatically actives its hydronic components once every day to prevent system seizures.
