INFORMATION
Only for systems with integrated domestic hot water tank: If the storage
temperature setpoint is higher than 50°C, Daikin recommends NOT to disable the
backup heater second step because it will have a big impact on the required time for
the unit to heat up the domestic hot water tank.
Capacity step 1
# Code Description
[9.3.4] [6‑03] ▪ The capacity of the first step of the backup
heater at nominal voltage.
Additional capacity step 2
# Code Description
[9.3.5] [6‑04] ▪ The capacity difference between the second
and first step of the backup heater at nominal
voltage. Nominal value depends on backup
heater configuration.
Equilibrium
# Code Description
[9.3.6] [5-00] Equilibrium: Deactivate backup heater (or
external backup heat source in case of a bivalent
system) above the equilibrium temperature for
space heating?
▪ 0: No
▪ 1: Yes
[9.3.7] [5-01] Equilibrium temperature: Outdoor
temperature below which operation of the
backup heater (or external backup heat source in
case of a bivalent system) is allowed.
Range: –15°C~35°C
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 Description
[9.3.8] [4‑00] Backup heater operation:
▪ 0: Restricted
▪ 1: Allowed
▪ 2: Only DHW: Backup heater operation is
enabled for domestic hot water and disabled
for space heating.
