Areas of application
- Apartment building
The VARIO fresh-flat home station is a completely new generation in modular design. Based on a highly flexible plug-in system, individual modules can be combined hydraulically and functionally precisely for the respective application.
The heart of the system is the TWW base module with the VarCon211 electronic controller and the new, innovative „OptiStep“ control valve.
The OptiStep valve combines a high-quality stepper motor with a pressure-independent valve for particularly precise and stable
DHW heating via the plate heat exchanger using the flow-through principle (fresh water heater).
The home station supplies an apartment with hot and cold domestic hot water. In addition to the room heating supply, the station is used as required.
extended.
Thanks to the modular design, ball valve manifolds, for example, can be installed at the start of the screed and the complete station can be installed later in just a few simple steps.
be added.
Home stations can be networked via Modbus
Facilitates station configuration, media and temperature flow control, remote diagnostics
Stable heating and hot water temperatures
Ultrasonic flow measurements in the domestic hot water outlet and in the primary supply on the heating side
Precise domestic hot water preparation
Even with very low dispensing volumes thanks to the combination of OptiStep and pressure-independent valve
