Working product at a good price
I bought this 24vac transformer for an old furnace in a rental house of mine to replace the old one that was not working. Studied the installation instructions for a few minutes, installed it, and boom, it worked.

Bought two, would buy again
I bought this to power my smart thermostats. I also figured it could be a good backup unit if ever my boiler transformer zonked out. Easy install. I like it has dual mount capabilities. Straight forward. I liked it so much I went ahead and bought a second one and replaced boiler unit. Both installed onto junction boxes. So I expect many years of reliable service. Hopefully they will last so long I will forget I have them.

Product Q&A
1 Question1 Question
Q: I am replacing 3 B&G zone valves (old style M1) with 3 new B&G CT-24 zone valves, after installing, the 24V transformer on the Honeywell L8148E aquastat burned up. The replacement aquastat recommends using a AT72D external transformer to power more than two zone valves along with a vent damper and gas controls. The new zone valves have a .6A rating. I am looking for advice on how to wire the external transformer with the zone valves
