minimum boiler temp

[geochurchi]

Hi, I have a Buderus G124X propane fired boiler cotrolled by a Taco PC 700-2 boiler reset setting on control is set at 140 for min.boiler temp but the minimum temp is running around 115, I can't figure out which setting on the control affect the minimum temp, Taco tech support always refers me back to the reset ratio graph which can not understand. anybody have any ideas?

Can't answer your question, but I have been looking to install a Taco 700 in my house. Have you been happy with it?

I like the control except for the fact that I can not get the min. boiler temp up to factory specs. I am using the PC700-2 with ZCV 406 EXP which I really liked because it simplified the control wiring and made a nice neat install. I also read that Telmak (spelling)makes the PC 700-2 for Taco and that that brand is about $100.00 cheaper. I'll get it figured out at some point.
