4.1. SYSTEM FILLING
Some examples, purely indicative of the installation, are reported at chapter 1, while the connections to the thermoproduct are reported at
chapter 13.
WARNING: The Modulo All Inclusive system has to be filled only by means of the tap (pos. 3). When the manometer (M) shows a
pressure of 1-1,2 bar, close the tap.
During this phase, open all the bleed valves of the All Inclusive Module (SF) and the radiators to prevent the formation of air sacks,
checking the outlet of water to avoid unpleasant floodings.
The installation watertight test has to be performed with the normal cold operating pressure (please refer to the instruction manual of the
thermoproduct matched with the Modulo All Inclusive).
The installation must always be full of water even when the thermo-fireplace is not used. During winter season the non use has
to be faced by adding antifreeze substances.
5. ELECTRIC CONNECTION
The control unit and the plant must be installed and connected by authorized personnel according to the standards in force.
Connect the feeding cable of the switchboard with an electronic bipolar switch respecting at least a 3 mm distance between the contacts
(power supply 230V~ 50 / 60Hz, it is necessary to provide for the correct connection to the grounding plant).
WARNING: The COMMAND must be connected to the mains with a differential line cut-off switch according to the regulations in force.
Correct operation of the appliance is only guaranteed for pumps and valves approved by La Nordica. La Nordica is not liable for any
improper use of the appliance.
WARNING: In any case, the power cable has to be replaced by authorised personnel ONLY (entitled by La Nordica):
authorised dealers and/or fitter.
6. DIGITAL ELECTRONIC CONTROLLER FOR WATER HEATERS
This digital electronic device controls the activation of two circulating pumps and manages the 3-way valve in the All Inclusive Module.
The digital controller, as well as controlling the water temperature, also manages any blockage of the pumps in the All Inclusive Module.
The COMFORT function obtains a considerable increase in the system water temperature compared to the NORMAL function.
The internal menu can be used to:
• set the language used to show information on the display (IT-EN-DE-FR);
• set the temperature in °C o °F;
• enable or disable the alarm buzzer (Buzzer);
• change display brightness;
• access the technical menu.
WARNING: the parameters in the technical menu should never be modified. Such operation must only be performed by an authorised
La NORDICA S.p.A. service centre.
La NORDICA S.p.A. is not liable for product malfunctions due to the parameters in the technical menu being modified without
authorisation.
6.1. HOT WATER TEMPERATURE
The water temperature is shown on the display by pressing and holding button T2 (see chapter 10).
NOTE: The circulating pump activation temperature is a factory setting.
In the event of excess water temperature the device warns the user with an indicator light and an audible signal; the latter may be enabled
or disabled via the BUZZER function in the MENU.
See EXCESS TEMPERATURE ALARM.
6.2. COMFORT
Pressing and holding button T3 activates the COMFORT function.
When the COMFORT function is active, LED 2 flashes and the function remains active for 15 minutes; if the maximum water temperature
is reached in this time, the LED remains on steady.
After 15 minutes digital controller automatically returns to the NORMAL function (LED 2 off).
NOTE: disable the COMFORT function by pressing and holding button T3
6.3. FROST PROTECTION
The frost protection function is always active on the device and acts by starting the pump when the temperature measured by the probe is
less than 5°C / 41°F (fixed threshold).
When the frost protection function is active, LED 1 Danger comes on and the message "FROST PROTECTION" is shown on the display.
6.4. ANTI-BLOCKAGE
The ANTI-BLOCKAGE function automatically starts the pumps connected to the controller for 30 seconds after an extended period of
inactivity (~96 hours without power being disconnected).
When the ANTI-BLOCKAGE function is activated, the display shows the message "ANTI-BLOCKAGE".
WARNING: to ensure the ANTI-BLOCKAGE function is not disabled, always leave the digital controller connected to the power supply
(the display shows OFF).
