R3V Three/Four-Way Valve Controller

Product detailed description

Features of the R3V controller:

NEW VERSION 11.03 (ON SALE FROM 1.11.2014 )

  IMPROVED VERSION IN TERMS OF USER SETTINGS AND PLEASE NOTE  A TRIAC IS USED AS THE SWITCHING ELEMENT (only for resistive and inductive load - for devices without a starting capacitor)! A relay (5A) is used for the pump.

Depending on the selected control mode, it is possible to adapt the control to the given system by setting constants.

It finds application, for example, in the following systems
- single and multi-circuit systems (radiators, underfloor heating)
- for discharging the accumulation tank
- for solid fuel boilers (control with regard to the return temperature)
- where the heat source does not allow control according to outdoor temperature (equithermal control).

Types of control:

• Control according to room temperature (PI control)
• Equithermal control with room temperature compensation
• Equithermal control according to outdoor temperature
• Control according to temperature behind the valve
• Control according to return temperature

Advantages of R3V:

• 7 weekly programs with 6 temperature changes per day
• two-line alphanumeric display with clear navigation and function description
• AUTO/ AUTO OFF/ MANU/ MANU OFF mode selection
• anti-freeze protection
• automatic protection against limescale
• short-term temperature change
• information about temperatures on the sensors, calculated temperature at the valve, and an approximate value of the valve position in %
• power supply 5 V/DC, 500 mA
• possibility of connecting up to 4 temperature sensors ( 2x CT01-10k, 1x CT02-10k are included in the package )
• possibility of connecting a thermostat for remote control in equithermal control, according to valve temperature and return temperature
• max. load on outputs (Imax) is 0.5 A.
