Activa rooftop details & features
PCB board
The new control board keeps same features and benets as
YKlon V3 (see pg. 127) and adds new logical to control the
tandem circuit, the new options (heat recovery, return fan) and
the possibility to communicate with BMS system as standard
(N2Open).
Condenser fan
New condenser fans with high technology blades and outdoor
bell that reduce the turbulences in the air and therefore increase
the efciency and improve the noise level performance.
PCB board
Return fan
Located in a special roof curb underneath the rooftop, it works
simultaneously with the indoor fan in order to balance the amount
of air supplied to and removed from the space. It is the best
suited for systems with high return path static pressures.
Also, incorporates EC technology and a differential pressure gauge
to easy set up and maintain automatically the working point in the
installation.
Tandem scroll compressors
Tandem compressors conguration allows the unit to operate at
partial load (only with one compressor) with higher efciency and
increases the working range up to +52°C ambient temperature.
