This 15SH2-style sequencer is a replacement control for HVAC technicians and electric-heating service professionals working on fan and heat sequencing functions. It helps coordinate staged operation in compatible electric heating applications.
The sequencer uses a 24V input and is designed as a direct replacement for most fan and heat sequencing functions. In a multi-timing sequencer, M1 and M2 contacts turn on first and turn off last. Subsequent stages have a five-second on delay unless they operate together. It measures 2.75 in. wide, 3.875 in. deep, and 2.375 in. high.
Key Features:
- 24V input control: Supports systems that use a 24V control input.
- Staged sequencing: Provides a five-second delay between subsequent stages when they do not operate together.
- M1-M2 contact timing: Keeps M1 and M2 contacts first to turn on and last to turn off in multi-timing operation.
- Replacement-style design: Helps service professionals replace compatible fan and heat sequencing controls.
Choose this sequencer for compatible fan and electric-heat sequencing service where 24V input control and staged timing are required.
