Electronic card of a boiler / boiler camper now obsolete and nowhere to be found, with a problem: boiler in block after 10 seconds of operation. Fortunately with careful research I met the guys from Beta Technologies. Sent everything, very careful and precise with email for each operation carried out, they sent me back everything in perfect working order. Thank you thank you thank you and thanks again. Good, serious, precise and cheap !!!!
