Aisha,<br>
without seeing your project, there isn't really any way of telling
why the controls aren't working. You should send your project
(*.tpf), the buiding file (*.b17) and any other files needed in
order to run the project to your distributor for assistance.<br>
<br>
If you only have to cool your building then you can use the blower
that is part of Type651 as the system fan. If you have a need to
provide heating using a furnace or an electric coil then I would
recommend that you set the Type651 fan power to zero and use a
Type112 as the system fan. The system fan will run whenever there is
a call for either heating or cooling.<br>
kind regards,<br>
David<br>
