Simple 2 zone (Floor h Radiator)
This is an example of simple 2 zone control without using buffer tank.
Built-in pump from Mono bloc 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).
(NOTE)
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.
