Temperature control for an air conditioning unit

摘要

Apparatus for preventing the unwanted changing of the temperature range setting of an air conditioner unit. The shaft of a unit's thermostat is passed through a first panel and a control knob is mounted upon the distal end of the shaft. A raised second panel is placed over the first panel having an opening for rotatably receiving the body of the control knob. A radially extended arm is mounted upon the control knob so that it swings over an arcuate path of travel between the panels as the shaft turns. Spaced apart holes are formed in one of the panels along the arcuate path of travel and stop pins are removably mounted in said holes on either side of the arm to control the range of movement of the shaft and thus the operating range of the air conditioner.
