Application 2033 Constant Volume with Hot Water
Reheat
In Application 2033, the controller provides a constant volume of air to the room during
occupied periods, and a lower constant volume of air to the room during unoccupied
periods. Reheat is provided by modulating a hot water valve. In order for the
application to work properly, the central air handling unit must provide pre-conditioned
air to the terminal box.

Application 2092 Slave Mode
Application 2092 is the slave mode application for the TEC (see Ordering Notes for
product numbers). Slave mode is the default application that comes up when power is
first applied to the controller. Slave mode provides no control. Its purpose is to allow
the operator to perform equipment checkout before a control application is put into
effect and to set some basic controller parameters (CTLR ADDRESS, APPLICATION,
etc.).
