Application 2290: Heat Pump ControlIer Multi-Stage
Slave Mode
Application 2290 is the slave mode application for the Heat Pump Controller—Multi-Stage
(P/N 540-505). Slave mode is the default application that comes up when power is first
applied to the controller. Slave mode provides no control. lts 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, APPLlCATlON, etc.).
Using the Controller as a Point Extension Device
lf the controller is used only as a point extension device with no control application in effect,
its application must be set to slave mode and the points must be unbundled at the field panel.
All of these points must be controlled from the field panel in order to be used.
