Revision history [back]

Hello good people, I have a system running on VRF system. I changed the terminal fan from On/Off to fan:System model because i wanted to apply variable speed operation/multiple speed to the fan air supply. The system is working and the mass flow rate variation is available in .eso. However the system doesn't calculate fan energy in that regard. does anyone have an idea how to go past it? Either by incorporating a new technique or how to calculate the energy.
