In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Has anyone seen this “ISTA” reset control before?
I’ve been a commercial service tech for 11 years now and have never seen one of these before. It looks a lot like the Honeywell. I can’t find any info on it either. It says “Tour and Andersson” on the dial which I have dealt with before with 3-way valves.
