Trial Operation and Testing

1. Trial operation and testing

1-1 Measure the supply voltage and make sure that it falls in the specified range.

1-2 Trial operation should be carried out in either cooling or heating mode.

n For heat pump

• In cooling mode, select the lowest programmable temperature; in heating mode, select the highest programmable

temperature.

1) Trial operation may be disabled in either mode depending on the room temperature.

2) After trial operation is complete, set the temperature to a normal level (26°C to 28°C in cooling mode, 20°C to 24°C in

heating mode).

3) For protection, the system disables restart operation for 3 minutes after it is turned off.

mode when the circuit breaker is opened again.
