WATERWARE UF182 Underfloor Mixing Panel
Function
The set point regulating unit performs the function of keeping the flow temperature constant, at the set value in a low temperature underfloor heating system. In this particular series, the temperature is regulated by a specific hydraulic unit equipped with a thermostatic three-way valve with a built-in sensor.
Operating Description
The regulator element inside the thermostatic three-way valve consists of a temperature sensor fully immersed in the mixed water outlet chamber. By expanding and contracting, it continuously ensures a correct proportioning of hot water, coming from the boiler, and water returning from the panel circuit. The water intake is regulated by a shaped obturator that slides inside a special cylinder placed between the hot water flow and the water returning from the circuit. Even if the thermal load of the secondary circuit or the inlet temperature from the boiler change, the mixing valve automatically adjusts the flow rates until it obtains the set temperature.

Temperature Adjustment and Locking
The control knob is used to adjust temperature in a full turn (360°) between minimum and maximum. It also has tamper protection for locking the temperature at the set value. To set, turn the knob onto the required number, unscrew the upper screw, remove the knob and put it back on so that the internal reference couples with the protrusion on the knob carrier ring nut.
