N ew defrost control
In order to shorten the defrost time, the new defrost control improves operation of
①E lectric E xpansion V alve (E E V ) control
②Water pump control
In the case of outside air temperature above -5℃, the water
pump is stopped during defrost operation.
Limited unit control
In the case of master - slave system, power input and therefore also capacity output, can be
controlled by reducing the number of heat pump water heaters running.
Refer to page 152 for the setting method.
All units defrost
All the heat pump water heaters connected in a master - slave configuration can be
symchronise to perform defrost at the same time.
This avoids some adjacent units to recirculate cold air during defrost, while others
are still running on top up or fill up operation.
Refer to page 152 for the setting method.
E xternal output of hot
water amount
An external output signal can be sent out when the hot water amount has reached
a set point programmed by the user using the schedule setting.
This allows better interaction with external heat sources.
Refer to page 153 for the setting method.
