CONTROL MEANS FOR HOT WATER SYSTEMS

摘要

Control means for a hot water system including a microprocessor having a programmable memory (15) and a logic circuit (10) which receives data from the system and responds in a manner as directed by the memory. The response may involve a change in the operating parameters of the system or generation of a signal indicating the presence of a fault in the system. The control means is operable to regulate the heating cycle of the system so that it takes place only when the temperature conditions of the system require and subject to other factors being satisfactory such as the load on the mains supply used to energize the system.
