How to use this guide
This guide is divided into two parts:
• User’s Guide: Yellow sections 1-7
• Installer's Guide: Grey sections 10 and onwards
The application F18 is very flexible. These are the basic principles:
The domestic hot water (DHW) storage tank is equipped with
three temperature sensors: S3, S4 and S5.
S3 is used for switch on and switch off of the electric heater in
connection with an extra energy source. The desired DHW storage
tank temperature sensor (S3) has two settings, one for reduced
temperature and one for comfort temperature which is controlled
according to the schedule in circuit I.
The DHW storage tank temperature sensor S4 decides the switch
on of the fuel cell energy supply and sensor S5 determines when
to switch it off.
S1 and S2 ensure that the temperature to and from the fuel cell
energy supply is kept under the acceptable values. If these are
exceeded, the fuel cell signal is overruled, FC and the alarm code
can be read.
A DHW tapping is detected by means of a flow switch, FS. The
DHW circulation pumps P2 and P3 stop, and the primary pump
P1 starts. When the DHW tapping stops, P1 will stop, and P2 and
P3 will be controlled according to the schedules in circuit I and II,
respectively. The readout of the DHW temperature sensor S6 can
be used when adjusting the DHW temperature.

Disposal instruction:
This product should be dismantled and its
components sorted, if possible, in various
groups before recycling or disposal.
Always follow the local disposal regulations.

Installation
Installation
For easy access, you should mount the ECL Comfort
controller near the system. Select one of the three
following methods:
• Mounting on a wall
• Mounting on a DIN rail
• Mounting in a panel
Screws and rawlplugs are not supplied.
Mounting on a wall
Socket for mounting on wall: Order code No. 087B1149.
Mount the terminal box on a wall with a smooth surface.
Establish the electrical connections and position the
controller in the box. Secure the controller with the fixing
screw.
Mounting on a DIN rail
Mounting kit: Order code No. 087B1145.
A mounting kit is necessary to mount the box with the
controller on a DIN rail.
Mounting in a panel
Connector set: Order code No. 087B1148.
The panel plate thickness must not exceed 3 mm.
Prepare a cut-out with the dimensions 93 x 139 mm. Pull o
the right side of the lid by means of a screwdriver.
Insert the controller into the panel cut-out and fix it with the
two locks which are placed diagonally in two corners of the
controller.

How to insert your ECL Card the first time
After the power has been switched on, open the lid on the
front side of the controller.
Place the ECL Card with the yellow side facing you. This
enables the controller to read the ECL Card data. The
controller immediately starts to copy the application type and
factory settings from the ECL Card. After copying, the display
will show you the application type. After approx. 10 sec. the
display will change to display line C.

Understanding the ECL Card
The ECL Card contains factory settings for a standard
system. If the actual system differs from the standard
system, the controller must be adjusted accordingly. After
the adjustment, the new settings should be stored on the
ECL Card.
For ECL Card copying and daily use including adjustment
of temperatures and schedules, insert the ECL Card with
the yellow side facing you.
For system set-up adjustments, the grey side of the ECL
Card - the installer’s side - must be facing you.
As a main rule, the ECL Card should always remain in the
controller during service, maintenance and setting.
If the card is removed or left in the controller with the grey
side facing you, please note that:
• After approx. 25 min.:
- The controller cannot be operated.
- The controller reverts to display C (section 1).
• The ECL Card must not be exposed to direct heat or
sunshine.
If several controllers are installed in the system you can
write a title on the ECL Card with a permanent ink pen.
Do not remove the ECL Card while copying. The data on the
ECL Card can be damaged!
When you store your personal settings on your ECL Card, the
factory settings will be overridden.
