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

Benefits of the R3V-422:

  • 7 weekly programs with 6 temperature changes per day
  • language selection (CZ/EN)
  • AUTO/ MANU/OFF mode selection
  • monitoring the maximum boiler temperature
  • maximum temperature monitoring for storage tank
  • adaptation of valves after activating the regulators
  • operation back-up in case of power cut for more than 4 hours
  • selection of maximum valve step
  • anti-freeze protection
  • automatic protection against limescale
  • short-term temperature change
  • Information on temperatures on the sensors, calculated temperature on the valve and orientation value of the valve position in % for each connected circuit
  • of power supply 5 V/DC, 500 m A (the AD05-DIN source is not part of the package)
  • optional connection up to 8 temperature sensors (part of the package are KO, VT, M1, V1, Z1 sensors and others can be additionally purchased at www.elbock.cz)
  • optional connection of the thermostat for remote control
  • max. load of outputs (I max) is 5 A
