This 24V fan and heat sequencer is for HVAC professionals servicing electric heating systems with multi-stage fan and heat sequencing. It coordinates the order of operating stages to support controlled system operation.
The sequencer uses a 24-volt input. In a multi-timing sequencer arrangement, the M1-M2 control contacts turn on first and turn off last. Subsequent stages have a five-second on delay unless stages are designed to operate together. The unit measures 2.75 x 3.875 x 2.375 inches.
Key Features:
- 24V input: Matches systems that use a 24-volt control input.
- M1-M2 contact sequence: Provides first-on and last-off operation for these control contacts in a multi-timing setup.
- Five-second stage delay: Spaces activation of subsequent stages when they do not operate together.
- Fan and heat sequencing: Supports replacement of most fan and heat sequencing functions.
Choose this sequencer for compatible multi-stage electric heat applications requiring 24V control input and timed fan and heat stage operation.
