Abstract

A control apparatus for an electric bed heating arrangement (24) includes a 24 hour timer circuit (36) which, after the apparatus has been energised from an electrical supply: (i) disables energisation of the bed heating arrangement (24) until a manual operation of setting the timer circuit (operation of a reset/override switch) has been performed; and (ii) responds to the manual setting operation to commence a 24 hour cycle according to which energisation of the bed heating arrangement is enabled each day, at a time determined by the time of day at which the manual setting operation was performed, and continues thereafter to be enabled for a predetermined part only (e.g. 12 hours) of the 24 hour cycle. When, for example after first purchase or at the end of the warm season, use of the bed heating arrangement is to be commenced, the user need only connect the control apparatus to an electrical supply and then perform the manual setting operation at an appropriate time of day. Thereafter, provided the apparatus is left connected to the supply, heating of the bed will be enabled each day at the same time as that determined by the time at which the setting operation was performed and will be disabled each day at the same time, namely at the end of the predetermined part of the 24 hour cycle.
