CONTROL PANEL
General Display switch
hydrometer
The control panel is composed of: display, function selection keys, general switch and the hydrometer it si placed in the lower left corner in front of the unit (see image above).
Using analogical hydrometer
The analogical hydrometer control panel has a dial with unit of measure in a bar, by 0 to 6 bar. The water pressure in the heating system is indicated by the index of the black arrow. The optimum pressure for the system is between 1 and 1,5 bar. More then 1,5 bar you can have a maximum pressure of the 2 bar (maximum expansion of the system during the rise in temperature). More than 2 bar pressure the system is not in the range of operation, and the mechanical safety valve (preset to 3 bar) can start to lose water (to access the valves remove the knockout openings at the valves, see page 2 hydraulic installation diagram).
The minimum op rating pressure is 0,8 bar (+/-0,2 bar). The differential positive or negative tolerance is due to the operation of the water pressure switch with fixed setting. .

CONTROL OF MAIN HEAT EXCHANGER (BOILER BODY)
According to the required power during the heat request, the controls by G1 to G3, G5 and G5B related to the main exchanger are turned on all or partially. The actuaction of each control is reduced to a lapse of 4 seconds. Higher is the required power, more the control will remain operative in this lapse. The power in heating or during a sanitary request is calculated by PID algorithm. Please see in the pictures below two examples related to 40% and 60% of total power (12 kW).

CONTROL OF EXTERNAL PROBE Installation and functioning at sliding temperature
For the connection of the External Probe, it shall be used the Original Kit FIAMMA code F.532 provided in the accessories of the electric boilers Elektra. The electrical connection shall be done in the external terminal at the general electric panel already prearranged in the standard cabling of the boiler. The connection must be carried out with junction cables and wires having a minimum section of 1,5 mm and, if possible, avoiding the insertion along with electric lines, digital lines of inverter or other not compatible.
After the connection the external probe must be enabled by means of the introduction of a variation of P1 parameter, changed from 0 to 1. Then the setpoint chased by the heating delivery probe will be calculated as follows: T ch [°C] = [( T room [°C] – T ext [°C]) * dc/10 ] + T room [°C]
T ch : heating setpoint calculated by the system T room : ambient temperature set by the user T ext : outside temperature measured by the probe dc : dispersion coefficient of the building can be set by parameter P2 .

Examples of curves with T room set at 20°C and JP7 = 1
In case the delivery probe measures a temperature lower than 7°C, the circulator is activated. If the temperature goes down the value of 4°C, the primary exchanger (boiler body) is turned on until bringing the outlet temperature to 20°C. The antifreeze function is active also with the boiler turned OFF (function in standby mode but with bright switch on).
16
REQUEST HEATING
At the closing of the room thermostat contact, if the board is in winter mode, the system pump is only activated if the primary exchanger temperature is higher than the set temperature using the parameter P6 . If the temperature value detected by the primary exchanger probe is lower than the flow temperature setpoint set, the triacs are turned on in sequence according to the power required. This only occurs after a time set by parameter P5 , to allow for example the opening of eventual zone valves. The instantaneous power of the boiler and the control of the triac G1÷G5B is by PID controller. At the end of the request, the circulator remains powered for a time equal to the value set by parameter P4 .
ISTRUCTION PUMP
The pump consists of a hydraulic system, a wet rotor motor with permanent magnet rotor and an electronic control module with integrated frequency converter. The control module contains a control button, the pump is also equipped with an LED indicator to display the operating status of the pump.
Functions
All functions can be set, activated or deactivated using the command button.
Variable pressure difference ( ∆ p-v): The delivery value of the pressure difference is increased linearly between 1⁄2 H and H in the permitted flow range. The value of the pressure difference generated by the pump is adjusted to the set delivery value. This control mode is particularly suitable for heating systems with radiators, since the flow noise on the thermostatic valves is reduced.
Difference of constant pressure ( ∆ p-c): The delivery value of the pressure difference H is maintained, within the permissible flow range, constantly on the set delivery value up to the maximum characteristic curve. This control mode is recommended for underfloor heating systems or older heating systems with large pipes, but also for all other applications that do not have variable plant characteristic curves, such as boiler drain
D egassing function
During the execution of the automatic venting function (10 min.) The pump works from time to time at low and high speed and transports the air formations out of the pump directly to the system vent valve.
17
Filling and venting
Fill and vent the system correctly. If direct venting of the rotor compartment is necessary, the venting function can be started manually. By turning the control button to the central position, to the vent symbol, the vent function is activated after 3 seconds. The duration of the vent function is 10 minutes and is shown by the rapid flashing of the green LED. A certain noise may occur during the venting function.
The process can be interrupted at will by turning the button. At the end of the 10 minutes the pump stops and automatically switches to the ∆ p-c max. setting mode.
Then you need to set the adjustment mode and prevalence if the pump does not have to continue to operate in ∆ p-c max mode.
NOTE: The vent function removes the air accumulated in the pump rotor compartment. This function does not affect the heating system.
Setting the adjustment mode
By turning the control button, the adjustment mode symbol is selected and the desired prevalence/ constant speed is set.
Variable pressure difference ( ∆ p-v): To the left of the central position, the pump is set to ∆ p-v control mode.
Difference of constant pressure ( ∆ p-c): To the right of the central position, the pump is set to ∆ p-v control mode.

HEAD SCREEN APPLICATION
To select the use of the main board on application for screed heater, JP10 = 1 is used. With the room thermostat open, the system displays the temperature measured by the probe of the primary exchanger and the operating state in which it is located ( ST.By = stand-by).
19
When the user closes the contact of the room thermostat, the system requests the setting of the system design temperature that will be used for the execution of the second part of the test ( t.1b = test 1 - second part) according to UNI EN 1264-4, paragraph 4.1.4, with a duration of 96 hours.
With the keys + I ( J2 ) and - I ( J3 ) you set the project value for the system, then when the MODE ( J4 ) key is pressed, the system starts the first part of the test ( t.1A = test 1 - first part) or for 72 hours the delivery temperature is kept at a value of 23°C (from 20°C to maximum 25°C). The circulator is activated when the temperature of 20°C is exceeded (anti-condensation). When the circulator is not active, the system heats the main heat exchanger with a maximum power of 6 kW. The operating hours count is when the temperature measured by the primary exchanger probe has a value above 20°C and stops if it falls below this threshold. The system memorizes the elapsed test time with a resolution of 15 minutes. On the display the wording t.1A alternateswiththenumberoftesthoursperformed(xxx h ).Whenthetemperaturesisbelow 20°C, the number of hours is replaced with the word " --- " to indicate that the count is not advanced. The modulation bar is displayed at the end of the pre-heating phase of the primary exchanger.
Once the 72 hours of testing have been completed, the system automatically modifies the set-point to be followed at the value set before starting the test (design temperature). The display shows that the second part of the test is being executed with the text t.1b . The test hours counting continues from the value of 72 hours of the first part only if the temperature measured by the probe of the main heat exchanger is greater than or equal to the design temperature, the other way around the number of hours is replaced with the words " --- " to indicate that the count does not advance. During this part of the test, the system follows the set-point value set to + 1°C and stops the power resistors if the measured temperature exceeds the set-point by 3°C.At the end of the 168 hours that make up the test 1(72 hours for part a and 96 hours for b), the system stops the power resistors and the system circulator. At this point the user is asked to set a set-point in hours ( time ). This time is used, ifnecessary,forthecontinuationofthetest( t. 2 test2)atthedesigntemperatureofthesystem.
20
If you wish to continue with the second part of the test, set the set point in hours using the keys + I ( J2 ) and - I ( J3 ) and confirm the value set with MODE ( J4 ). The display shows that the second testisbeingcarriedoutwiththetext t. 2 .Thecountofthetesthoursstartsagainfromzeroandtakes place only if the temperature measured by the probe of the main heat exchanger is higher than or equal to the design temperature, the other way around the number of hours is replaced with the word " --- " to indicate that the count it does not advance. The circulator is activated when the temperature of 20°C is exceeded (anti-condensation). When the circulator is not active, the system heats the main heat exchanger with a maximum power of 6 kW. The modulation bar is displayed at the end of the pre-heating phase of the primary exchanger. At the end of the set time, the system stops the power resistorsandthesystemcirculatoranddisplaysthe test end .Toallowthesystemtorepeatthetest, simply press the room thermostat or, using the ON-OFF ( J7 ) key, switch off and on again.
At any time the current test can be terminated by opening the room thermostat. At the new closing the system starts again from the beginning. In the event of a power failure, the system resumes from where it left off when it is restored.

FUNCTIONING WITH REMOTE CONTROL ENCRONO OT1 or OT2
Ele k tra.. N 016 , can be connected by means of its board and an additional module to install on a prearranged part, to a compatible remote control device Opentherm®, like Encrono OT1 or OT2. This can be obtained by means of the interface board (additional module). When the board finds the connection with the remote control, on the LCD display appears the symbol M. The compatible remote control OpenTherm becomes the master of the entire system, therefore almost all the functionalities, as the setting of heating and hot sanitary water set-point or the control of system status, are directly executable by it, in relation with the kind of application on which the board is used. By means of the remote control it is possible to restore ( RESET ) the system from the non- volatile lock status. The communication between the remote control and the electronic board fitted with D.E.S. system can be interrupted in the following ways: Interruption of the connection between remote control and board: in this case, after 1 minute, the board starts to work in local mode. Noise on communication cable between remote control and board: in this case it is possible that remote control and board do not manage to communicate (wrong data interpretation), therefore, after a certain lapse appears the related error signal. If the noise on the communication cable ends, the dialog between remote control and the board is automatically restored and the malfunction disappears.
TRANSPARENT PARAMETERS
This function is available only with the use of remote control OT2. The digital electronic PCB is equipped with 10 parameters adjustable by the installer, in order to set the functioning of the system in conformity to the final application. The parameters have the same meaning of the ones described in the table “parameters”.

FUNCTIONING OF BOILER ELEKTRA WITH REMOTE CONTROL
The actuation of heating mode takes place after an heating request from remote control (value of heating setpoint calculated by remote control higher than heating setpoint set by the user on remote control divided by two) and in the winter mode status.
