Issue:

Cooling-only Tracker EMTK, but VariTrac II CCP is trying to put the Voyager into heating

Resolution:

Problem:
On a site with a cooling-only Tracker EMTK, the VariTrac II CCP is trying to put the Voyager into heating mode.

Solution:
This will happen if enough VAV boxes call for heating. The CCP will call for heating regardless of the configuration of the Voyager. Specifying the Voyager as cooling-only in the CCP editor does not prevent the CCP from going into heating. You can avoid the heating mode only by setting the heating setpoints very low or by setting a large heating offset.
