Simple Central Ac Thermostat Wiring Diagram Photos - This is just to give you an concept of a typical electric powered heater setup in a cut up air con and heating gadget. Notice that this one has a relay on it that has no and nc terminals. Other gadgets might also have a laptop board that has no and nc terminals, others can also have a more superior kind of board in them, but for the motive of these days’s education we're going to use this diagram. The nc terminal method that there is constantly going to be energy going via that relay to the sequencer.

However the sequencer is not energized till it gets a call for heat from the ‘w’ terminal at the thermostat. The 24 volt ‘not unusual’ twine is usually going to be live going into the sequencer, while the thermostat get a name for warmth, ‘w’ is energized, which closes the circuit at the sequencer, so as to entire the connection to the blower and the primary stage of heating. Depending on what kind and what stage sequencer you have, the second set of contacts on the sequencer may open 30-60 seconds after the first set opens. In this diagram i am the use of a 2 pole 24volt coil warmness sequencer.

Electric heaters are common in lots of break up hvac structures where it doesn’t get so cold, and additionally apart of many warmness pump structures, which they may be often called ’emergency warmth’. Electric powered heaters normally cost extra to run than warmth pumps, but are necessary whilst temperatures get so cold out of doors that the warmth pump may not be capable of hold up with the temperature. I may be explaining the fundamental wiring of an electric heater only these days, in order that folks that want a little greater hvac education at the difficulty can do so here. Observe to study my disclaimer, and except you have at the least 2 years in hvac college in conjunction with 2-three years of hvac apprenticeship schooling you need to now not attempt or depend upon this diagram at home, that is for informational purposes handiest, this is also on no account supposed for field use! In case you are in the field confer with the manufacture wiring diagram.
