Mini-dap4 Microprocessor Control Controller

The standard controller on all DAP equipment is the Mini-dap4 microprocessor controller. The controller
includes unit controller and a remote display. Normal functions and service diagnostics is accessed by
the remote graphic touch display (dap4Touch). The controller 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,
humidification, dehumidification, component runtimes (if applicable) for fan motor(s), reheat,
humidification, and dehumidification. This state-of-the-art controller has a separate manual that goes
into extensive detail regarding functions, features, programming and troubleshooting.

Optional Expanded dap4 Microprocessor Controller

The Expanded dap4 microprocessor controller is available as an upgrade from the Mini-dap4 and offers
additional features and additional analog inputs/outputs. There is a separate manual with extensive
detail regarding the functions, features, programming
and troubleshooting.

Optional Thermostat

For installations not requiring close environmental control, a single stage cooling thermostat is
available. Units with either humidifiers and/or electric reheat require Mini-dap4 or Expanded dap4.

Remote Heat Exchangers

Most of the controls on remote condensers, condensing units or fluid 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
Auxiliary Control Wiring.
NOTICE: The Mini-dap4 microprocessor controller has an entire manual
dedicated to its use and operation. This manual must be referenced to
complete a thorough unit installation. Startup is not complete until the Mini-
dap4 controller settings are established.
NOTICE: The Expanded dap4 microprocessor controller panel has an entire
manual dedicated to its use with detailed operation functions, features, and
parameter settings. This manual must be referenced to complete a thorough
unit installation. Startup is not complete until the dap4 controller settings are
established.
