Buffer tank + Solar
Outdoor
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 (specified by Panasonic).
Solar panel's temperature is detected by solar thermistor (specified 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).
Boiler connection
Outdoor
This is an application that connects the boiler to the Tank Unit, to compensate for insufficient capacity by operate
boiler when outdoor temperature drops & heat pump capacity is insufficient.
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.)
Panasonic is NOT responsible for incorrect or unsafe situation of the boiler system.
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.
