Our technicians are taking precautions to ensure the health and safety of you and your family. Press “set” or “program” again to set a temperature. Generally speaking, thermostats work by using a mercury switch that is in contact with a thermometer wire to trigger a temperature-adjustment lever in response to the expansion or contraction of the wires as they are heated or cooled. Press your thermostat ring towards the wall to see more options. Sophisticated zone-controlled home climate systems divide the house into several separate areas that may each be controlled by separate settings and times on individual thermostats. It makes sense, then, that you’d have temperature controls for each of these two functions. Either way, you go there will be a digital interface for you to control (or program and forget) based on the temperature, time of day or season. So how do analog and digital thermostats work? 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. Digital thermostats have also have several advantages over mechanical, mercury thermostats. November 9, 2015 by admin Leave a Comment.
