There is a lot of work being done on ApacheHVAC this year so I will mention this to see if it can be included in the plans.I would like to propose a small change.
It would be a good thing to have oversize factor field in the terminals: radiators, ch. ceilings and other which will give possibility to have oversizing either in the boilers either on the terminals side.
I see what you mean, have logged this with the team. An easier workaround (rather than having to ok the dialog then go back in) if you enter the value then click on any other input box it will accept your previous input and you can then move on to the next tab.Small Problem: In the Boiler window - there are tabs: Rated, Design and Oper. Parameters.
When I tried to change the capacity in Tab - Rated and switched to Design Tab it didn't accept the value. I had to click OK and to close the window in order to enter the value. The same is with the Design Tab when I tried to change the oversizing of the boiler - it will not save the new value unless you close the window with OK (without changing the Tabs).
