Excellent Delivery and Service
Parts delivered in a few days, great website to search and find information about the products. I use Johnson Controls 350 series controllers for my wood burning boilers. I'll order again from Supply House.

Replacement
Purchased to replace failed thermostat. Can't really comment on functionality. It replaced one that failed after 3 years. However, I have others that have been in service for 25 years.
