Equipment funtioning EQUIPMENT FUNTIONING Feeder system The fuel is transported from the fuel storeroom by means of a feeder screw with flat spring stirrer for burnback protection devices. It then passes through the drop shaft and the burnback protection device. The burnback protection device is driven by a spring-loaded servo-motor.

Operating conditions Control phase OPERATING In this phase the boiler is modulated between CONDITIONS nominal load and partial load. When the partial load stage generates too much energy, i.e. the target boiler temperature + regulation hysteresis Heating off are exceeded and are then changed to the ready In this condition the equipment is switched off, i.e.
Page 14
Operating conditions Frost protection When the equipment goes into frost protection then the return flow bypass pump is switched on provided that the equipment is in “HEATING OFF” or “BURNER STOP” condition. Otherwise the equipment is started up and started up to a minimum temperature of 65°C.
Temperature manager TEMPERATURE MANAGER The control of the heat demands of the individual modules (=heating circuits) happens with a so-called temperature manager. To understand the operation of the temperature manager the scheme which is illustrated in Figure 6.1 is used. It can be seen that a module has inputs and outputs. The module gives a so- called temperature demand to his “heat supplier”.

Modbus is an application protocol for the exchange of messages between intelligent Modbus controllers in the building management system. The Modbus protocol “TCP” is used in the HERZ control. This protocol transmits the encoded data via LAN cable. Modbus ensures that connected controllers in the building management system become the transmitted data from the boiler, so that they can continue processing.
