Equilibrium
# Code
[9.3.6] [5-00]
[9.3.7] [5-01]
INFORMATION
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.
Operation
# Code
[9.3.8] [4‑00]
INFORMATION
Only for systems with integrated domestic hot water tank: If backup heater
operation during space heating needs to be limited but can be allowed for domestic
hot water operation, then set [4‑00] to 2.
Emergency
When the heat pump fails to operate, the backup heater can serve as an
emergency heater. It then takes over the heat load either automatically or by
manual interaction.
▪ When Emergency is set to Automatic and a heat pump failure occurs, the
backup heater automatically takes over the domestic hot water production and
space heating.
Description
▪ The capacity difference between the second
and first step of the backup heater at nominal
voltage. Nominal value depends on backup
heater configuration.
Description
