Abstract
Abstract Apparatus for controlling a heat generating device having automatic adjustment of water temperature to heating requirements, and also for protecting such devices from being switched "on" and "off" too frequently, includes a control relay or a main relay having a "pause" imprint contact for switching "off" and an "on" contact, as well as a chronometric device for measuring how long the heat generating device is switched "on" and for setting an "off" pause imprint interval which is inversely variable according to the measured length of time the heat generating device is switched "on".

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
85 words
Equipment for controlling a heat generating device having automatic adjustment of water temperature to heating requirements, and for protecting said device from being switched "on" and "off" too frequently, comprising: a control relay or main relay having a "pause" imprint contact for switching "off" and an "on" contact, and a chronometric device for measuring how long the device is switched "on" and for setting an "off" pause imprint interval which is inversely variable according to the measured length of time the device is switched "on".
Claim 2
Dependent Claim
85 words
Equipment for controlling a heat generating device having automatic adjustment of water temperature to heating requirements, and for protecting said device from being switched "on" and "off" too frequently, comprising: a control relay or main relay having a "pause" imprint contact for switching "off" and an "on" contact, and a chronometric device for measuring how long the device is switched "on" and for setting an "off" pause imprint interval which is inversely variable according to the measured length of time the device is switched "on".
Claim 3
Dependent Claim
33 words
Equipment as claimed in claim 1 wherein a maximum pause interval is pre-programmed which is shortened by a constant multiple of the length of time for which the burner has been switched on.
Claim 4
Dependent Claim
38 words
Equipment as claimed in claim 1 wherein in cases involving multi-stage or adjustable burner systems, the pause interval and/or the burner output is variable depending on the length of time for which the burner has been switched on.
Claim 5
Dependent Claim
36 words
Equipment as claimed in claim 3 wherein the burner can be pre-set to operate for one or a number of lengths of time, such that the burner is turned down as soon as these are exceeded.
Claim 6
Dependent Claim
25 words
Equipment as claimed in claim 4 wherein upon reaching a pause interval of "0", the burner is turned up to a higher level of output.
Claim 7
Dependent Claim
18 words
Equipment as claimed in claim 2 wherein the maximum pause interval and/or the constant multiple can be adjusted.
Claim 8
Dependent Claim
27 words
Equipment as claimed in claim 6 wherein the maximum pause interval and/or the constant multiple are variable depending on the time of day or on the temperature.
Claim 9
Dependent Claim
18 words
Equipment as claimed in claim 1, further comprising that there is a bridging contact to the pause contact.
Claim 10
Dependent Claim
17 words
Equipment as claimed in claim 8 wherein the bridging contact is controlled by a thermostat and/or timer.
Claim 11
Independent Claim
88 words
A method for controlling a heat generating device having automatic adjustment of water temperature to heating requirements and for protecting said device from being switched "on" and "off" too frequently, comprising the steps of: controlling a relay or main relay having an "off" (pause) imprint upon contact and an "on" contact; measuring with a chronometric device how long the heat generating device is switched "on"; and setting an "off" (pause) imprint interval which is inversely variable according to the measured length of time the device is switched "on".
Claim 12
Independent Claim
88 words
A method for controlling a heat generating device having automatic adjustment of water temperature to heating requirements and for protecting said device from being switched "on" and "off" too frequently, comprising the steps of: controlling a relay or main relay having an "off" (pause) imprint upon contact and an "on" contact; measuring with a chronometric device how long the heat generating device is switched "on"; and setting an "off" (pause) imprint interval which is inversely variable according to the measured length of time the device is switched "on".
Claim 13
Dependent Claim
34 words
A method as claimed in claim 10 wherein a maximum pause interval is pre-programmed which is shortened by a constant multiple of the length of time for which the burner has been switched on.
Claim 14
Dependent Claim
39 words
A method as claimed in claim 10 wherein, in cases involving multi-stage or adjustable burner systems, the pause interval and/or the burner output is varied depending on the length of time for which the burner has been switched on.
Claim 15
Dependent Claim
35 words
A method as claimed in claim 12 wherein the burner pre-set to operate for one or a number of lengths of time, such that the burner is turned down as soon as these are exceeded.
Claim 16
Dependent Claim
26 words
A method as claimed in claim 13 wherein upon reaching a pause interval of "0", the burner is turned up to a higher level of output.
Claim 17
Dependent Claim
16 words
A method as claimed in claim 11 wherein the maximum pause interval and/or the constant adjusted.
Claim 18
Dependent Claim
28 words
A method as claimed in claim 15 wherein the maximum pause interval and/or the constant multiple are varied depending on the time of day or on the temperature.
Claim 19
Dependent Claim
17 words
A method as claimed in claim 10 further comprising effecting a bridging contact to the pause contact.
Claim 20
Dependent Claim
17 words
A method as claimed in claim 17 comprising effecting the bridging contact by a thermostat and/or timer.
