ctrical connector
5.2 Connecting the cable
- Connection is performed according to the installation
scheme in the image number 7.
- The neutral (zero) line is connected to the corresponding
regular clamp (N) located on the right side of the fuse set with
the voltage trigger.
The regular clamp of zero line is blue.
- Instead of the conventional regular clamp for connecting the
power cable, there are three-pole automatic fuses in the
boiler, into which the power cable is introduced.
The three-pole
set of automatic fuses has been upgraded with a remote voltage trigger
so that a safety circuit is achieved which, in addition to short-term
electricity protection, responds to thermal overload (the signal from the
safety thermostat activates the voltage trigger) and at the same time
interrupts the supply of all three phases into the device.
- The phase conductors are connected to a three-pole fuse (L1, L2,
L3)
ATTENTION! When connecting the phase
conductors, be sure to tighten the screws in the
automatic fuses in order to achieve the best
possible connection between the cable and the
clamp. Pr
ili
kom povezivanja faznih
- Connect the line for grounding to the regular clamp which is marked
with the sign for grounding. The regular clamp of the line for
grounding of the device is green and yellow.
NOTE: The remote voltage trigger is factory-
connected within the safety set of the device
and NO cable is connected to it subsequently.
NOTE:
The room thermostat is connected to the
additional regular clamps (5V, IN) and it interrupts
the voltage of 5V DC which comes from the
processor panel of the boiler.
- It is necessary to use room thermostats with
independent power supply eg. Battery, or Centrometal
room thermostat EST113 R5
DANGER!
If a good connection between the cable
and the clamp is not achieved there may
come to uncontrolled heating of fuses and
their failure.
-
This boiler is not intended to operate without
a room thermostat or an external control unit
Image number 7 Scheme of connection of power cable
- When introducing a power cable into the boiler, through
any selected set of entries for introduction, carefully pull
through the cable to the three-pole automatic fuses to
avoid damaging the cable sets inside the device.
NOTE! The connection of this device must
be carried out by a person that is qualified
to perform this kind of work.
- When you are finished with the connection of the
power cable and room thermostat, it is necessary to lift
the fuse set together with the remote voltage trigger
before closing the device, that is, before installing the
front cover, in order to ensure the power supply to the
boiler.

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.

- 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
.

7.2.2 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!: I
f 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.

Setting the operating regime
Description of the SAFETY regime
Checked everything works according to the rules given for the specific
mode defined by the combination of the selected symbols in
the first two items of the menu. The program protects the
heating system from low temperatures by not allowing the
operation of the boiler on temperature of 3˚C or below (which
is measured by the sensor in the boiler) because there is a
risk that the installation is frozen.
Bin a system filled with a mixture of antifreeze and thus protected
from freezing. Everything works according to the rules given
for the specific operating regime which is defined by the
combination of selected symbols in the first two items of the
menu, but a part of the program that blocks the operation of
the boiler at a temperature of 3 °C or lower is switched off. In
other words, operation of the boiler is allowed regardless of
the possible low temperatures in the boiler. Also, there is no
need to warn about approaching to the lower limit of the
allowed temperature, as well as about the low temperature
errors.
Snowflake activated freezing protection regime. This regime is designed
to protect against freezing of the system in a shorter period
(10 days), e.g. during winter, when there is no need for
heating in the house (apartment), but due to low outdoor
temperatures. There is a possibility that the system freezes if
the heating is switched off and the system is not filled with
antifreeze. The pump operates non-stop in this regime,
maintaining the temperature of the system from 7-10˚C by
using 1/3 of the nominal power. The relay of the boiler is
switched off for 20 minutes and switched on again for 10
minutes to protect the heat exchanger in the boiler. When this
regime is selected, the first two items of the menu are
automatically de-checked, and no setting can be made until the
safety mode changes and one of the other two signs (operating
regimes) is selected instead of the snowflake.

lower than the set one, which is reduced by 3˚C, the relay of the boiler is
switched on (the motor valve is switched, which directs the water from the
boiler to the heat exchanger in the boiler), 'b' appears on the display, and if
necessary, relays of the heater switch on or off depending on the temperature.
- when symbol √ is in the safety mode, operation of the boiler is blocked on the

Tk - Current temperature of the boiler in any regime
SANITARY WATER PREPARATION REGIME – BOILER REGIME
Tbz - The set temperature of the boiler to which the water in it should be warmed.
In this regime, the temperature of the boiler to which it needs to heat is calculated as:Tkz = Tbz + 15 C
Tb - Current temperature of the boiler. PUMP WORKS UNTIL Tb = Tbz

THE SETTING MODE IS ENTERED BY SHORT PRESSING OF THE ‘SET’ BUTTON IN ANY REGIME:
The display shows 'G', the set temperature of heating starts to flash and it can be set in the range of 10 - 80˚C. When it is set by pressing 'OK', it switches to the setting of the following parameter: the set power of heating flashes - after the setting (if
preparation of sanitary water is not activated), if the 'OK' button is pressed, the set heating temperature flashes and thus in
circle. To remember the changes that are made, that is, the new set values and to exit from the setting, the 'SET' button must
be pressed. If the 'SET' button is not pressed within 15 seconds from the last pressing of some of the other buttons, the
processor exits the setting mode and continues to work according to the “old” set values of power and temperature.
The setting is continued after setting the temperature and the power of the heating, if the preparation of sanitary water is
activated as well:
- now, instead of the symbol of radiator, the symbol of boiler appears (overview 'B'). The presented current temperature is the
temperature of the boiler, and the set temperature of the boiler that can be set in the range of 10 - 70˚C starts to flash and it is
taken (increased by 15˚C max. 80˚C) as the temperature to which the boiler is heated while in the sanitary water preparation
regime. If the ‘OK’ button is pressed after setting this temperature, the set power of the boiler for the preparation of the sanitary
water begins to flash, and it should be set taking into account the volume of the boiler, the power of the heat exchanger and the
nominal power of the boiler, that is, choose the optimum power for preparation of hot water in the boiler. To remember the
changes that are made, that is, the new set values and to exit from the setting, the 'SET' button must be pressed. If the 'SET'
button is not pressed within 15 seconds from the last pressing of some of the other buttons, the processor exits the setting mode
and continues to work according to the “old” set values of power and temperature.

Timer in sanitary water preparation regime
Function of the timer in sanitary water preparation regime
A timer appears on the display next to the symbol of boiler in the setting
mode when the function of sanitary water preparation is enabled. Format
of the timer is 00:00 - 00:00 (24h marking time).
It appears only when the function is CHECKED.
The devices comes as factory-set at 00:00 - 00.00 which means that the
timer allows the preparation of sanitary water throughout the day. If two
times are set, for example: 22:50 - 22:50, the preparation of sanitary
water is still possible throughout the day.
This function is introduced in order to connect the boiler to another
heating system, for example: solar or to solid fuel boiler. It is good then to
set up the preparation of sanitary water in a certain period of time when
there is no sun or when the solid fuel boiler is not charged.
The image shows an example of setting the function of the preparation of
sanitary water for a period of time from 20:00 to 04:00. There is no energy
of the sun in this period, so it is necessary to prepare sanitary water for
use in the evening or in the morning hours.
This setting also allows the preparation of sanitary water in hours of less
expensive electricity.
Setting
When the sanitary water preparation regime is enabled, a timer appears on the display. We go through the setting parameters
by pressing the OK button. Time will start to flash in the following order:
00:00 - 00:00 – hours of switching on are set (for example 20)
20:00 - 00:00 - minutes of switching on are set (for example 30)
20:30 - 00:00 - hours of switching off are set (for example 04)
20:30 - 04:00 - minutes of switching off are set (for example 30)
Means that we set the time to 20:30 - 04:30
Every setting in any regime is confirmed by pressing the SET button.

Note:
when the set power can not be divided into 3 groups, it is divided into 2 groups, (for example, with a boiler with a nominal power
of 6kW and set 4kW, it can only be divided as 2 + 2kW) or, if this is not possible as well, then the complete set power switched
on and off in one degree (for example, with a boiler of nominal power 6kW and set 2kW - it can not be divided into 2 or 3
groups).

Note:
The heating group can consist of one heater, or 2, or 3 heaters, depending on the power of the boiler. Also, the heating groups
do not always consist of the same heaters, but are formed from heaters which, at the time of switching on/off, selected by the
microcontroller based on the criteria for the minimum operating time of a particular heater, while respecting the symmetric load
according to phases.
