17.4 rf radiofreQuency association of the rfrc01 climate controller With the rfiu01 base
To ensure correct system operation, the rFrc01 climate controller must be "associated" (programmed) for communica-
tion with the rFiu01 base connected to the boiler card.
Proceed as follows:
• Press ip for at least three seconds (section 19.1) to access the "inFo" screen;
• Press oK to scroll the parameter list to "Zone>";
• Press to display "linK>";
• Press the button on the rFiu01 base (near the LED);
• Press oK on the rFrc01 climate controller:
if the display shows "1", rFrc01 and rFiu01 are communicating correctly, press oK;
-
- if the display shows "error" the two units are not communicating (in this case repeat the procedure, or replace
the rFIu01 base),
• Press oK to display the rFchK parameter and view the quality of the communication signal as described in section
17.5., or press ip to exit the programming mode.
17.4.1 Disabling the rF radiofrequency connection between the rFrc01 climate controller and the rFiu01 base
Follow the procedure described in the previous paragraph (17.4). Press
message reMv> underneath.
Press oK to disable the connection (1 disappears from the display).
17.5 displaying the Quality of the rf radiofreQuency signal betWeen the rfrc01 climate controller and the rfiu01 base
The quality of the rF communication signal depends on the type and layout of the system and may be affected by
the presence of metal obstacles and/or intense radio transmissions. An indicative quality level of rF communication
between the climate controller and the base can be displayed:
0 = rF connection absent, no communication possible;
1 = rF connection present but communication level insufficient;
2 = rF connection present, communication level sufficient;
3 = rF connection present, communication level fair;
4 = rF connection present, communication level excellent;
Position the base in order to obtain communication level rF=4 as this will guarantee correct system operation.
17.6 replacing the batteries in the remote control unit (fig. 1.1)
replace the batteries when (
To ensure the remote control unit works correctly, however, change the batteries once a year. To replace the batteries,
see figure 1.1 in chapter 3.
caution
If the display does not work correctly, try changing the batteries.
A Qualified Service Engineer may adapt this boiler to operate with natural gas (G. 20) or with liquid gas (G. 31).
The procedure for calibrating the pressure regulator may vary according to the type of gas valve fitted (HONEY WELL or
SIT; see figure 13).
Carry out the following ope rations in the given sequence:
A) substitute the burner injectors;
B) change the modulator voltage;
C) proceed with a new max. and min. setting of the pressure adjusting device.
a) substitute the main burner injectors
• carefully pull the main burner out of its seat;
• substitute the main burner injectors and make sure you tighten them to avoid leakage. The diameters of the injectors
are specified in table 1.
