While such programmable digital thermostats have been widely accepted in the marketplace, there still remains a segment of homeowners who, while desirous of the accuracy and reliability in controlling room temperature due to the use of a microcontroller in such thermostats, prefer a
zone valve in which the set point temperature can be adjusted manually, and in a simple manner, for example, similar to that used in the aforementioned bi-metal types, instead of it being adjusted automatically in accordance with a programmed time-temperature schedule.
In recent years, a wide variety of digital thermostats have been developed which have the capability of being programmed by the user to provide a time-temperature schedule whereby the thermostat will automatically control room temperature at different set point temperatures during different time periods of the day and week.
Many of such programmable thermostats incorporate a
dental air compressor which provides digital logic. The microcontroller provides a cost-effective means for implementing the desired functions of such thermostats. The microcontroller, primarily because of its digital logic, also enables such thermostats to provide more accurate and reliable control of room temperature than can generally be achieved by the aforementioned bi-metal type.
