HVAC tab in model data - Compact HVAC
When using some Compact HVAC options you may need to specify a zone to be the control zone, i.e. the conditions in this single zone will be used to decide the operation of the HVAC system as a whole. The control zone checkboxes are only visible at zone level and for certain system types.
To define which zone is the control zone for one of the 4 system types requiring this setting, you should navigate to the zone in question and check the check box as described below.
Check this if the current zone provides the conditions used to control the operation of the Unitary multizone system. You should normally select a zone which is representative in terms of building temperature. In a dwelling, the central circulation area (hall/landing) is often a good location for the thermostat. However it is also important to note that if the zone selected as thermostatic control has no cooling selected then cooling for the whole building will not operate. The same applies to heating. So the zone selected here should also be representative in terms of the HVAC systems used to serve it.
The zone to be used to control humidification in Compact VAV, CAV and Unitary multizone systems.
The zone to be used to control dehumidification in Compact VAV, CAV and Unitary multizone systems.
It is now possible to use the same zone for humidification and dehumidification.
