Backup heater only operation. No outdoor operation.
Outdoor unit operation is possible if setpoint ≥⁠25°C.
Operation of outdoor unit is possible, but with possible capacity reduction. If the outdoor temperature <⁠–⁠25°C, the outdoor unit will stop. Indoor
unit and backup heater operation will continue.
Pull-down area.
Remark: In restricted power supply mode, the outdoor unit, booster heater, and backup heater can only operate separately.
(*) ERLQ units include special equipment (insulation, heater sheet,…) to ensure proper operation in areas with low ambient temperatures and high
humidity conditions. In such conditions, the ERHQ models may experience problems with severe ice buildup on the air-cooled coil. If such
conditions are expected, the ERLQ must be installed instead. These models contain countermeasures (insulation, heater sheet,…) to prevent
freeze-up.
