Mavi,
I faced this same situation at one point and was able to use Type505
by turning it around backwards. Fundamentally, when Type505 refers to
"heating," it is heating the air stream and cooling the water stream.
When it is "cooling" it is cooling the air and heating the water stream.
In your case, "heating" means heating the water and cooling the air. So
if you treat Type505's "cooling" control signal as though it were your
"heating" control signal, it should work fine.
I believe that in upcoming Tess Libraries 17, there is a specific
component for what you are trying to do but I am not aware of its status
at the moment.
Best,
david
