[Equest-users] Using PSZ as DOAS?

[Elizabeth Gillmor via Equest-users]

Hi Michael,
I have always used a Powered Induction Unit system type for DOAS systems.
 (Or standard Induction Unit system if CHW instead of DX.)  This should
give you the control and heat source capability that you need.

Good luck!
