Heat exchanger temperature sensors
There are two contact temperature sensors per heat exchanger. One temperature sensor is located on the
inlet supply piping and one temperature sensor is located on the outlet return piping. These sensors measure
water temperature and report data to the ECS.
Facility connections to ECS
You can connect your facility to the ECS using the RJ45 in the demarcation box or cables that are hard-wired
through the connection portals on the cargo end of the HP POD 20c. The system uses Modbus TCP/IP for
communication.
Connecting to the ECS
To connect the network to the ECS control panel, route an Ethernet cable to the appropriate RJ45 connector
inside of the HP POD 20c demarcation box.
