1.2 ELECTRONIC CONTROL SYSTEM/SMARTPLATE (ECS/SP)

Identical Electronic Control Systems are used on all SmartPlate Models. This system,

commonly referred to as the ECS/SP, contains a Control Box Assembly which includes all of the

electronic circuitry for the ECS/SP. In addition, the ECS/SP includes several sensors and safety

devices which provide temperature and flow control information to the Control Box circuitry. The

Control Box and the additional devices included in the ECS are shown in Figure 1-2. The

additional devices included in the ECS/SP include:

 Feed-Forward (Mixed Water) Temperature Sensor (Type J Thermocouple)

 DHW Outlet Dual Temperature Sensors (Type J Thermocouples)

 Boiler Water Inlet/Outlet Temperature Sensors (Type J Thermocouples)

 Over-Temperature Alarm (With Safety Shutdown)

If desired, the Electronic Control System (ECS/SP) can be ordered with a Modbus

Communication Option. This option permits the ECS/SP to be externally controlled by an

Energy Management System (EMS), Building Automation System (BAS), or Computer supplied

by other manufacturers.

The ECS/SP assemblies and components are described in the following subordinate

paragraphs.
