By applying 9 sensors on the cylinder at installation, it is available to control the HP unit for the operation to store
hot water or for the operation to top up at 10% intervals of HW amount.
In case that 9 sensors can not be applied on the cylinder, the unit cannot detect HW amount at 10% intervals and it
can detect only the preset HW amount shown in following table depending on the applying number of sensors.

*1 Recommendable number of sensors is 9pcs.
If the number of sensors is less than 9pcs, the hot water amount cannot be detected correctly.
*2 The sensor which detects 100% of HW amount shall be applied to the position within the range of sensitive vol-
ume with consideration of dead volume which is 10% of total volume of cylinder.
H
owever, HW amount can be set at 10% intervals arbitrarily with RC despite of the number of sensors applied.
Therefore, in such case, please take note that the unit may not be controlled for the operation to store hot water or
for the operation to top up according to the set HW amount you intended.
Ex) In case of applying 3 sensors on the cylinder.
Heat pump unit can detect only 20%, 60% and 100% of HW amount in the cylinder.
Therefore, even though 80% of HW amount is set with schedule setting, the HP unit cannot stop at storing 80% of
HW amount and it still keeps on operating until storing 100% of HW amount.
And if 40% of HW amount is set for the operation to top up, HP unit cannot start operation to top up until HW
amount decreases to 20%.
