Why is VRF option no longer available?
From version v2.0.a onwards, these two system types were removed from the HVAC system type options and replaced by the system type “Split or multi-split system”. This change was made in order to simplify the HVAC system options (multisplit can be used for VRF as VRF is a type of split/multisplit system) and in order to remove ventilation from HVAC systems where the ventilation is not an integral part of the system heating/cooling strategy. If these systems are accompanied by mechanical ventilation, mechanical ventilation should now be defined at zone level, with a suitable ventilation SFP.
