What it is
The Honeywell L641B1004 is a pipe-mounted thermostat with a low-limit range of 2°C to 40°C, part of Honeywell's L641 series of pipe stats. It senses pipe surface temperature and, in low-limit duty, operates when the pipe falls to the set point. It is used to bring on a boiler, pump or secondary circuit as pipe temperature drops.
Before you order
- Confirm a low-limit function is what the circuit needs: a low-limit stat operates on a fall in pipe temperature, not a rise.
- Check the pipework at the intended mounting point is accessible and suitable for a surface-mounted pipe stat.
- Verify the 2°C to 40°C range covers the set point required for the application.
