Abstract

The invention involves a system for the control of the temperature of a medium within a space by utilizing a temperature-modifying device. It may include a programmable controller connected for controlling a thermal output of the temperature-modifying device to achieve the desired temperature, and an interface connected for providing information to and from the programmable controller, the interface having at least one substantially linearly moveable member with at least a position for setting a program within the programmable controller and setting the programmable controller to control the temperature-modifying device.

Claims

1. An apparatus for the control of the temperature of a medium within a space by utilizing a temperature-modifying device, said apparatus comprising:

a controller connected for controlling a thermal output of said temperature-modifying device to achieve said desired temperature, and
