Nordyne 01-0840 Sequencer 1-20 On, 40-110 Off

The Nordyne 01-0840 Sequencer is used to control the staged operation of electrical heating elements. Its main role is to power heating circuits sequentially within the designated temperature ranges and go on between 1-20°F and go off between 40°F - 110°F. The operation of the sequencer is that the temperature is measured, and electrical contacts are turned on or off. In HVAC systems, it controls the activation of the elements, assists in the uniform distribution of heat, and minimizes excessive current usage, which contributes to the realization of a smooth and consistent temperature regulation.
