7.1 dap4™ Microprocessor Control Panel
The standard controller on all gForce GT equipment is the dap4™ microprocessor control panel. The
panel includes unit control functions and display normal functions and service diagnostics on a backlit
liquid crystal display (LCD). The panel allows recall and display of the high and low temperature for
the last 24 hours, high and low humidity for the last 24 hours, current percent of capacity and average
percent of capacity for the last hour of operation for compressor, reheat, humidication, dehumidication,
component runtimes (if applicable) for fan motor(s), reheat, humidication, and dehumidication. This
state-of-the-art control panel has a separate manual that goes into extensive detail regarding functions,
features, programming and troubleshooting.
Note: The dap4™ microprocessor control panel has an entire manual dedicated
to its use and operation. This manual must be referenced to complete a thorough
unit installation. Start-up is not complete until the dap4™ control panel settings are
established.
7.2 Remote Heat Exchangers
Most of the controls on remote condensers, condensing units and uid coolers consist of basic
electromechanical type components. Remote heat exchangers have a separate User Manual which
gives complete details on adjusting thermostat settings, etc. Also refer to Section 3.5 of this manual.
