TURBO Mode
  • In case of urgent demand on more powerful heating capacity output, there is a TURBO mode can be selected on LCD controller panel.
  • When TURBO mode is activated, the control system will increase the working frequency of compressor to an upper limit, the heat pump gives out maximum output.
  • TURBO mode is recommended for temporary use in extreme cold days or at a situation that need more powerful heating.
  • Here is a table shows the estimated outputs for reference.
