Above 10°C ambient temperature, the heat pump will operate until 55°C. Configuring
a higher setpoint with an ambient temperature that is higher than the set
equilibrium temperature will prevent the backup heater from assisting. The backup
heater will ONLY assist if you increase the equilibrium temperature [5‑01] to the
required ambient temperature you need to reach the higher setpoint.
