This is an application that connects the buffer tank to the Tank Unit.
Buffer tank’s temperature is detected by buffer tank thermistor (specifi ed by Panasonic).
This system requires Optional PCB (CZ-NS4P).

This is an application that connects the buffer tank to the Tank Unit before connecting to the solar water heater to heat up the tank.
Buffer tank’s temperature is detected by buffer tank thermistor (specifi ed by Panasonic).
Solar panel’s temperature is detected by solar thermistor (specifi ed by Panasonic).
Buffer tank shall use tank with built-in solar heat exchange coil independently.
During winter season, solar pump for circuit protection will be activated continuously. If does not want to activate the solar pump operation,
please use glycol and set the anti-freezing operation start temperature to -20°C.
Heat accumulation operates automatically by comparing the temperature of tank thermistor and solar thermistor.
This system requires Optional PCB (CZ-NS4P).

This is an application that connects the boiler to the Tank Unit, to compensate for insuffi cient capacity by operate boiler when outdoor
temperature drops & heat pump capacity is insuffi cient.
Boiler is connected parallel with heat pump against heating circuit.
Besides that, an application that connects to the DHW tank’s circuit to heat up tank ‘s hot water is also possible.
Boiler output can be control by either SG ready input from optional PCB or Auto control by 3 modes selection pattern.
(Operation setting of boiler shall be responsible by installer.)
This system requires Optional PCB (CZ-NS4P) for SG ready input control or buffer tank temperature control.
Depending on the settings of the boiler, it is recommended to install buffer tank as temperature of circulating water may get higher. ( It must
connect to buffer tank especially when select Advanced Parallel setting.)
WARNING
Panasonic is NOT responsible for incorrect or unsafe situation of the boiler system.
CAUTION
Make sure the boiler and its integration in the system complies with applicable legislation.
Make sure the return water temperature from the heating circuit to the Tank Unit does NOT exceed 55°C.
Boiler is turned off by safety control when the water temperature of the heating circuit exceed 85°C.
