Hi,

I have to model floor convectors in a multifamily residential, but the
mechanical designer is foreeseing the following mode of operation: The
convector fans will not run during normal heating and air from the
convectors will rise by natural convection into the room. Only when this
kind of heating is not sufficient for loads will the fans in the
convector units start working. This will be controlled by an outside air
thermostat.

Which system would be the most suitable for this in eQuest and how to
tell the software that fans will only be operational below a certain
temperature (FYI: cooling in the same spaces will be by VRF units).

Thank you,

Omer Moltay
