Abstract

An electrical control unit for central heating systems includes a backplate (10) to which electrical connections may be made at a plurality of positions. A housing (11), containing control circuits and contacts (24) for making connection between the circuits and the backplate connections, is removably attached to the backplate. Access to the electrical connections on the backplate for testing purposes may be achieved with the housing attached and electrically connected to the backplate, but a cover (26) on the backplate may be positioned to prevent such access during normal operation of the unit. The unit also includes two control switches of which one is operable independently of the other or of which both are independently operable upon release of an interlock. <IMAGE>
