System is a Heatrae Sadia Megaflo Unvented Heating System.
Last year my heating (distribution around house )worked correctly until i had a plumber in working on a seperate boiler issue (Also resolved). i.e I COULD HAVE THE HEATING ON UPSTAIRS AND DOWNSTAIRS AT THE SAME TIME..... BUT NOT NOW.
Now my for my house set up.. I have a thermostat downstairs in the hallway that controls all the downstairs heating.
I also have a thermostat upstairs in the main bedroom that controls all the upstairs heating and the radiators in the bathroom.
The above all worked perfectly up until the boiler issue. The builders plumber after checking and fixing the boiler stated that he had adjusted the system so that the bathroom radiators would come on if either the upstairs or downstairs heating is switched on and yes it does that.
HOWEVER......If I swicth both the upstairs heating on and the downstairs heating on at the same time EVERYTHING goes LUKEWARM so i can have one or the other but not both at the same time.
Yes if the warranty is in date and the builder was still around i would call him direct but they are no longer around.
Incidently in the hot water tank cupboard i have three honeywell 2 port valves all set to auto.
I suspect he has rewired these or do i need to set one to manual..
Thanks in advance.
