So how does a thermostat work? Digital Thermostat Electronic thermostat or digital thermostats are much more commonly found now. Digital thermostats have also have several advantages over mechanical, mercury thermostats. For instance: They’re much more accurate. It detects by sensing the air temperature, switches on when the heating of air temperature falls below the thermostat setting and switches off when the set temperature has reached. You will also be missing out on the Room Sensors that come with the product. Modern thermostats are capable of controlling both heating and air conditioning, and they can be programmed based on the energy needs of the home. For those of you who don’t know, a millivolt system uses a thermocouple / thermopile with a standing (constant) pilot flame to generate a tiny “millivolt” signal that is used to control the furnace rather than the 24v signal modern thermostats use. When the temperature goes up, the metal expands, when the temperature drops, the metal constricts. If all you want is to be able to program the heat and maybe cooling then this should be fairly easy.
