Hi every one has any one out there had to change the water temp control mc12 , we have a faulty one ordered new control was told that they have replace the mc12 with AC1-5 which is not them same at all . Has any one carried this out thanks Paul

yes we did but gave up trying to configure the AC1-5 and used a Technologic controller instead. Basically the water controller is only a single stage stat so you could use more or less any similar device, Eliwell, carel, etc.
