Re: [EnergyPlus_Support] Terminal equipment don't work

["Michael J. Witte" <mjwitte@xxxxxxxx>]

There are many possible reasons:

1.  Thermostat type must be SINGLE HEATING COOLING SETPOINT or DUAL SETPOINT 
WITH DEADBAND.

2.  Are the reheat coils scheduled on?

3.  Are the reheat coils large enough?

4.  If the reheat coils are hot water, is the hot water loop active?  Boiler 
large enough?

Compare your model with the TermReheat.idf example file to see you have similar 
kinds of control components.
