Installation Guide
5.8 Electrification
Since the internal electrical connections are factory made it is not
mandatory to use an electrician to connect the substation. The
contact plug is the main electrical switch in the substation.
The outdoor temperature sensor is to be installed on the north
side of the property at app. 3 m height where the outdoor tem-
perature can be measured. There should be no ventilation window
at the close proximity to the measuring point. The other end of the
outdoor temperature sensor cable is to be connected into the con-
trol box. When connecting outdoor temperature sensor make
sure to remove the substation contact plug.
In case the length of the outdoor temperature sensor cable is not
long enough for your property, it is remmendable to change the
whole cable. This way extra joints are avoided. The minimum area
2
for the cable is 0.4 mm and the maximum length is 125 m. If you
choose to use the extra joint inspite of recommendation, protect
the jointing sleeve with the shrink cable.
Stick the contact plug into the wall socket fitted with a 10A/220V
fuse.
Wait for 10 s, turn the circulation pumps P1 (DHW) and P2 (HE) on
by pressing the operating switches.

Controller settings

Description
The ECL Comfort electronic weather compensated temperature
controllers are for use in district heating, central heating and cool-
ing systems.
Energy savings are facilitated by weather compensation, adjust-
ment of temperature according to schedule, optimization as well
as limitation of return temperature, flow and power. Functionalities
such as data logging and alarm functions are implemented in the
controller.
Property specific controller settings
There are some property related settings which are to be done
before starting up the substation. A complete controller instruc-
tion is included and the most important details are also enclosed
in this Installation Guide.
