Overview of handling elements
The boiler can work in four (4) regimes.
1 Heating,
2 Preparation of sanitary water,
3 Heating and sanitary water,

We will briefly introduce you to the most important
characteristics of the boiler Compact ePlus
- Electric boiler Compact ePlus contains all elements of
boiler substations ie. small boiler rooms.
- Unlike previously known models, this model has many
advanced functions that not only make it easier to work
with the device, but also provide a longer life and safer
operation of the device.
- The temperature sensors and sensors of the hydraulic
pressure of the water in the installation monitor changes in
the system and send information to the processor that
processes them and controls the boiler based on them.
- Communication of users and service technicians (installers) with
the device is facilitated and improved through a display showing all
the essential parameters of the device and the system itself.

Power and steps
of adjusting the power
- The setup is facilitated and performed by four buttons
located just below the display.
- The processor takes care of:
- Even load of phases no matter of the power
on which is set the boiler.
- Even load of output relays and heaters.
-
If necessary, the relays and heaters that have been
switched on for a long time are switched off, and relays
and heaters that were inactive switche on instead.
- In this way, the electrical network is symmetrically loaded,
and all elements of the boiler work equally, thus achieving a
longer lifetime of exploitation of the device.
Operating temperature
-
is set in steps of/from 1 °C
-
The operating temperature range ranges from 10 °C to 80 °C

is carried out periodically with a 3-second intervals with
division of power in three (3) groups which are
temperaturely-
shifted by 3 °C.

Basic settings
- It is necessary to set the operating pressure to 1.2 bar (+
0.4) for normal operation of the device when filling and
discharging air from the heating system.
- If the operating pressure is less than 0.8 bar, a warning will
appear on the display (see table 3 Warning signs) and if
the operating pressure continues to fall and drop below 0.4
bar, the boiler will be switched off with the error information
on the display.
- If the operating pressure is greater than 2.2 bar, a
warning will appear on the display, and if it exceeds 2.6
bar, the boiler will be switched off with the error
information on the display.
ATTENTION!:
If the operating pressure continues
to increase, the mechanical safety valve will open at
3 bar and release the part of the water from the
boiler, until the pressure drops to the allowed value.
- The circulation pump has the choice of three (3)
powers of 40W, 59W and 84W.
