2.3 ELECTRONIC CONTROL SYSTEM (ECS) INSTALLATION
As previously mentioned, the Control Box and all other Electronic Control System (ECS)
components are installed on the Packaged Water Heater prior to shipment from the factory.
Therefore, ECS installation basically consists of connecting external AC power to the System
and providing the necessary power and control signal connections to the Control Valve Type
CXT-E. However, if your ECS was ordered with the Modbus Communication option, several
additional signal lead connections will need to be made inside the Control Box. These signal
leads will permit the ECS to be controlled by an external Energy Management System (EMS),
Building Automation System (BAS), or Computer.
NOTE:
Following installation, a lock (Not Supplied) can be installed on the
front door of the Control Box, if desired, to prevent unauthorized
access to ECS settings.
