Floor heating + Swimming pool
Outdoor
Connect fl oor heating and swimming pool to 2 circuits through buffer tank as shown in fi gure.
Install mixing valves, pumps and thermistors (specifi ed 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 fl oor heating is installed. Circulation water temperature of fl oor 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-NS5P).
Must connect swimming pool to "Zone 2".
If it is connected to swimming pool, operation of pool will stop when "Cooling" is operated.
NOTE : Buffer tank thermistor must be connected to main indoor PCB only.
Swimming pool only
Outdoor
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 (specifi ed by Panasonic) at secondary side of the pool heat exchanger.
Remove remote controller from Indoor Unit and install in room where fl oor heating is installed.
Temperature of swimming pool can be set independently.
This system requires the Optional PCB (CZ-NS5P).
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 (specifi ed 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-NS5P).
(NOTE)
• Thermistor 1 does not affect operation directly. But error happens if it is not installed.
• Please adjust fl ow 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 fl ow rate is too high, there is possibility that no hot water fl owing to zone 1.)
Flow rate can be confi rmed by "Actuator Check" from maintenance menu.
