Important Safety Information
OMM-0126-0A Page 3 of 71

The ADMS is electronic water mixing system providing user-directed control and monitoring of water
distribution systems. ADMS includes an electronic Control Module featuring a color touchscreen digital
display to select desired outlet water temperature, an electronically actuated valve that mixes hot water
with cold water, temperature sensors (plus a quick response temperature sensor), pressure sensors,
check valves, and a recirculation pump to maintain the recirculation loop temperature (reducing wait
time for tempered water to reach point-of-use fixtures, saving water and energy). The ADMS monitors
hot supply inlet temperature, hot supply pressure, mixed outlet temperature, mixed outlet pressure,
mixed outlet flow rate (optional), return temperature, and return pressure, to help maintain the desired
outlet water temperature. ADMS also features a user programmable high temperature Sanitization mode
to help limit water-borne bacteria as part of a user-directed and controlled thermal eradication protocol.
The ADMS Control Module supports building automation systems (BAS) communication with BACnet®
IP, BACnet®MSTP, and Modbus®protocols, allowing remote programming and data viewing.
Installation and adjustment of the ADMS are the responsibility of the owner and installer and must be
done by qualified personnel in accordance with the manufacturer’s instructions, and complying with all
governmental requirements, building and construction codes and standards. It is recommended to install
ADMS as part of an ASSE compliant water distribution system, including mixing valves and/or tempera-
ture limiting devices at all point-of-use fixtures (faucets, sinks, tubs, showers, etc.) that are approved
to ASSE 1016, 1069, 1070 and 1071. The owner and user of the ADMS is responsible for selecting and
installing the product in an appropriate water distribution system, proper sizing, maintaining proper
water quality/condition, and deciding what temperature is safe and appropriate for the water distribution
users and facility.

Control Module and Digital Display
Description of Controls and Functions
The following sections generally outline and describe the controls and functions of the ADMS Control
Module you will experience when using the digital display. See “Set Up and Programming” section of
this Manual for use instructions.
The intelligence running the ADMS is contained within a Control Module. The color and touch screen
digital display allows the user to view temperatures, pressures, flow rates throughout the system, and
to configure the controls. The following sections describe and explain the user interface to assist in
navigating and configuring the control.
After power up, the “Attention!” screen (shown below) will appear. You have 60 seconds to begin
system navigation.
The Control will begin mixing operation after 60 seconds. The "Attention" message will appear again
after 10 seconds of inactivity until the 60 seconds time has elapsed.
