Staggered defrosts
The function is used to perform a series of daily defrosts by setting just the first using parameter td1 and
then indicating the number of defrosts per day using parameter d1S. The controller automatically
schedules all the defrosts to be performed at regular intervals over the 24 hours following the event
defined by td1. The same applies to td2 and d2S.

Remember that the sub-parameter “d_” of td1 (td2) defines the defrost day, as follows:
d_ = Defrost - day
0 = event disabled
9 = from Monday to Saturday
1 to 7 = Monday to Sunday
10 = Saturday & Sunday
8 = Monday to Friday
11 = every day
Note:
l
if event td1 includes a series of days, the programming always ends at 24.00 on the last day. If
event td1 includes one day only, the programming ends at 24.00 on the same day;
l
if both td1 and td2 are set, when the defrost events overlap, only the sequence of defrosts that
start first are performed..

The parameter determine whether or not, in a local network, MPXone awaits a start/end defrost signal
from the Master at the start/end of the defrost.

For defrosts that end by temperature (d0=0) , this enables the end defrost by timeout signals Ed1 and
