Hi, It might be due to the fact that you cannot have an Inlet Water Temperature (inlet3) below the Room temperature (inlet 1) with this component. Inlet water temperature > Room temperature +0.5 An idea is thus to control the inlet3 to max(inlet temperature, room temperature +0.5) Best regards, David BLANDIN CARDONNEL Ingénierie De : trnsys-users-bounces@cae.wisc.edu [mailto:trnsys-users-bounces@cae.wisc.edu] De la part de Richard Thygesen Hi. I’m trying to use the radiator model type 1231 together with type 56. Is it possible to connect air temperatures from a zone in type 56 to the type 1231 room temperature input? When I do that I get a run time error. Best regards |
