Underfloor Heating Screed Dryout - Daikin EBLQ05+07CAV3 Installer's Reference Manual

8 Configuration
INFORMATION
Disinfection function is restarted in case the domestic hot
water temperature drops 5°C below the disinfection target
temperature within the duration time.
INFORMATION
An AH error occurs if you do the following during
disinfection:
▪ Set the user permission level to Installer.
▪ Go to the DHW tank temperature home page (Tank).
▪ Press to interrupt the disinfection.
8.3.3 Heat source settings
Backup heater
Backup heater operation mode: defines when backup heater
operation is enabled or disabled. This setting is only overruled when
backup heating is required during defrost operation or malfunctioning
of the outdoor unit (when [A.5.1.2] is enabled).
# Code
[A.5.1.1] [4‑00] Backup heater operation:
▪ 0: Disabled
▪ 1 (default): Enabled
[A.5.1.3] [4‑07] Defines whether backup heater second
step is:
▪ 1: Allowed
▪ 0: NOT allowed
In this way it is possible to limit the
backup heater capacity.
N/A [5-00] Is backup heater operation allowed
above equilibrium temperature during
space heating operation?
▪ 1: NOT allowed
▪ 0: Allowed
[A.5.1.4] [5‑01] Equilibrium temperature.
Outdoor temperature below which
operation of the backup heater is
allowed.
Range: –15°C~35°C (default: –4°C)
(step: 1°C)
Auto emergency
When the heat pump fails to operate the backup heater can serve as
an emergency heater and either automatically or non-automatically
take over the heat load. When auto emergency is set to Automatic
and a heat pump failure occurs, the backup heater will automatically
take over the heat load. When a heat pump failure occurs and auto
emergency is set to Manual the domestic hot water and space
heating operations will stop and need to be recovered manually. The
user interface will then ask you to confirm whether the backup heater
can take over the heat load or not. When the heat pump fails,
appear on the user interface. If the house is unattended for longer
periods, we recommend that setting [A.5.1.2] Emergency shall be
set to Automatic.
# Code
[A.5.1.2] N/A Defines whether in an emergency
situation the backup heater is allowed to
automatically take over the entire heat
load or whether manual confirmation is
required.
▪ 0: Manual (default)
▪ 1: Automatic

Description
INFORMATION
The auto emergency setting can be set in the menu
structure of the user interface only.
INFORMATION
If a heat pump failure occurs and [A.5.1.2] is set to Manual,
the room frost protection function, the underfloor heating
screed dryout function, and the water pipe antifreeze
function will remain active even if the user does NOT
confirm emergency operation.
Bivalent
Applies only to installations with an auxiliary boiler (alternating
operation, parallel connected). The purpose of this function is to
determine — based on the outdoor temperature (possibility 1) or on
energy prices (possibility 2) — which heating source can/will provide
the space heating, either the outdoor unit or an auxiliary boiler.
The field setting "bivalent operation" applies only to the space
heating operation of the outdoor unit and the permission signal for
the auxiliary boiler.
Possibility 1
The installer can set an equilibrium temperature below which the
boiler will always operate when the electricity prices (High, Medium,
Low) are "0" in the menu structure.
NOTICE
Do NOT use overview settings!
When the "bivalent operation" function is enabled, the outdoor unit
will stop automatically with space heating operation when the
outdoor temperature drops below the "bivalent ON temperature",
and the permission signal for the auxiliary boiler becomes active.
When the bivalent operation function is disabled, space heating
operation by the outdoor unit is possible at all outdoor temperatures
(see operation ranges), and the permission signal for the auxiliary
boiler is ALWAYS deactivated.
▪ [C‑03] Bivalent ON temperature: defines the outdoor temperature
below which the permission signal for the auxiliary boiler will be
active (closed, X8M/3+4 on option box EK2CB07CAV3) and
space heating by the outdoor unit will be stopped.
▪ [C‑04] Bivalent hysteresis: defines the temperature difference
between bivalent ON temperature and bivalent OFF temperature.
