CHS Series Controller and Display │Slant Fin Corp.
1.0 INTRODUCTION
The Controller and Display, together, form the control system of the Slant/Fin CHS boiler. All control
configuration parameters are stored in non-volatile memory in the CHS controller. Access to controller status
and configuration is achieved with the display. Interaction with the display is performed by physically touching
the buttons on the display keypad. Communication between the CHS controller and display is via EIA-485
interface using the Modbus RTU protocol.
When the appliance is powered there is a brief interval while the display retrieves data from the boiler control.
The display then shows the Home Screen (Summary screen) similar to the one depicted in Figure 1-2. The Home
Screen provides a summary of the overall operational status of the boiler. A series of menus, entered by pressing
the “i-Information” button, provide access to all boiler configuration parameters, information and diagnostics.
