To give an idea:\r\n```\r\n  230 seconds for a 1-zone model, central thermostat\r\n  340 seconds for a 2-zone model, central thermostat + TRV, but setpoint TRV zero\r\n2240 seconds for a 2-zone model, central thermostat + TRV\r\n```\r\nQuestion is, whether it's caused by the choice for a `..Fluid.Actuators.Valves.TwoWayQuickOpening` or the accompagning `k`-value of the `PID`. Any experience on this @arnoutaertgeerts ?"}}
