The Hoffman A.C. Monitor
The Hoffman A.C. Monitor is a Windows
®
application for the complete management of Hoffman
air conditioners. The initial air conditioner settings; cooling/heating set-points, cooling/heating
differential and high/low temperature alarm set-points are pre-programmed at the factory, but
can be locally or remotely adjusted by the user. Alarms are output from the air conditioner relay
contacts and also can be accessed through an Ethernet network connection. A USB serial
connection is provided on the air conditioner to configure the network interface and air conditioner
settings before it is connected to a network.
Windows is a registered trademark of Microsoft Corporation in the United States and/or other countries.
When a Commboard is installed in a Hoffman air conditioner, it can communicate with an external
computer or PLC using the SNMP, EtherNet/IP, Modbus TCP, and PROFINET protocols.
