Equithermal Controller for Three/Four-Way Valves R3V-A3

Product detailed description

Features of the R3V-A3 controller:

It is used for continuous regulation of the mixing valve actuator depending on the
outdoor temperature (CT1 sensor) and return temperature (CT4 sensor). It is important to select
the optimal equithermal curve and, if necessary, manually shift it. If the boiler outlet
temperature (CT3) is higher than 60 °C, the circulation pump switches on.
The temperature sensor (CT4) measures the return temperature and controls the mixing valve so
that a return temperature of at least 60 °C is achieved. Once this temperature is reached,
the device switches to controlling the water temperature after the valve (CT2) and ensures the optimal
water temperature based on the selected equithermal curve.

Advantages of R3V-A3:

• easy setup
• possibility to connect a temperature contact and thermostat for remote control
• reliable operation
• low consumption
• automatic protection against limescale

Practical use:

- regulation of the heating system medium temperature according to the outdoor temperature, for family houses
