Ac Thermostats

Thermostats use different types of sensors to measure the temperature. In one form, the mechanical thermostat, a in the form of a coil directly operates electrical contacts that control the heating or cooling source. Electronic thermostats, instead, use a thirmistor or other semiconductor sensor that requires amplification and processing to control the heating or cooling equipment. A thermostat is an example of a "bang  bang controller" as the heating or cooling equipment output is not proportional to the difference between actual temperature and the temperature setpoint. Instead, the heating or cooling equipment runs at full capacity until the set temperature is reached, then shuts off. Increasing the difference between the thermostat setting and the desired temperature therefore does not change the time to achieve the desired temperature. The rate at which the target system temperature can change is determined both by the capacity of the heating or cooling equipment to respectively add or remove heat to or from a target system and the capacity of the target system to store heat.

Love this thermostat, much better than any i could find in the local stores. I like the large very easy to read display especially with the backlight. The controls are simple and it just looks good hanging on the wall. Not something you usually think about for a thermostat, but this guy just has really nice lines and design to it. Would recommend definitely.
