Floor heating + Radiator
Outdoor
Connect floor heating or radiator to 2 circuits through buffer tank as shown in figure.
Install pumps and thermistors (specified by Panasonic) on both circuits.
Install mixing valve in the circuit with lower temperature among the 2 circuits.
(Generally, if install floor heating and radiator circuit at 2 zones, install mixing valve in floor heating circuit.)
Remote controller is installed on indoor unit.
For temperature setting, select circulation water temperature for both circuits.
Both circuits can set circulation water temperature independently.
Install buffer tank thermistor 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).
Mind that if there is no mixing valve at the secondary side, the circulation water temperature may get higher than
setting temperature.
Floor heating + Swimming pool
Outdoor
Indoor
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.
