SyScroll 20 Air Evo. Air cooled inverter Driven Water Heat Pump

• Wide load variation capability.
• Cooling operation → down to 30 % and up to 140%
of nominal capacity.
• Heating operation → down to 40% and up to 130% of
nominal capacity.
• Great accuracy in maintaining desired set-point.
• Unit optimization for heating operation both for fan coil
and floor application.
• Excellent efficiency performances both at full and partial
load (EER/COP/SEER/SCOP).
• Wide operating limits in heating mode:
Min outdoor ambient temperature → -15 [°C].
Max leaving water temperature → 55 [°C].
• Simple refrigerant circuit with easy access to inner components for maintenance purpose.
• Aeraulic independence between refrigerant circuit and
condensing side.
• New fan motors (Erp 2015 compliant) with integrated
grill, nozzle and condensers.
• Possibility to manage domestic hot water production,
auxiliary heating source, second set-point zone field
components
• Key points
Several options / accessories provided with standard delivery:
• Fan speed control → cooling operation with low OAT /
heating operation with high OAT.
• Electronic expansion valve → precision in SH control.
• ModBus interface → supervision ready.
• Phase sequence control algorithm → safe electric installation.
• Modulating capacity control → precision in water setpoint control.
• Soft-start function → low inrush current.
• Power factor correction function → low input current
distortion.
• Coil blue fin treatment → effective water drainage during defrost.
• Coil guard → protection during transport and installation.
• Double set-point→ different daily profiles.
• Dynamic set-point → water profile in accordance with
outdoor air temperature or current / voltage signal.
• Water filter → protection against impurities.
• Water differential pressure switch → protection against
low water flow.
• Rubber pads → basic vibration attenuation.
