Technical Data Sheet

ADMS™ Smart Water Tempering System

The AERCO Digital Mixing Station (ADMS™) is a smart water tempering system that allows temperature controlled distribution of potable hot water throughout the loop. The lead-free1 ADMS™ regulates distribution temperature within ±2ºF in accordance to ASSE 1017 at all flow conditions (including low and zero demand periods) and its temperature setting is field configured without the use of special software and laptop. The building automation system (BAS) ready ADMS™ can be configured with strainers, building recirculation pump and Flow/BTU monitor package to allow facilities managers to remotely monitor and control distribution wa-ter temperatures along with monitoring of flow and energy consumption.

Unlike the traditional thermostatic mixing valves, it is capable of func-tioning under varying pressure differentials across the inlets.

Features

• Configurable on site without special software and laptop

• Tight temperature control of ±2ºF in accordance with ASSE 1017

• Control ±2°F during periods of low/zero demand

• 3.5” full-color, user-selectable touch screen display

• User programmable high-temperature sanitization mode

• Cold water failsafe with manual override feature to set mixed outlet temperature

• Settings can be adjusted/monitored at the controller or remotely via BACNET or Modbus interface

• Displays pressure, temperature and flow/BTU data

• Pass code protected for security

• User programmable high temperature alarm

Warning ADMS™ provides user-directed control and monitoring of water distribution systems. It is the user’s responsibility to select and maintain water temperatures that are safe and appropriate for the water system users and facility. ADMS’s Sanitization mode is intended for use as part of a user-directed, controlled and supervised protocol that has been safely and properly designed.

It is recommended to install ADMS™ as part of a ASSE compliant water distribution system, including point-of-use mixings valves.

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.

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.

Always read and follow User Guide & Instruction Manual and all product warnings and labels, and comply with all governmental and safety requirements.

Typical Specification Lead free digital water temperature control and monitoring system shall feature full-color touchscreen inter-face which is configurable on location and does not require factory pre-programming. System shall control water temperature to ±2°F in accordance with ASSE 1017 and during periods of low/zero demand and feature a user-programmable high temperature alarm.
