(1) Above mentioned power supply of the hydro box is for the backup heater only. The Switch box & pump of the hydrobox are supplied via the outdoor unit. The optional domestic warm water
tank has a separate power supply.
(3) Select diameter and type according to national and local regulations
(4) For more details of the voltage range and current refer to installation manual
(5) Voltage: 230V / Maximum current: 100mA / Minimum 0,75mm²
(6) Depends on thermostat type, refer to installation manual
(7) Wire included in option *KHW*
(8) In accordance with EN/IEC 61000-3-11(*), it may be necessary to consult the distribution network operator to ensure that the equipment is connected only to a supply with Zsys(***) ≤Zmax
(9) Equipment complying with EN/IEC 61000-3-12 (**)
(*) : European/International Technical Standard setting the limits for voltage changes, voltage fluctuations and flicker in public low-voltage supply systems for equipment with rated current ≤75A.
(**) :
European/International Technical Standard setting the limits for harmonic currents produced by equipment connected to public low-voltage systems with input current >16A and ≤75A per phase.
(***) : System impedance
