Presentation of the pAD

pAD is the wall-mounted LCD room terminal with icon-based display for use with pCO
controllers. It is available in two models: with temperature sensor or temperature +
humidity sensors.
Depending on the model, pAD can be connected to the pLAN port or Field Bus RS485
port. The clock, available on some models for managing time bands, and the attractive
design, make the display suitable for residential or commercial applications.
