Description
The Emerson Climate-White Rodgers 24A34-1 Single-Switch Electric Heat Sequencer is a control component in electric HVAC systems for the staged start-up of heating components. It detects approaching voltage and temperature levels and switches its internal switch to a preset value to alternate power to one group of electric heat elements, to limit current, and to provide orderly delivery of heat. This sequencer is used in the system to heat the stage and also the electrical parts.
