Aquarea. PCB for additional functions.

The optional PCB enables additional control functions for Aquarea heat pumps.

Functions available through the connection of the Optional PCB to the Main PCB:
2-zone control, with 2 mixing valves, 2 pumps and 2 room thermostats or sensors.
Control of swimming pool.
Buffer tank temperature sensor (available in the main controller for K and L Generations).
Solar thermal control.
External error signal output.
0-10V signal for heat pump demand control.
SG ready (1).
Stop compressor by external compressor switch.
Switch heating and cooling by external heat-cool switch.

(1) Aquarea H and J Generations heat pumps in combination with the optional PCB CZ-NSP4 hold the SG Ready Label (Smart Grid Ready Label), given by Bundesverband Warmepumpe (German Heat Pump Association). This Label shows the real capacity of Aquarea to be connected in an intelligent grid control.
