Q: we currently have l4006e1067, would this perform the same function only with both high & low limits?
Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffThe primary differences are that this part (L4081A1023) is a multiple aquastat controller and L4006E1067 is a manual reset unit (no differential temperature).
