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.
