Two-circuit valve regulator

Description of product

Properties of the R3V-422 regulator:

The regulator allows according to the connected sensors (max. 8) control of three-way/four-way valves, pumps, switch the boiler and control the temperature according to the selected function.
It can be used for example in the following systems
- one and two circuit systems (radiators, underfloor heating)
- for charging and discharging storage tank
- for a solid fuel boiler (control with regard to the return valve)
- where, the source of heat does not allow control according to the outdoor temperature
  (equithermal control).

Types of control:

• Control according to the temperature in the room with a temperature sensor (PI control)
• Control according to the temperature behind the valve with regard to the room thermostat
• Equithermal control with evening up according to the temperature in the room with the temperature sensor
• Equithermal control according to the outdoor temperature with regard to the room thermostat
• Control according to the temperature of the return valve with the temperature sensor
• Control according to the temperature of the return valve with regard to the room thermostat
• Control according to the temperature of the return valve, charging of the storage tank (AKU) with regard to the temperature of the boiler (flue sensor) and room temperature with optional external additional heating (ExD)
• Control according to the temperature of the return valve and charging of the storage tank (AKU) with hysteresis with optional external additional heating (ExD)
• Service mode
• Summer mode
