Introduction 

The DEMA 844P Laundry Master dispensing system has been designed to accurately deliver chemical 
product to commercial laundry machines.  The 844P uses the proven DEMA Quick Change peristaltic 
pumps to deliver the chemical product to the laundry machine pocket.  The Quick Change pumps and 
main control are mounted in a durable and attractive ABS enclosure designed to provide easy access to 
the various components inside. 
 
The various electronic components of the DEMA 844P Laundry Master use a “plug and play” concept to 
provide easy setup.  The heart of the 844P is the IQ-85 electronic control board that provides 30 wash 
formula capability.  The IQ-85 is mounted in the ABS enclosure with the display and buttons available on 
the front panel.  Along with the IQ-85 is the self contained Signal Transfer Unit (STU), which can be 
mounted at the laundry machine to receive trigger signals.  Additionally, a handheld Enhanced Digital 
Select Module (EDSM) is available to allow the user to interface with the system remotely.  Both the STU 
and the EDSM are connected to the IQ-85 via a low voltage communication cable.
