Floor heating + Swimming pool
Indoor
Outdoor
Connect floor heating and swimming pool to 2 circuits through buffer tank as shown in figure.
Install mixing valves, pumps and thermistors (specified by Panasonic) on both circuits.
Then, install additional pool heat exchanger, pool pump and pool sensor on pool circuit.
Remove remote controller from indoor unit and install in room where floor heating is installed. Circulation water temperature of floor heating
and swimming pool can be set independently.
Install buffer tank sensor on buffer tank.
It requires connection setting of buffer tank and T temperature setting at heating operation separately. This system requires the
optional PCB (CZ-NS4P).
 Must connect swimming pool to "Zone 2".
If it is connected to swimming pool, operation of pool will stop when "Cooling" is operated.
Swimming pool only
Outdoor
Indoor
This is an application that connects to the swimming pool only.
Connects pool heat exchanger directly to indoor unit without
using buffer tank.
Install pool pump and pool sensor (specified by Panasonic) at secondary side of the pool heat exchanger.
Remove remote controller from indoor unit and install in room where floor heating is installed.
Temperature of swimming pool can be set independently.
This system requires the optional PCB (CZ-NS4P).
In this application, cooling mode cannot be selected. (not display on remote controller)
Simple 2 zone (Floor heating + Radiator)
Outdoor
This is an example of simple 2 zone control without using buffer tank.
Built-in pump from indoor unit served as a pump in zone 1.
Install mixing valve, pump and thermistor (specified by Panasonic) on zone 2 circuit.
Please be sure to assign high temperature side to zone 1 as temperature of zone 1 cannot be adjusted.
Zone 1 thermistor is required to display temperature of zone 1 on remote controller.
Circulation water temperature of both circuits can be set independently.
(However, temperature of high temperature side and low temperature side cannot be reversed)
This system requires the optional PCB (CZ-NS4P).
(CAUTION)
•
Thermistor 1 does not affect operation directly. But error happens if it is not installed.
•
Please adjust flow rate of zone 1 and zone 2 to be in balance. If it is not adjusted correctly, it may affects the performance.
(If zone 2 pump flow rate is too high, there is possibility that no hot water flowing to zone 1.)
Flow rate can be confirmed by "Actuator Check" from maintenance menu.
