Abstract
An improved thermostat having two modes of operation selected by a pressure signal from a central source, which includes a separate set point for each mode of operation. Each set point has a scale which is clearly visible without removal of any parts of the thermostat. Each set point is also adjustable either by an adjuster that can be operated by occupants or only by authorized personnel having a tool fitting the opening in the set point adjustor. Adjustors can be provided with restrictors which limit set point adjustment to a predetermined range of temperatures and which can be adjustable by authorized personnel, or can be factory set.
