Abstract

In an electronic thermostat timer having a time-keeping switch and having a thermostat, having an optoelectronic display (6) arranged at the front side of the housing for the time of day, the switching times and the switching temperatures, having a manual, key-shaped input device (7) for the time of day, the switching times and the switching temperatures in a common housing (1), the housing (1) is provided with a quadratic cross section, particularly having the edge dimensions 60×60 mm. A cylindrical clockface dial (3) is provided at the front side (2) of the housing (1), the outer circumference of said cylindrical clockface dial partially projecting beyond the sides (17) of the housing (1). A thermostat module (5) that is covered by a housing cover (10) is arranged at the back side (4) of the housing (1).

Claims

1. An electronic thermostat timer having in a common housing a thermostat, an optoelectronic display means arranged at a front side of the temperatures, and a keyboard for manual input of the time of day, the switching times and the switching temperature, comprising:

the housing having a quadratic cross section;

a cylindrical clockface dial at the front side of the housing, an outer circumference of said cylindrical clockface dial partially projecting beyond sides of the housing; and

a thermostat module, which is covered by a housing cover, at a back side of the housing.

2. The thermostat timer according to claim 1, wherein the clockface dial is rotatably seated and secured vis-a-vis the housing.

3. The thermostat timer according to claim 2, wherein the clockface dial is rotatably seated and fastened vis-a-vis the housing and/or installation terminals of the thermostat timer in latching fashion.

4. The thermostat timer according to claim 2, wherein the clockface dial is rotatably seated and secured vis-a-vis the housing in a range of approximately 90°

.

5. The thermostat timer according to claim 1, wherein the thermostat module has an integrated temperature sensor and/or a remote temperature sensor.

6. The thermostat timer according to claim 5, wherein connection of a remote temperature sensor is located at the back side of the housing cover.

7. The thermostat timer according to claim 1, wherein the display means displays the time of day, the switching time, the switching temperature, actual temperature and power reserve of the thermostat timer.

8. The thermostat timer according to claim 1, wherein the housing has a quadratic cross section with edge dimensions of 60×

60 mm.

9. The thermostat timer according to claim 3, wherein the clockface dial is rotatably seated and secured vis-a-vis the housing in a range of approximately 90°
