CONFORMITY/ MARKING
This product complies with the requirements of the follo-
wing European directives and standards:
- 73/23/EEC, Low Voltage Directive
Corresponding standard: EN 60.335.1.
- 89.336/EEC, Electromagnetic Compatibility Directive
Corresponding standards: EN 50.081.1 ; EN 50.082.1 ;
EN 55.014.

3
The boiler must be connected by a qualified
professional. Strict compliance with these
usage, electrical connection and start up
instructions is a precondition for the correct
operation of the boiler.
The E control panel is used on the following
De Dietrich boilers:
- GT 120 A and GT 1200 A.
1. GENERAL
1.1 Presentation
The E control panel with an Easymatic regulator to
be fixed to the wall or integrated into the boiler
control panel can be used for:
- automatic operation of heating when the ambient
temperature has been reached
- control of heating as a function of the outside tempe-
rature.
- regulation and programing of domestic hot water pro-
duction (if it is present) with or without priority
- providing a frost free room temperature if the home is
empty. The duration of this period may be programed
up to 99 days.
The basic delivery of the E control panel comprises
- 1 E control panel
- 1 Easymatic regulator with support to be installed in
the chosen room or to be included in the control panel
- 1 boiler sensor measuring the water temperature in
the boiler
- 1 external sensor
Options
The following option can be ordered:
- domestic hot water sensor (package FM 45).
1.3 Technical characteristics
The E control panel can be used to program and regu-
late the room temperature as a function of the outside
temperature by controlling the burner. The boiler
thermostat must be set to a sufficiently high tempera-
ture for automatic regulation to operate correctly (set-
ting between mark 8 and 9).The safety thermostat with
manual reset (adjusted to 110°C/230°F) maintains
operating safety.
In the case of domestic hot water (d.h.w.) production,
domestic hot water is regulated by the regulator acting
on the load pump giving priority to heating of domestic
hot water.
When a request is made for heating domestic hot
water, the domestic hot water priority stops the burner
and the d.h.w. load pump and stops the heating pump.
Under summer conditions, the boiler is not kept hot
between two domestic hot water loads. The domestic
hot water temperature is measured by the d.h.w.
sensor.
The regulator includes the possibility of a "antilegio-
nellosis" protection.

tronic regulation:
- the burner is put into forced operation
- the boiler temperature is no longer limited by the
regulation
- the boiler thermostat G is used to regulate the boiler
temperature
- the heating pump and the domestic hot water load
pump (if there is a calorifier) are started - the display
is off.
This operating mode is achieved using the Telcom 1
voice remote monitoring module option.
The display shown in the figure appears during this
operating mode.
Heating is automatically cut off during the summer
when the outside temperature is higher than the ”com-
fort” temperature setting for 2 hours.
The display remains identical, but the pump is perma-
nently off. The symbol is no longer displayed.
Heating is started again when the outside temperatu-
re drops below the ”comfort” temperature for 2 hours.

there is a calorifier) can be adjusted at any time
using key 1(see chapter 4).
●Select the operating mode using keys 5, 6and 7
(see chapter 2).
●Customize the heating program and the d.h.w.program
as you wish if you have domestic hot water production
(see chapter 6).
●Check that the switch Dis in the AUTO position.
●Check that the thermostat Gis in the AUTO position

●Check that the safety thermostat Bis properly set.
Unscrew the safety thermostat cap and press the
reset button.
●Put the On/Off switch Cinto the On position.
Note
For production of domestic hot water (d.h.w. sensor
connected), an automatic bleed sequence is carried
out of the calorifier exchanger for one minute by inter-
mittent operation of the domestic hot water load pump
and the heating pump, before changing to automatic
operation mode.
This bleed sequence is only activated if the calorifier
temperature is greater than 25°C / 77°F.

Electrical connections shall be carried out
by a qualified professional only.
The electrical wiring has been carefully
checked in the factory and the internal
connections of the control panel must not
be modified in any event.
Electrical connections shall be made respecting the
information given on the electrical diagrams delivered
with the equipment and the directives given in the
instructions.
The electrical connection must comply with applicable
standards and regulations in force. The equipment
must be powered by a circuit with an omni-pole switch
with an opening distance greater than 3 mm.
ELECTRICAL CONNECTIONS
All connections are made on the terminal blocks
provided for this purpose at the back of the boiler
control panel.
The connecting cables may be brought inside the boi-
ler through the cut-outs provided in the boiler back
panel, which may be used along with purchased cable
channels.
Fasten the cables to the rear plate of the control panel by
means of the cable clamps (cable clamps supplied in a
separate pack) after mounting them on the plate.
IMPORTANT: The maximum current that can be
switched per output is 2 A cos. ϕ =
0,7 (= 450 W inrush
current less than 16 A).
Sensor cables must be separated from
cables in 120V circuits.
- In the boiler: use two cable glands on each side of
the boiler for this purpose.
- Outside the boiler: use two cable channels or
cableways with a minimum distance of 10 cm
[4.0 inches] between them.
