B.3. - About the controller
The Fresh water controller SFWC facilitates ef cient use and function control through of
your fresh water system. Tap water temperature is regulated fast and precise. The device is
impressive most of all for its functionality and simple, almost self-explanatory operation. For
each step in the input process the individual entry keys are assigned to appropriate func-
tions and explained. The controller menu contains headwords for the measured values and
settings, as well as help texts or clearly-structured graphics.
Important characteristics of the SFWC:
- Depiction of graphics and texts in a lighted display
- Simple viewing of the current measurement values
- Analysis and monitoring of the system by means of statistical graphics,etc.
- Extensive setting menus with explanations
- Menu block can be activated to prevent unintentional setting changes
- Resetting to previously selected values or factory settings
B.4. - Scope of supply:
- Fresh water controller SFWC
- replacement fuse 2A slow-blow
- Installation and operating instructions SFWC
Optionally contained depending on design/order:
- Pt1000 temperature sensor and Vortex Flow Sensor
B.5. - Disposal and pollutants
The unit conforms to the European RoHS directive 2011/65/EU for the restriction of the use
of certain hazardous substances in electrical and electronic equipment.
Caution
The unit must not under any circumstances be disposed of with ordinary
household refuse. Dispose of the unit only at appropriate collection points or
ship it back to the seller or manufacturer.

Description of controller
The following illustrations should be viewed only as schematic diagrams
showing the respective hydraulic systems, and do not claim to be complete.
The controller does not replace safety devices under any circumstances.
Depending on the speci c application, additional system components and
safety components may be mandatory, such as check valves, non-return
valves, safety temperature limiters, scalding protectors, etc., and must there-
fore be provided.

C.1 Wall installation
1.Unscrew cover screw completely
2.Carefully pull upper part of housing from
lower part.
3.Set upper part of housing aside, being
sure not to touch the electronics when
doing so.
4. Hold the lower part of the housing
(C.1.2) up to the selected position and
mark the 2 mounting holes. Make sure
that the wall surface is as even as possi-
ble so that the housing does not become
distorted when it is screwed on.
5. Using a drill and size 6 bit, drill 2 holes
at the points marked on the wall and push
in the plugs. Also possible is the installati-
on with 4 drill holes.
6. Insert the upper screw and screw it in
slightly.
7. Fit the upper part of the housing and
insert the other screws.
8. Align the housing and tighten the
screws.
Caution
Install the controller only in dry areas and under the ambient conditions
described under 2.1 “Speci cations”. Carry out the following steps:

C.2 Electrical connection
Before working on the unit, switch off the power supply and secure
it against being switched on again! Check for the absence of power!
Electrical connections may only be made by a specialist and in
compliance with the applicable regulations.
Do not use the controller if the housing shows visible damage.
Low-voltage cables such as temperature sensor cables must be routed
separately from mains voltage cables. Feed temperature sensor cables
only into the left-hand side of the unit, and mains voltage cables only
into the right-hand side.
The customer must provide an all-pole disconnecting device, e.g. a
heating emergency switch.
The cables being connected to the unit must not be stripped by more
than 55mm, and the cable jacket must reach into the housing just to the
other side of the strain relief.
We recommend the use of exible cables to ease the installation in the
clamp room.
Caution
1.Select necessary program/hydraulics
(see section D)
2. Strip cables by 55mm max., insert, t
the strain relief devices, strip the last
9-10 mm of the wires. (Fig. C.2.1)
3.Open controller as described under g.
C.1.1, insert cables and install strain
reliefs
4.Install PE terminal block (see g. 2.1.a).

Installation
5. Connect the female connector block ‘s
clamp connections as described in the
terminal connection plans. When using
stranded cables, use a small screw dri-
ver and push the orange buttons while
inserting (see g. C.2.1.c). When using
solid cable or end splice, just push the
cables in (see g. C.2.1.d).
6. Plug Female connectors into onboard
headers.
7. Hinge the upper part of the casing on
the top of the lower part and close the
casing gently.
8. Fasten with screw.
9. Switch on mains voltage and place
controller in operation.

To remove the female connector block
from the header, carefully bend the latch
on the header.
Caution: The latch breaks easily.
