13.1.5 - Connection board 885 IF (on
request)
Board 885 IF is supplied on request for all models (see detail
“13” in figures 3-3, 3-5 and 3-7).
The board enables:
1.- control of boilers via 0-10 Vdc analogue signal;
2.- control of boilers via digital signal by MODBUS
communication;
3.- cascade connection of boilers up to a number of 8 units
(see section 13.4)
0-10 Vdc type dialogue (on request)
Board 885 IF allows the boiler to be controlled through 0-10
Vdc dialogue proceeding as shown below:
1.- Install the board as required by the instructions provided;
2.- Go into the “installer menu” as described in section 17.15
and set parameter
2003
= 4;
3.- Now the boiler can be controlled via the 0-10 Vdc signal
according to the rules shown in figure 13-3;
MODBUS type dialogue (on request)
Board 885 IF allows the boiler to be controlled through
MODBUS dialogue proceeding as shown in the instructions
supplied on request:
13.1.6 - Alarm contact
The alarm contact only works if the 885 IF board is fitted (see
figures 3-3, 3-5, 3-7 detail “13”) and solely reflects the status
of burner 1 (Master). In the event of one of the burners 2, 3
or 4 being blocked, it is not detected by the alarm contact.
13.2 - Connecting MYDENS
boiler to storage tank
The MYDENS model boiler must be connected to a
storage tank to produce domestic hot water.
The hydraulic connections must be made as per figure 10-2
or similar.
Proceed as follows for the electrical connections (refer to
figures 13-4 and 13-5):
1.- Disconnect the electric power supply from the boiler;
2.- Lay a two-pole electric cable with a minimum cross-section
of 1.5 mm², which goes from the boiler to the storage tank
temperature sensor and connect it on the boiler to terminals
“12” and “13” (SB);
3.- Connect the other end of the cable to the storage tank
temperature sensor;
4.- Insert the temperature sensor probe inside the storage
tank sample point (see figure 10-2, detail “31”).
5.- Set parameter
3012
to value “1” (see section 20)
6.- electrically connect the storage tank pump to terminals
“107” and “108” of the boiler (see figures 13-4 and 13-5).
The temperature of the water stored inside the storage tank
can be selected by the user from a range of between 40°C
and 60°C.
WARNING! A hot water temperature exceeding
51°C may cause permanent injury/damage to persons,
animals and objects.
In particular, protect children, the elderly and people
with disabilities against any possible risks of scalds,
by inserting devices that limit the usage temperature of
the DHW to users.
13.2.1 - Precedence to production of DHW
The boiler leaves the factory set with total precedence given
to the production of domestic hot water. This means that the
boiler operates in DHW mode until it reaches the temperature
demanded by the storage tank connected. Because of this
the aforementioned setting could lead to a cooling of the
environment to be heated. Once the DHW demand has been
satisfied, the boiler automatically goes back to working for the
central heating circuit.
