Uponor hydronic heating setpoint controller
October 27, 2014
Updated with a new look and feel, Uponor’s single-stage setpoint controller with floor sensor accurately controls the room and/or floor temperature for a hydronic heating zone, using Pulse Width Modulation technology.

Simple up and down buttons and a display with large type make this thermostat easy to read and use. An optional floor sensor is included to measure floor temperature in order to protect the floor from overheating and to enhance comfort.
