Triangle tube Solo 110 pumps wont shut off

Paul_34

I went on a service call today on a triangle tube solo 110 and the complaint was very hot domestic water. Get there and boiler was cycling off of high limit. The dhw and radiant pump was running with no dhw and radiant call. This house was it by lightning this morning.

Paul,

I would start by powering down the unit and resetting it. Then I would pull the heat and dhw switch wires to be sure you don't have a smoked switch somewhere else in the system. I would also go through the setup codes and make sure they are at factory defaults.

Chances are, the lightning smoked the controller and you need a new one.

You may need more than a new control.  No telling what lightning will zap when it starts flying around -- so do try the wire pulling that Zman suggested before swapping out parts.



While you're at it, if you have a good multimeter (reading over 1 megohm) or a megger, check as much of the wiring as you can for grounds and shorts that shouldn't be there.

1.21 jigawatts takes out a lot of things...Great Scott!

 Happened  to a customer of mine last week. Took out the Taco sr506, the Honeywell 7224 boiler limit and the Riello primary..... all smoked.
