Instructions ECL Comfort 210 / 310, communication description
The minimum value for the parameters in Table 6-3 is 10 °C and
the maximum value is 150 °C. It is possible to set the flow
temperature higher than the maximum flow temperature setting
(default 90 °C) but the flow temperature will still be capped by the
maximum. The slope will possibly still be affected depending on
the other flow temperature points.
Table 6-3 is for circuit 1 parameters. For circuit 2 add 1000 to the
addresses. For circuit 3 add 2000 to the addresses.
Not all applications or circuits have a heat curve.
6.6 Time and date
The time and date parameters are located in the PNU range 64045
– 64049.
Table 6-4:
Parameter PNU
Hour [0;23] 64045
Minute [0;59] 64046
Day [1;31] 64047
Month [1;12] 64048
Year [2009;2099] 64049
Automatic summer time [0;1] 10198
6.6.1 Rules for setting time
The valid date range is from 01/01/2009 to 31/12/2099 using the
Gregorian calendar.
When a new time is set, the seconds are internally reset to 0 in the
controller. It is not possible to externally set seconds.
If an attempt is made to set an invalid time, it will be rejected.
When adjusting the date it is necessary to set a valid date.
Example: If the date is 30/3 and it must be set to 28/2, it is
necessary to change the day first before changing the month
because 30/2 is not a valid date. Likewise care must be taken
during leap years. If the set date is 29/2/2012 then it is necessary to
change the day before changing the year because 29/2/2011 is not
a valid date.
