Panasonic UD3 3.5 KW CS-Z35UD3EAW/CU-Z35UBEA Air To Air Heat Pump
Low static pressure, concealed, with a compact indoor unit, only 200 mm high
Designed for homes, offices, retail and catering, this ducted unit is ideal for small spaces where air conditioning and heating need to be integrated very delicately to ensure maximum comfort and efficiency.
This channel unit can also be connected to KNX, Modbus interfaces for easy integration into BMS systems. These interfaces have secondary contacts (on/off, error messages) and are therefore easy to integrate.
Channel type units can be controlled via KNX and Modbus
Eco mode saves 20% energy
Extremely compact indoor units that do not lose static pressure (only 200 mm high)
Weekly timer, 42 settings per week
A simple test mode for troubleshooting
With drainage pump

1) EER and COP indicators are calculated according to standard EN14511.2) Energy label scale from A+++ to D. 3) Annual energy consumption calculated according to EU/626/2011. 4) The pressure value of the internal block was measured at a distance of 1.5 m from the bottom of the block, when the channel block is installed at a distance of 1 m on the suction side and 2 m on the discharge side. The field unit values are measured 1 m from the front of the main body and 1 m from the back. Sound pressure measured according to JIS C 9612. 5) Add 100mm indoor unit and 70mm outdoor unit to the pipe outlet. 6) When the outdoor unit is installed higher than the indoor unit. 7) The specifications listed in the table show values obtained at a pressure of 25 Pa (2.5 mmAq) which apply to the manufacturer’s intended settings. Turn the PCB switch from Hi to S-Hi to get the pressure above 6.0mmAq.
