Tank Hold
Warm
Defines the value of a storage cylinder's
delta T required for temperature mainte-
nance. For instance, if set at 3 degrees,
when the storage cylinder is at a set-point
value minus 3 degrees, the thermal mod-
ule is switched on at minimum power to
maintain the temperature to the set-point
plus hysteresis. If this parameter is kept
the same as Par. 36, this function is inac-
tive and the thermal module is switched
on to the maximum power envisaged for
the DHW circuit.

Priority
Defines the priority type:
0 = Time: time priority between the two
circuits defined by Par. 43;
1 = Off: priority for CH;
2 = On: priority for DHW;
3 = Parallel: parallel priority managed on
the basis of the primary circuit's temper-
ature compared to the heating circuit's
set-point.
