I have a question about a high limit temp on a duct heater I am working on.
The high limit switch has 105 on it do you think it cuts out a 105F or 105C. I
put a temp probe just past the heat coils in the duct and it goes up to 140F
and cuts out. Its a REDD-I unit. I called the so call tech support with this
company and they say 105F but when I pulled the fuse link it was rated for
104C. What do you think? Any input would be helpful.
