Definitions

  • the present invention relates to a timing control unit and in particular to a timing control unit for a central heating or hot water system.
  • the invention further relates to a switch suitable for use in such a control unit and to a central heating or hot water system incorporating such a control unit.
  • Domestic central heating/hot water systems are typically provided with a timing control unit to allow user to set the heating and or hot water to be switched on or off automatically at desired times throughout the day.
  • a number of different control units for such systems are available.
  • the dial rotates fully once every twenty four hour period and is marked round its outer edge with the hours of the day.
  • a reference mark is provided adjacent to the dial indicating the current time.
  • the control unit is typically provided with additional switches allowing user to set whether the tappets control the heating, the hot water or both. These additional switches particularly also allow the user to override the timed element of the timing control unit if desired.
  • Timing control units of this type are relatively cheap and robust. Such timing control units are very simple and intuitive to use, however they provide very limited flexibility for a user in how they wish to control their heating or hot water system.
  • Timing control unit is a digital timing control unit.
  • Such control units are particularly provided with a digital clock and various user actuable push buttons, which allow a user to program to the nearest minute the times at which the heating and hot water systems will be switched on and off.
  • These units typically allow more accurate and more flexible programming than the simpler units described above.
  • These units are considerably less simple and intuitive for a user to program. As a result users may not utilise the full range of functions of the control unit or may even find it difficult to use the basic functions of the control unit without consulting an instruction manual.
  • a timing control unit of the type operable to activate or deactivate one or more external devices at predetermined times comprising: a display means in the form of a plurality of illuminable segments, each segment corresponding to a particular time interval and each segment being either illuminated or not illuminated to indicate whether the external device or devices are to be activated or deactivated during the corresponding time interval; and means for varying the activation times of the external devices, the means comprising a rotatable element, movement of the element resulting in corresponding variations in the activation times of the external devices and the illumination of the illuminable segments.
  • This provides a control unit that may be easily and intuitively operated by a user.
  • illumination of a segment corresponds to activation of the external device or devices during the time interval represented by that segment.
  • the rotatable element comprises a rotatable control element.
  • rotation of the rotatable control element varies the periods of time when the external device or devices are activated and correspondingly varies the illumination of the segments.
  • the rotatable control element is adapted such that a particular segment may be selected by pressing the rotatable control element.
  • the illuminable segments are arranged in a ring around the rotatable control element
  • the segments preferably correspond to equal time intervals throughout a control period.
  • the control period is preferably a twenty four hour period.
  • the segments may correspond to any desired time interval within the control period including, but not limited to, any one of: ten minutes, fifteen minutes, twenty minutes, thirty minutes and one hour.
  • the segment corresponding to the time interval in which the present time falls may be illuminated intermittently.
  • the control unit may be adapted to activate the device or devices during one or more activation periods during a control period.
  • the activation periods may be a single time interval; an extended time interval comprising a plurality of consecutive time intervals; a plurality of extended time intervals each comprising a plurality of consecutive time intervals; or any other such times or time intervals as desired.
  • the possible durations of such activation periods and the possible separation of individual activation periods is limited by the duration of the time interval to which each segment corresponds, for instance, activation periods may only have durations and separations that are multiples of fifteen minutes if each segment corresponds to a fifteen minute time interval.
  • the control unit may be adapted to provide for control of a plurality of different devices at different activation periods.
  • actuable means being provided for selecting a particular output cliannel.
  • the actuable means may be one or more push switches.
  • the ring of segments is illuminated to indicate the activation periods during which the device or devices controlled by the selected channel are activated, and when a second channel is selected, the ring of segments is illuminated to indicate the activation periods during which the device or devices controlled by the second selected channel are activated.
  • the activation periods for a time period are set by the method of: selecting an output channel using the actuable means; rotating the rotatable control element to the desired start of the activation period; pressing the rotatable control element to select the desired start of the activation period; rotating the rotatable control element to the desired end of the activation period; and pressing the rotatable control element to select the end of the desired activation period.
  • further desired time intervals may be set by repeating the above process.
  • the actuable means may also be used to select whether one or more activation periods are desired.
  • the time interval segment currently selected by the rotatable control element may be indicted by being illuminated intermittently. Once a start time is selected, as the rotatable control element is rotated to the desired end time, selected segments are progressively illuminated.
  • the control unit may be adapted to allow the activation periods of an output channel to vary during successive control periods.
  • the ring of segments may correspond to a day and it may be desired to provide different activation periods on different days of the week. This may be indicated by providing a separate set of illuminable segments corresponding to the days of the week.
  • the actuable means may be used to select each day of the week individually and then the above method may be used to select the desired activation periods on each particular day.
  • An additional information display unit may be provided on the control unit.
  • the additional information display unit may be operable to display any suitable type of information relating to the operation or settings of the control unit.
  • a central heating system or a hot water system or a combined central heating and hot water system controlled by a timing control unit of the type hereinbefore described.

  • the push switch is preferably provided within the housing. The portion of the knob which is not within the housing may be pressed back into the housing to operate the push switch.
  • the control unit comprises a rotatable knob 110 disposed within a ring of illuminable segments 120. Each segment in the ring 120 corresponds to a fifteen minute time interval during a day.
  • a ring of numbers 130 is provided adjacent to the ring of segments 120 to indicate the hours of the day that the segments 120 correspond to.
  • part of ring 130 is shaded darkly 131 to indicate nightime hours whilst the remaining part 132 is shaded brightly to indicate daytime hours.
  • two sets of segments 121 are illuminated and two sets of segments 122 are not illuminated.
  • the illuminated segments correspond to the times of the day when the heating/hot water system is activated, referred to herein as activation periods. At any one time one segment will be illuminated intermittently to indicate the present time, typically at a frequency of say, 1Hz. Conveniently, the segments may be illuminated by a ring of dedicated LEDs.
  • a number of actuable push switches 141-144 are provided.
  • the actuable switches 141-144 are used to change the operable mode of the control unit 100.
  • switch 141 sets the control unit to activate the heating/hot water system for two time periods during the day.
  • Switch 142 sets the control unit to activate the heating/hot water system for one time period during the day.
  • Switch 143 sets the control unit to activate the heating/hot water system continuously.
  • Switch 144 sets the control unit to deactivate the heating/hot water system continuously.
  • An indicator light 145 is provided, the light 145 being illuminated to indicate that the heating/hot water system is activated.
  • the activation periods are set by first selecting either switch 141 or 142, then the knob 110 is pressed. This causes the segment corresponding to the start of the activation period to flash intermittently at an increased rate, say, 2Hz. The knob 110 is then rotated, the flashing segment moving as the knob rotates, until the flashing segment is moved to the desired start time for the activation period. As the flashing segment moves, any segments that were not within the activation period but are now within the activation period are illuminated and any segments that were within the activation period and are not now within the activation period are not illuminated. The knob 110 is then pressed to set this as the start time for the activation period. Once the knob 110 has been pressed, the segment corresponding to the end time of the activation period starts to flash at the increased rate.
  • the knob 110 can then be rotated to the desired end time of the activation period. As above, any segments that were not within the activation period but are now within the activation period are illuminated and any segments that were within the activation period and are not now within the activation period are not illuminated.
  • the knob 110 is then pressed to set the end of the activation period. As a result, the segment corresponding to the start of the second activation period starts to flash at the increased rate.
  • the above process is then repeated to set the second activation period. If it is desired not to set a particular activation period, the start time can be set to be the same as the end time. The period will then only be displayed when in setting mode.
  • the control unit 100 is also provided with additional actuable control switches 151, 152 and 153.
  • Switch 151 advances the control unit 100 to the next activation period. When it is actuated, all the segments from the present time to the start of the next activation period are illuminated and the heating/hot water system is activated. As time elapses, the segments are progressively switched off until the start of the set activation period is reached. As time then passes the segments then remain illuminated. Similarly, if the switch 151 is actuated when the heating/hot water system is activated, then the heating/hot water system is deactivated for the rest of the activation period and the corresponding segments between the present time and the end of the activation period are switched off. As time progresses, the segments within the set activation period are progressively re-illuminated. By actuating switch 151 for a second time, the advance mode is cancelled.
  • Selecting switch 152 activates the heating/hot water system for one hour from the present time or if the heating/hot water system is already turned on, the period of activation is extended by one hour. When this is pressed, the corresponding segments are illuminated. As time passes, the segments are progressively switched off. Actuating switch 152 twice, activates the heating/hot water system for two hours (or for two extra hours) and actuating the switch 152 three times activates the heating/hot water system for three hours (or for three extra hours). Actuating the switch 152 for a fourth time cancels the extra activation of the heating/hot water system.
  • a tab 154 is provided, which can be pulled down to reveal a card with operating instructions printed thereupon.
  • a switch 153 is provided to allow a user to set the present time.
  • switch 153 When switch 153 is actuated, the current set time flashes at the increased rate.
  • the knob 110 is rotated until the flashing segment corresponds to the correct time.
  • the knob 110 is then pressed to set the correct time.

  • a series of indicators possibly in the form of illuminable segments, may be provided to indicate the current operational mode.
  • the activation periods may be set by use of the set/review switch 149. When actuated, switch 149 causes the activation periods to be displayed. A user may then set or reset the activation periods as described above except that the segment corresponding to the selected day of the week is also illuminated. The different days of the week may be selected by rotating the knob 110 past midnight, in the appropriate direction. In this embodiment it is possible to set more than two activation periods per day (three activation periods are shown in figure 3) but the activation periods may not extend past midnight.
