FWC Fresh Water Controllers
The controllers of the FWC series enable fast and precise regulation of the tap temperature in central fresh water stations. The heat from a storage is controlled and transferred to a heat exchanger via a pump or valve using the continuous flow principle, thus providing precisely tempered and legionella-free domestic hot water at the taps.
SFWC
Fresh water controllers for small fresh water stations with speed-controlled high-efficiency pump.
MFWC
Controller for fresh water stations with speed-controlled primary pump and additional functions like control of circulation pump.
LFWC
Controller for fresh water stations with speed-controlled high-efficiency pump + additional functions.
OEM service: We’ll happily contribute with our 10+ years experience in developing fresh water systems, and support you in the initial adjustment of all control parameters to your stations – for quick and precise tapping temperatures in every common tapping situations.
Advantages of SOREL fresh water controllers
Full text menu
Clearly understandable, context-sensitive help texts explain each setting value.
Setup Wizard
Guides step by step through all necessary settings for quick and easy commissioning.
Graphic display
Animated visualisation of the system, clear characteristic curves and energy statistics.
Modular principle
The systems can be flexibly expanded by activating additional functions using free relays.
Multilingual
Various menu languages can be freely selected for clear communication.
PC-Simulation
Free Windows software simplifies training, functional testing and technical support.
Networkable
Controllers can be networked via CAN bus or connected to the Internet.
Cascade function
Connection of additional fresh water stations via digital bus in case of high tapping volume. An additional master / cascade controller is not required.

The setup wizard guides you quickly through the settings to be made in a logical sequence. This prevents incorrect settings and facilitates parameterisation.
The current measured values and operating states are displayed in an animated overview. In addition, important functions are shown as symbols in the display.
For each day of the week, 3 operating times can be set for the heating circuit and adopted for other days.
The menu offers query, evaluation and setting options.
The self-explanatory user guidance enables simple parameterisation, which is supported by corresponding explanations.
Security checks and menu blockers protect against unintentional adjustments.
Functional control and long-term monitoring of the system is made possible by recording and evaluating the data.
The menu locks protect against unintentional adjustments.
The menu can be switched between various languages.
