WM 1013-200

I just replaced the Integrated Boiler Control on a WM GV4 Series 1 to the new updated 1013-200.  Upon powering up, the power light and the tstat/circulator light come on and that is as far as it goes. I have tested the limit switches and they are closing like they should.  Any ideas are appreciated as it is getting really cold here.

new control

page 51 -- 2nd light means circulator and blower on.  Does the blower come on? Is the circulator on?  Give us some more details.



limit switches and block switch contacts closed - are for the third light.



The manual below, I believe, is the operation sequence:

In that same manual

starting on page 66 and in particular page 70 you will find troubleszhooting procedures.
