Abstract

A control device for a heating device includes: a thermostat having a control unit, the control unit being connected to an energy source which is used to operate the control unit. The energy source is configured to generate energy in response to the presence of temperature differences between two reference points.

First claim

What is claimed is:

1. A control device for a heating device, comprising:
a thermostat having a control unit; and
an electrical energy source connected to the control unit and electrically powering the control unit, wherein the electrical energy source generates electrical energy to electrically power the control unit in response to a presence of temperature differences between two reference points connected to the electrical energy source;
wherein one reference point detects an environmental temperature and the other reference point detects a temperature of a heating pipe, and wherein the electrical energy source includes a first module and a second module, the first module generating electrical energy to electrically power the control unit in response to a presence of a temperature difference within a first difference range, and the second module generating electrical energy to electrically power the control unit in response to a presence of a temperature difference within a second difference range, the second difference range representing greater temperature differences than the first difference range.

2. The control device as recited in claim 1 , wherein the energy source is integrally situated in the thermostat.

3. The control device as recited in claim 1 , wherein the energy source is connected to a temporary energy store.

4. The control device as recited in claim 1 , wherein the control unit is connected to an input/output unit configured for manual input and optical representation of values.

5. The control device as recited in claim 1 , wherein the control unit has a bidirectional data transmission unit for communication with at least one central control unit.

6. The control device as recited in claim 5 , wherein the data transmission unit is configured for wireless transmission.

7. The control device as recited in claim 1 , wherein the thermostat has a standard terminal for manual connection to the heating device by an operator.

8. The control device as recited in claim 1 , wherein the thermostat has a temperature sensor configured to measure the environmental temperature, the temperature sensor being connected to the control unit.

9. A system for controlling a heating device, comprising:
a central control unit; and
a control device for the heating device, the control device including: (i) a thermostat having a local control unit; and (ii) an electrical energy source connected to the local control unit and electrically powering the local control unit, wherein the electrical energy source generates electrical energy to electrically power the local control unit in response to a presence of temperature differences between two reference points connected to the electrical energy source, and wherein the local control unit has a bidirectional data transmission unit for communication with the central control unit;
wherein one reference point detects an environmental temperature and the other reference point detects a temperature of a heating pipe, and wherein the electrical energy source includes a first module and a second module, the first module generating electrical energy to electrically power the control unit in response to a presence of a temperature difference within a first difference range, and the second module generating electrical energy to electrically power the control unit in response to a presence of a temperature difference within a second difference range, the second difference range representing greater temperature differences than the first difference range.
