Simulation an ON OFF Control Valve

1 post / 0 new


I am doing a energy simulation of a building with five rooms. The HVAC systems are composed by a dedicated ventilation unit that treats the outdoor air and interior fan coil units, one per room.
The control valve in ventilation units is tree way modulation valve and in fan coils are an ON OFF tree way valve. When I simulate the system in Trace 700, the valves in fan coils work like a modulation valve because the thermal output energy vary according to the necessities of the rooms. They should work in mode ON OFF, maximum or zero.

How can I simulate an ON OFF control valve with fan coils in Trace 700?


Many Thanks
