Watts AERCO ADMS Series User Manual/Instruction Manual Download Page 8

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.
