The Viega 16016 ProRadiant Indoor Sensor is a temperature sensing device designed for use in radiant heating and hydronic systems. It monitors indoor ambient air temperature and sends that data to a compatible control system, allowing the system to regulate heat output accurately. HVAC technicians and radiant heating installers rely on indoor sensors like this one to keep comfort levels consistent and to prevent systems from overheating or underperforming. The Viega 16016 operates across a wide temperature range of -60 to 140 degrees Fahrenheit, making it suitable for a broad range of indoor environments, from cold utility spaces to warm living areas. This range gives the sensor versatility across residential and light commercial radiant floor heating installations. In a radiant heating system, the indoor sensor works alongside outdoor sensors and thermostats to create a complete picture of the thermal environment. The control unit uses this information to adjust water temperature in the heating loops, a process known as supply water reset. This improves system efficiency and reduces energy consumption. Proper sensor placement is important. The sensor should be mounted on an interior wall away from direct sunlight, drafts, and heat sources that could skew the reading. When installed correctly, it provides reliable and repeatable temperature data over the life of the system. The Viega 16016 is an imported component that integrates with the ProRadiant line of controls and accessories. Hydronic system installers, mechanical contractors, and HVAC service technicians working with Viega ProRadiant equipment will find this sensor a straightforward replacement or new installation part. It supports accurate zone control and long-term system performance in radiant heating applications.
The Viega 16016 ProRadiant Indoor Sensor provides reliable ambient temperature measurement across a wide range, helping radiant heating systems maintain consistent comfort and efficient operation.
