I have a just installed a brand new Mira Advance ATL thermostatic

Customer Question

I have a just installed a brand new Mira Advance ATL thermostatic shower in place of an old mira advance. One on one replacement. I have purged the shower as requested and tried to commision it but I get a pulsed output of water both high low lights flashing rapidly and eventually it shuts down with water supply and reset lights on. I should also say that when purging the shower water comes out of the air bleed button.

Good morning,

Sorry to hear that.

The very first thing you need to do is to be sure the water valves are fully on. Also that there is indeed good pressure because that will cause this error.

If that is all good and you can verify that, then the new unit is likely defective and will unfortunately need to be repaired or if it were me... I would exchange it since it is brand new.

If you send me the full model # I will check into this further, but I have seen this a few times now:-)

I will stick with you on this but Since this question may continue for some time, if you will rate my service as good or better
before you close this window, the system here will allow me to schedule free follow ups with you
so your question wont close or time out and you can contact me anytime at no additional cost.
Thank you
Tech Michael
