Hi,
I am new to forum so apologies if this question has been covered. I have searched the net and this forum and just seem to get more and more confused!
I have what I think must be a very common system. 18kW boiler feeding Y plan mid position valve, radiators with TRV's and vented cylinder. There are a few non TRV radiators and no bypass valve. Controls are non Vaillant and consist of a two channel time clock and mechanical room thermometer. Cylinder has standard type clamp on stat.
I would like to operate the system as follows.
CH - 5/2 timed control with flow temperature set by me depending on weather (happy to use existing control on boiler)
DHW - 5/2 timed control with flow temperature set at 82 degrees celsius.
Question is - if I upgrade to VR65/timeswitch 140/VRT30 will I get this level of control?
What happens in the mid position when Ch and DHW are calling? Do I need to revert to a non mid either DHW or CH situation to have two different flow temperatures for the two circuits.
Seems simple in theory but I am having problems getting a straight answer!
Thanks for reading
