Nordyne 01-0843 Furnace Heat Sequencer Relay 1-110'ON 1-110'Off

The Nordyne 01-0843 Furnace heat sequencer relay is used to regulate the operation of several gas valves in a cascading heating system. This relay makes it possible to time the ignition and operation of each gas valve appropriately to give the right amount of heat and at the same time be safe. With the help of adjustable intervals of from 1 to 110 seconds for on and off of each stage, the sequencer ensures the correct heat output and avoids overheating or incorrect temperature distribution. This makes the heating systems more efficient, saves energy and gives much better and constant heat to the rooms they serve.
