Description
The Watts 0792038 Wireless TempMod Outdoor Reset Control is an intelligent hydronic heating solution designed to maximize system efficiency and occupant comfort. By continuously monitoring outdoor temperatures and wirelessly communicating with the heating system, this control automatically modulates the supply water temperature to match real-time heating demand — eliminating energy waste caused by fixed high-temperature operation.
How It Works
Outdoor reset control is a proven strategy in hydronic heating: as outdoor temperatures rise, the system lowers the boiler or heat source supply water temperature accordingly. The Watts TempMod does this wirelessly, simplifying installation by eliminating the need to run sensor wiring from the outdoor sensor to the control panel.
Key Features
- Wireless outdoor temperature sensing for flexible, low-labor installation
- Automatic supply water temperature modulation based on outdoor conditions
- Designed for hydronic heating systems including boilers and radiant applications
- Reduces energy consumption by preventing unnecessary high-temperature operation
- Improves system longevity by minimizing thermal stress on boiler components
- Watts quality engineering for reliable, long-term performance
Benefits of Outdoor Reset
- Improved comfort through consistent, demand-matched heating
- Lower fuel costs by optimizing supply water temperature year-round
- Reduced boiler cycling, extending equipment life
- Ideal for radiant floor, baseboard, and panel radiator systems
Application
The Watts 0792038 is well-suited for residential and light commercial hydronic heating installations where running outdoor sensor wiring is impractical or cost-prohibitive. Its wireless design makes retrofitting into existing systems straightforward, while new installations benefit from reduced labor and material costs.
