DIN rail heating controller FM 443

for solar water heaters

Buderus 4000 series boiler controls can be fitted with the intelligent FM 443 solar module to allow optimum solar and heating functionality. With this fully integrated energy management system the boiler recognises the solar output and delays the boiler firing for as long as possible by continuously monitoring charges in head demand. This not only reduces the wear and tear on the heating system, by reducing burner start ups & by up to 24%, but can also provide an additional 10% of energy savings. Combining a Buderus heating system with Buderus solar panels can provide significant efficiency and performance benefits and is the best way to ensure that your panels work in harmony, rather than separately.
