oventrop Regucor WHS Einbau- Und Betriebsanleitung Seite 35

Heating circuit station: The "Regucor WHS" is supplied with a variable temperature circuit product assembly. It can be extended by an
additional variable temperature circuit (Oventrop item no. 1383570). A nominal flow temperature for each heating circuit is calculated by
the controller on the basis of the average outside temperature (S9) and the selected heating curve. If the measured flow temperature (S8)
deviates from the calculated nominal flow temperature, the actuator of the mixing valve (R5 or R6) is activated and the flow temperature is
adapted accordingly.

Fresh water station: Hygienic hot water preparation on the flow principle is carried out by the hydraulically controlled product assembly
– the control range can be set between 40°C and 70°C via a thermostatic temperature controller.
The flow switch (FW7) is connected to the controller "Regtronic RS-B" and is closed during draw off and circulation operation. If the flow
switch (FW7) is closed, the circulation pump Wilo-Yonos PARA RS15/7 delivers heat from a buffer storage cylinder to the heat exchanger.
An additional potable water circulation pump can be connected to the controller "Regtronic RS-B" via the extension set (Oventrop item no.
1381049). Five models are available for the control logic:
1. Thermal
3. Thermal + timer
5. Demand + timer
The circulation function is detailed in chapter 9 of the controller installation and operating instructions.

Post-heating/hot water preparation: Post-heating of the storage cylinder for the heating circuit and hot water preparation for the energy
storage centre is controlled by the controller "Regtronic RS-B". Important: The specifications in the installation manual of the heat ge-
nerator must be observed
The allocated demand relay (R14) is switched on if the temperature in the centre of the storage cylinder below the separation sheet
(heating circuit operation) or in the upper section of the storage cylinder above the separation sheet (potable water part in stand-by
motion) drops below a minimum temperature. The potable water part in stand-by motion and the storage cylinder section for the heating
circuits are loaded separately via the conversion valves at R13. As post-heating of the heating circuits depends on the calculated nominal
flow temperature, an efficient post-heating and loading of the respective section of the storage cylinder are guaranteed. The controller only
requests the heat which is actually required from the heat generator.

Note regarding switching between the storage cylinder sections: The conversion valves for zone loading can be activated via the se-
lection function "Hot water preparation" by selecting "Loading pump" (software version 1.09) or "Pump/valve" (software version 1.10).

The three-way valves "Tri-D TR" (Oventrop item no. 1130206) and "Tri-M TR" (Oventrop item no. 1131706) with the electromotive 2 point
actuator (Oventrop item no. 1012710) can be used for the switching operation.
An angle pattern adapter (Oventrop item no. 1641451) is additionally required for mounting the actuator onto the three-way valve "Tri-D
TR" – the installation instructions of the actuator must be observed.
