Configuration Wizard: Main Zone - Daikin ETSHB16P50EF Installation Manual

INFORMATION
Energy data calculations of the unit will only be correct for
settings of [6-03] and [6-04] which fit the actually installed
backup heater capacity. Example: For a backup heater
with nominal capacity of 6 kW, the first step (2kW) and the
second step (4kW) correctly sum up to 6 kW.
Capacity step 1
# Code
[9.3.4] [6‑03] ▪ The capacity of the first step of the
backup heater at nominal voltage.
Additional capacity step 2
# Code
[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.
Maximum capacity
# Code
[9.3.9] [4‑07] ▪ Maximum capacity that should be
delivered by the backup heater.
▪ Range: 1 kW~3 kW, Step 1 kW

Configuration wizard: Main zone

The most important settings for the main leaving water zone can be
set here.
Emitter type
Heating up or cooling down the main zone can take longer. This
depends on:
▪ The water volume of the system
▪ The heater emitter type of the main zone
The setting Emitter type can compensate for a slow or a quick
heating/cooling system during the heat up/cool down cycle. In room
thermostat control, Emitter
modulation of the desired leaving water temperature, and the
possibility for usage of the automatic cooling/heating changeover
based on the indoor ambient temperature.
It is important to set Emitter type correctly and in accordance with
your system layout. The target delta T for the main zone depends on
it.
# Code
[2.7] [2‑0C] ▪ 0: Underfloor heating
▪ 1: Fancoil unit
▪ 2: Radiator
The setting of the emitter type has an influence on the space heating
setpoint range and the target delta T in heating as follows:
Description Space heating
setpoint range
0: Underfloor
Maximum 55°C

1: Fancoil unit Maximum 55°C
2: Radiator Maximum 70°C

NOTICE
Average emitter temperature
temperature – (Delta T)/2
This means that for a same leaving water temperature
setpoint, the average emitter temperature of radiators is
lower than that of underfloor heating because of a bigger
delta T.
Example radiators: 40–10/2=35°C
Example underfloor heating: 40–5/2=37.5°C
To compensate, you can:
▪ Increase the weather-dependent
temperatures [2.5].
▪ Enable leaving water temperature modulation and
increase the maximum modulation [2.C].
Control
Define how the operation of the unit is controlled.
Control
Leaving water
Unit operation is decided based on the leaving
water temperature regardless the actual room
temperature and/or heating or cooling demand
of the room.
External room Unit operation is decided by the external
thermostat thermostat or equivalent (e.g. heat pump
convector).
Room thermostat Unit operation is decided based on the ambient
temperature of the dedicated Human Comfort
Interface (BRC1HHDA used as room
thermostat).

Setpoint mode
Define the setpoint mode:
▪ Fixed: the desired leaving water temperature does not depend on
the outdoor ambient temperature.
▪ In WD heating, fixed cooling mode, the desired leaving water
temperature:
▪ depends on the outdoor ambient temperature for heating
▪ does NOT depend on the outdoor ambient temperature for
cooling
▪ In Weather dependent mode, the desired leaving water
temperature depends on the outdoor ambient temperature.
# Code
[2.4] N/A Setpoint mode:
▪ Fixed
▪ WD heating, fixed cooling
▪ Weather dependent
When weather dependent operation is active, low outdoor
temperatures will result in warmer water and vice versa. During
weather dependent operation, the user can shift the water
temperature up or down by a maximum of 10°C.
Schedule
Indicates if the desired leaving water temperature is according to a
schedule. Influence of the LWT setpoint mode [2.4] is as follows:
▪ In Fixed LWT setpoint mode, the scheduled actions consist of
desired leaving water temperatures, either preset or custom.
