ABSTRACT:
A central heating control system includes a control panel housing a timer. The timer has three programme sequences for controlling three groups of radiators each group being independently controlled. The control panel also includes switch units which are selectively operable to isolate each radiator. The switch units are triggered by infrared signals transmitted by a portable control unit. The signals may be received directly by the panel or indirectly through spaced windows coupled to the control panel by an optical fibre network. The system provides an exceptionally convenient method of modifying a programmed heating system.
