NOTE
The data corresponding to DHW tank heater is calculated in combination with the domestic hot water tank accessory "DHWT‑(200/300)S‑3.0H2E".
• 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.
