Abstract

An environmental control arrangement includes an electronic time switch controller with a memory for storing information relating to switching times in each of a plurality of zones to be controlled. Information is fed into identifiable locations in the store, and means are provided for comparing the stored information with data representative of the time of day to provide an output whenever the time of day corresponds to one of the stored switching times. The invention has particular application in a central heating system. <IMAGE>
