PCB for additional functions CZ-NS4P Panasonic Aquarea

PCB for advanced functions Panasonic CZ-NS4P.

Aquarea heat pumps offer the possibility of connecting useful accessories, such as an external room thermostat or integrating the heat pump into a GLT system using external interfaces. To do this, it is necessary to install the CZ-NS4P electronic base plate.

Additional remote control functions in case of connection to the additional printed circuit CZ-NS4P

The installation of the additional printed circuit CZ-NS4P allows the following additional functions that can or should be selected or adjusted by remote control:

Control and regulation of temperature of a connected inertia deposit

Selecting a connected inertia deposit as well as adjusting the temperature difference (ΔT). It is only available if the inertia deposit is activated.

Regulation of 2 heating circuits (including pool heating)

Selection of the number of heating circuits. If a system with two heating circuits is selected, it should be indicated if the respective heating circuit is used for heating a room or pool. If you have selected "pool", you must adjust a temperature difference "ΔT for swimming pool" between 2 and 10 K.

Disconnection ext. of the outdoor Unit

Dry contact for an external input signal to turn off the compressor in the outdoor Unit (if contact is closed).

The function must be enabled by remote control of the heat pump.

Integration of a solar station

Selection of the inertia deposit or the deACS accumulator for the solar connection or adjustment of the temperature difference of on and off, the temperature of protection against frosts and the upper temperature limit. It is only available if the solar connection is activated.

Notice of external failure

Dry contact for issuing a bug warning signal (if contact is closed) to an external indication unit.

Although the bug has been confirmed by an external indication, the bug warning signal remains active internally.

Power control

Limitation of the operating current according to the current power requirement by a 0–10 volt input signal.

For security reasons, a minimum operating current is created in all devices. For the change between the two power levels, a switching hysteresis of 0.2 V is applied (see table).

Tension values are considered only until the first decimal and are not rounded. The following assignments are applied between the input signal and the power level:

Heating/refrigeration switch

Dry contact for switching between heating (open contact) and cooling (closed contact). The function should be enabled and configured by remote control of the heat pump.
