Munchkin 925 control?

Andy Michl_2

I was wondering if you can tell by the model number on the Munchkins which ones are the Vision Systems?

All 925 controls come ready to plug in the wire for vision control expansion. The key is that you have munchkins with 925 controls.

What all does the Vision control do?

925s

we have about 35 vision controls in and running. The vision consists of an outside sensor, dwh sensor,and dwh pump leads. This control modulates the low temp zone, and prioritizes dwh production. It also ramps up the boiler temp to 190 deg for domestic water production. It really integrates the modulating burner with the in/outdoor system modulation. It is a site to see. The boiler just sits there and coasts.

how long have you been using the vision system? who certified you? have you had any serious problems?

I was certified at the factory. I have seen no problems with the vision control. The 925 is a huge improvement over the old control. It seems to have eliminated the annoying pressure switch lockouts. Since the burner modulates based on the aquastat setting you lose some burner modulation when you use some one elses in/outdoor control. The vision integrates both burner modulation and system modulation. It is trick. No need for all the external wiring needed when adding a tekmar. Get yourself trained and try it. You'll like it.
