ATTACK, s.r.o

1. General information

1.1 Description and use

The wall hung electric boiler ELECTRA EXCELLENT is
convenient for heating in heating systems with forced
circle and for heating of service utility water (sanitary
water).
The heating of heating water takes place in a boiler drum
by means of one (EXCELLENT 08), two (EXCELLENT 15)
or three (EXCELLENT 24) heaters of a power output of
4,5 kW, 6 kW or 7,5 kW. Each heater consists of three
heating rods of a power output of 1,5 kW, 2 kW or 2,5 kW
each. Heating operation is controlled by control unit with
PID regulation. PID regulation assures high efficient
operation due to minimalizing of heating water
temperature overshoots over temperature setting. This
regulation saves also your energy consumption. The
boiler could be regulated by the room thermostat and it
also able to heat sanitary water in an independent storage
water tank connected through with 3-ways motoric valve.

and rules ČSN EN and IEC. The safety of the boiler, energy
saving and sound was important matter during the boiler
designing.

1.7.2 Principle of boiler operation

The insulated boiler body with volume 10,6 l is a reservoir
where water is heated by electric heating elements
according to the boiler type, by one (08 kW), two (15 kW)
or three (24 kW). Depending on the actual heat
requirement, individual heating rods are connected, each
of them having a power output of 1,5 kW for Comfort 05
and Comfort 09 (1 heating rod = 1,5 kW, 6 heating rods 9
kW), a power output of 2 kW for Comfort 06, Comfort 12
and Comfort 18 (1 heating rod 2 kW, 9 heating rods 18 kW)
or a power output of 2,5 kW for EXCELLENT 15 and
Comfort 24 (1 heating rod = 2,5 kW, 9 heating rods 22,5
kW). Circulation of water is through the pump. Safety of
boiler operation is monitoring by several independent
sensors. Whole heating process and pump operation is
controlled by the control unit with display and push touch
control buttons. The button 0/1 is for switching off the
boiler out of operation.

1.7.3 Control unit and control board

Control unit has several functions which assure basic
characteristics, mainly:

safety functions assure protection against the of health



and property

user's functions functions set by the user



operation functions internal functions of control unit



import for sound operation of the boiler, but un-get-at­able for the user

Control unit could be in below mentioned modifications:

basic only for heating = control unit + mode relay



for heating and heating of sanitary water = control unit



+ mode relay + mode TUV (sanitary water)
for heating with GSM remote control = control unit +



mode relay + mode GSM
for heating and heating of sanitary water with GSM



remote control = control unit + mode relay + mode TUV
(sanitary water) + mode GSM.

Control unit works with below mentioned inlet signals:

temperature of heating water (sensor NTC)



outside temperature (sensor NTC)



room temperature (sensor NTC)



temperature of sanitary water (sensor NTC) only if the

1.7.4 Antifreeze protection of the boiler

Antifreeze protection of the boiler

This function protects the boiler against freeze and is



active in the mode STAND-BY.
Circulation pump and the boiler are in operation, if



temperature of heating water decreases below 5 °C. In
this case the boiler assures minimal level o heating and
the system is mildly warm, the boiler heats to 15 °C
temperature of heating water and after that the boiler
set back to mode that it start to operate from. Pump
running of is active.

In case that the boiler is in the summer mode



(permanent heating of storage water tank) and the
temperature of heating water decreases below 5 °C
then the antifreeze protection function is activated for
heating system, after the boiler catch the temperature
15 °C, then the 3-ways valve go back to the position for
heating of sanitary water and pump running of is also
active.

If the boiler is switched off or out of electric
supply, this function is not active.

Unlocking protection of heating system

It is active at all times if the circulation pump or



3-ways valve is more than 24 hours out off
operation to protect blocking of the pump or
the valve due to its small parts. This function
avoids blocking of the pump rotor in mode

STAND-BY and elongates its lifetime.
The pump works 1 time per day for 10 s.



1.7.5 Safety function of the boiler

Control unit

The control unit is designed according to valid EU norms



and is certified.

The control unit has a protection against below and



over voltage
The control unit is protected by system Watch-Dog-



Timer with time 512 ms against its processor “blocking”.
In case that the processor is blocking the automatic
reset function is activated and then the program is
going with all parameters set from the point where it
was broken

Protection against overheating

The boiler has an emergency thermostat set for 100 °C.



In case of boiler overheating heating elements are put
out of operation independently to the control unit. This
breakdown is signaling on the display as a critical

breakdown No. 5.
This breakdown could be repaired only by authorized
service man.

Protection against lost of heating water pressure

The boiler equipped with a pressure switcher which



control minimal pressure in heating system 0,4 bar,

when the function reliability of deaerate valves is

assured, it means that the boiler has sufficient volume

of water.

In case of lost of heating water pressure below 0,4 bar



the boiler signs the critical breakdown No. 4 and

heating elements are put out of operation

independently to the control unit.

This breakdown could be repaired after the control of



tightness of water ways and after water filling over 0,4

bar. After that the boiler is automatically reset and

returned to normal operation.

Boiler protection against over and below voltage
in supply electrical net

The control unit is equipped with function assuring



putting the boiler out of operation if the voltage is below

150 V or over 250 V. This stage is marked on the display

like a critical breakdown No. 8. Below voltage is not

marked on the display.

When the voltage is OK = in the scale 150 250 V, the



boiler returns to normal operation.

Boiler protection against overpressure of heating
water

The boiler pump is equipped with pressure safety valve
set for 3 bars. In case of the overpressure more than 3
bars the leakage of water occurs from the valve till the
pressure of water in heating system is not below
maximal requested level.
This valve is in its operation automatically.
