SECTION 7: onAER SETUP

7.1 INTRODUCTION

AERCO has developed new connectivity capabilities to make its IoT offering, onAER, easier for
its broad customer base to implement. The onAER feature lets you monitor your AERCO boilers
and water heaters remotely. As in the past, AERCO has taken precautions to make onAER
secure for both the customer's heating equipment and networks.
All Benchmark boilers include AERCO's onAER feature.
onAER communication can be established in one of two ways:
Through an Ethernet cable from the site's network. This is plugged into the WIZnet
card on the unit's I/O board. This card is standard equipment on all Benchmark boilers.
Wirelessly via Wi-Fi. This solution requires the purchase and installation of the optional
AERCO Wi-Fi module (P/N 24526-1). This module is then connected directly to the
boiler's I/O board, eliminating the need for both the Ethernet cable and the WIZnet card.
The sections below provide instructions for implementing only the first option, enabling
communication through an Ethernet cable connected to the site's network. If you ordered a
Benchmark boiler with the Wi-Fi module, it is included in a separate container inside the unit's
shipping container. The instructions for installing both the Wi-Fi module are in Technical
Instruction document TID-0178, included with the Wi-Fi module.
If you did not order the Wi-Fi module but are now interested in it, contact your AERCO
representative and ask about purchasing the Wi-Fi module (P/N 24526-TAB).

7.1.1 Connecting the Ethernet Cable

Connecting The Ethernet Cable Instructions
1. Connect a CAT 5 or better Ethernet cable to the wall jack or box provided at the site.
2. Route the Ethernet cable to the I/O box, avoiding hot locations.
3. Route the Ethernet cable into the I/O box through one of the plastic grommets on the side
of the I/O box.
4. Connect the Ethernet cable to the Ethernet jack in the I/O box (tab down). See Figure 7-1.
