by the driver of the boiler. Heating the domestic water with the
boiler cooperation with the tank of domestic water is as follows:
•
water temperature sensor in the tank indicates the water
temperature drop below the set temperature by the hysteresis
value of domestic water [parameter P18] (e.g. due to opening of
inlet tap valve);
•
boiler control unit makes the three-way valve to draw the heating
water to a short circuit while giving a signal to the spark generator
and gas valve;
•
heating water flows through the coil of tank (short circuit);
•
driver of the boiler controls the heating water temperature in an
optimal way so as not to exceed a permissible value. If the heating
water temperature exceeds 97
°C
, an additional temperature limiter
is activated (item 2.16), the burner is turned off until the hot water
temperature drops below 81°C
;
•
after exceeding the set water temperature in the tank the boiler
controller gets distorted the three-way valve for long circuit and at
fulfillment of the following conditions the heating water is pumped
into the central heating system:
- heating water temperature is lower than the set temperature
-
room thermostat gives a signal “heat”.
Hot water temperature at the point of consumption may differ from
the set value, and therefore it is advisable to install a mixing valve for
domestic hot water systems.
When using a water tank in the ECOCONDENS CRYSTAL
100 boiler , to ensure proper operation of the boiler the
required coil power in the tank is minimum 25kW.
To eradicate legionella bacteria in the tray, the boiler is
turned on every 168h to work with the tank and heats
water to 60°C.
To prevent excessive energy
consumption, the timing function is reset when the
water temperature in tank will reach 60
°
C during
normal use.
2.5 Description of the control panel
The boiler control panel has 7 function buttons and an LCD display
for displaying boiler settings and information about operating states
of the boiler.

3. BOILER INSTALLATION
Important safety information
FAUILER TO COMPLY WITH LISTED RECOMMENDATION WILL
RESULT IN LOSS OF THE WARRANTY
- The boiler must be installed by an authorized service company
accordingly with local regulations;
- After the boiler installation check the tightness of all connections of
gas and water systems;
- Service company is responsible for the proper installation of the
boiler;
- Installation of the boiler must be made so as not to cause any
tension of the installation that may cause increased volume of work;
- Packages should not be left within reach of children;
- Check whether the chimney is perfectly clean and free of dirt;
- The boiler must be connected to the heating system corresponding
to its power;
- Check whether the boiler is adapted to burn a certain type of gas;
- Check the water hardness, if it exceeds 20
̊
F (1F = 10 mg calcium
carbonate per liter of water) proceed to the water softening;
- It is mandatory to thoroughly clean all installation wires in order to
eliminate possible residues from threading, welding, solvents or
sludge and any other contaminants from the heating circuit.
