5 ELECTRICAL AND CONTROL SETTINGS

5.1 GENERAL CHECK

• Make sure that the following conditions related to power supply installation are satisfied:
- The power capacity of the electrical installation is large enough to support the power demand of the YUTAKI system (outdoor
unit + indoor unit + DHW tank (if apply)).
- The power supply voltage is within ±10% of the rated voltage.
- The impedance of the power supply line is low enough to avoid any voltage drop of more than 15% of the rated voltage.
• Following the Council Directive 2004/108/EC, relating to electromagnetic compatibility, the table below indicates the Maximum
permitted system impedance Z

The data corresponding to DHW tank heater is calculated in combination
with the YUTAKI S80 domestic hot water tank accessory "DHWS(200/260)
S-2.7H2E".
• Check to ensure that existing installation (mains power
switches, circuit breakers, wires, connectors and wire
terminals) already complies with the national and local
regulations.
• The use of the DHW tank heater is disabled as factory
setting. If it is desired to enable the DHW tank heater
operation during normal indoor unit operation, adjust the
DSW4 pin 3 of the PCB1 to the ON position and use the
adequate protections. Refer to the section
switches and RSW switches"
