APPENDIX

This section introduces variation of various systems using Air-To-Water Heatpump and actual setting method. 

1-1 Introduce application related to temperature setting.

Temperature setting variation for heating

1. Remote Controller

Mono bloc

Floor heating

Mono bloc

or

Connect fl oor heating or radiator directly to the Mono bloc.
This is the basic form of the most simple system.

2. Room Thermostat

Mono bloc

Mono bloc receive Room Thermo signal 
(ON/OFF) from Remote controller to 
control HP and circulation pump.
There is a build-in thermistor in the 
remote controller.

Floor heating

Mono bloc

or

Connect fl oor heating or radiator directly to the Mono bloc.
Install the remote controller in the room where fl oor heating is installed.
This is an application that uses remote controller as Room Thermostat.

3. External Room Thermostat

4. Room Thermistor

or

Mono bloc

Max: 30m

Thermistor

Mono bloc compare between 
room temperature and setting 
temperature on the Remote 
controller to control HP and 
circulation pump.

Floor heating

Mono bloc

Connect fl oor heating or radiator directly to Mono bloc. 
Install separate external room thermistor (specifi ed by Panasonic) in the room where fl oor heating is installed.
This is an application that uses external room thermistor.

There are 2 kinds of circulation water temperature setting method.

Direct: set direct circulation water temperature (fi xed value)
Compensation curve: set circulation water temperature depends on outdoor ambient temperature

In case of Room thermo or Room thermistor, compensation curve can be set.
In this case, compensation curve is shifted according to the thermo ON/OFF situation.

 

(Example) If room temperature increasing speed is;
very slow 

o

 shift up the compensation curve

very fast 

o

 shift down the compensation curve

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.

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 (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-NS4P).

(CAUTION)

 

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.

This is an application that connects the boiler to the Mono bloc, 
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.
There are 3 modes selectable by remote controller for boiler connection.
Besides that, an application that connects to the DHW tank’s circuit to heat up tank’s hot water is also possible.
(Operation setting of boiler shall be responsible by installer.)
This system requires optional PCB (CZ-NS4P).

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 selecting 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 Mono bloc does NOT exceed 55°C.
Boiler is turned off by safety control when the water temperature of the heating circuit exceed 85°C.
