ABSTRACT:
An adjustable thermostat range limit apparatus consists of a base member having a pair of adjustable temperature limit means. The thermostat range limit apparatus is attached in the proximity of a conventional thermostat so that the adjustable temperature limit means can come into contact with the temperature control level of a conventional thermostat. These adjustable temperature limit means will provide for a restriction in the temperature range in which the temperature control lever can be set.
