Description of product

Properties of R3V-421:

The controller enables according connected temperature sensors (max. 8) controlling three-way / four-way valves, pumps, switching boiler and to regulation the temperature according to the selected  function.
It can be used for example in the following systems
- single and multiple circuit systems (radiators, floor heating)
- for discharging of storage tank
- for solid fuel boilers (regulation of return water temperature)
- where, does not regulate the heat according to outdoor temperature (equithermal regulation=weather-compensated reg.)
