Steffes 9180 - Manual (Page 8)

loaD ManaGeMent control
The system is designed to operate under one of many load management control strategies.
1. BaCNet Control
Steffes commercial heating furnaces are available with a BACNet control op-
tion (Order Item #1301015). This device is easily integrated into most building
automation systems to provide building managers full control and visibility of the
heating system’s operation. BACNet allows the following functions to be moni-
tored with simple, twisted pair communication:
Real time system monitoring •
Full thermostat control •
Monitoring of heat storage levels in the brick and all system temperatures •
Remote configuration, testing and adjustment •
Service requirement alerts •
2. 4-20 Milliamp Control (1-5 volt dC)
System receives a signal from an external load control device such as a building load management
system. This external signal dictates the maximum amount of energy which can be consumed dur-
ing a preset time interval.
3. Pulse Monitoring
a) System monitors pulse outputs from the power company's electric
meter. Program parameters such as desired maximum building
kW and pulse ratios for the metering system being used are pro-
grammed into the ThermElect system. The system then charges
proportionally when demand free power is available. This keeps
the total building kW usage at or below the desired level.
b) External load management control modules (Order Item
#1908140) are available when using pulse monitoring load con-
trol. Each module has eight (8) zones which can be controlled. The
system must be configured to recognize the number of load man-
agement modules installed (maximum of two per system).
4. Conventional Peak Control
The ThermElect Hydronic system responds to heat calls during the on-peak and off-peak periods;
however, only consumes energy (energize heating elements) during the off-peak periods. The
ThermElect Hydronic system is controlled by an external control device such as a meter, time clock
module, or BACNet control.
