SYNERGYR

Central Unit

OZW30

Collects billing data from the apartments. Generates an image of each apart-

ment's heat consumption and makes it available for readout. Acts on room tem-

perature control in the apartments. Has an impact on heat generation depending

on the apartments' demand for heat. Acquires operating state signals, actual

values and faults. Passes alarms to an operator station.

Use

The OZW30 central unit is a component of the SYNERGYR

control and billing system.

The following system functions are only possible when using the central unit:

• Central readout and storage of the most important consumption data from the indi-

vidual apartments

• Fault indication and logging

• Straightforward readout with the help of the memory card

• Acting on heat generation

For the field of use of the SYNERGYR

system, refer to Data Sheets N2800 to N2803

(System Overview).

Switching load compensation With switching load compensation, the heating group controller is switched from normal temperature to setback temperature, and vice versa. The change to setback operation takes place: • When the apartments do not call for heat, e.g.

Mechanical design The central unit consists of a base, with the power supply section and the connection terminals, and hinged operating section. Base Operating section The hinged operating section also serves as a cover. Its front carries the display, the buttons and the operating cards. All operating elements are located beneath a hinged transparent cover. It can be locked with a key while the operating section is secured to the base by means of a lead-sealable screw.

• The information; it is assigned to the selected address and the designation; parameters are changed via 3 buttons • The unit (kWh, l/h, °C, etc.) • 4 text symbols: − DATA: Loading data − CARD: Memory card inserted and accepted − ERROR: Fault status message − BAT: Battery exhausted (reserve and memory card) Another button is used to store consumption data on the memory card. During operation, the display shows the time of day or – if present – alarms.
