Rated 4 out of 5 by Worked as expected This was used to replace a similar but earlier model Honeywell cylinder stat. This was selected because the dimensions are the same as the earlier model meaning the cut-out in the cylinder insulation would be the correct size. This unit is supplied with a curtain wire type strap but it has a hole to allow it to be used with a steel band type strap. I used the steel band strap from the old installation, which worked fine. The terminals are easily accessible and an improvement on the previous model. The cable clamp is easy to access. 3 Aug 2013
Rated 5 out of 5 by Honeywell L641A Cylinder Stat. My old Stat that I was using has been on my cylinder since 1966,and worked fine for all this time,but it had just started to play up. I decided to read some reviews on Stats. The Honeywell L641A had very good reviews so I bought one. I had it fitted and it has been working correctly and I am extremely happy with my choice. 10 Mar 2013
