Option kit Remote user interface EKRUAHTA
The same controller as supplied with indoor unit
can be mounted parallel or on other location. If
2 controllers are installed, the installer needs
to select 1 master 1 slave.
Not possible to use both user interfaces as a
multi zone application (e.g. one in living room,
other one in the kitchen)

interrupted, the compressor will stop operating,
but there is no chance that the settings will be
lost during longer power shutdowns

Product features zone 2 and zone 3 model
Freeze protection for outdoor unit bottom plate
heater

• A bottom plate heater will be standard in areas
  where low ambient temperatures can occur together
  with high humidity conditions (zone 2 model
  ERRQ), in other countries a bottom plate heater
  is available as an option (zone 3 model ERSQ).
• To protect the outdoor unit against severe ice
  build-up on the air-cooled coil

New on Daikin Altherma HT
The bottom plate heater has no external
thermostat, but is controlled by the PCB of the
indoor unit

• ON/OFF depending on
• Hysteresis 3 lt Ta lt 5
• Unit operation status

6. Summary
31
Applications examples
Space heating DHW heating 1 RC in living room

• No frequent start/stop of the unit and no big
  temperature fluctuations in the room
• Smart logic functionality which controls the
  combined space heating and DHW demand

32
Applications examples
Space heating DHW heating 1 RC in living room,
1RC near the unit
The main remote controller (C1) is installed in
the living room and can access all settings
(master). The second remote controller (C2) can
not access schedule and parameter settings (slave)
33
Applications examples
Space heating DHW heating 1 external RT in
living room, 1RC near the unit
There is only room thermostat on/off control.
There is no smart logic functionality for space
heating, DHW operation is performed according to
the min/max timer operation
Daikin can not guarantee neither good operation
nor reliability of the system, if a non-Daikin
thermostat is used ( NO WARRANTY)
34
Applications examples
Multiple setpoint control
Space 0 Radiators Tsetpoint 65C
Space 1 Fan Coil Units Tsetpoint 45C
Space 2 Under Floor Heating Tsetpoint 35C
If there is a heat demand from space 0, the
leaving water temperature delivered by the Daikin
system is too high
A Temperature reducing device (TRD) is required
for space 1 and 2, to lower the water temperature

TRD
When TRDs are installed, the system can be
configured to use multiple water set point.

• The TRDs are field supply
• Control of the TRDs is not done by the heat
  pump system
• Operation and configuration of the TRDs is the
  responsibility of the installer

Daikin only offers the possibility to have
multiple set points
35
Applications examples
Space heating DHW heating Radiators and UFH,
DHW tank parallel

• 2 space heating setpoints
• 1 DHW setpoint

no 3-way valve
The DHW tank is installed in parallel with the
TRDs. This allows operating the unit in space
heating and DHW heating simultaneously
36
Applications examples
Space heating DHW heating Radiators / FCU /
UFH, DHW tank in a separate circuit

• 3 space heating setpoints
• 1 DHW setpoint b-03

The DHW tank is installed in a separate circuit
of the TRDs. This configuration does not allow
simultaneous DHW heating and space heating
operation.
37
Applications examples
Space heating DHW heating space heating with
an auxiliary boiler (alternating operation)

• Bivalent operation is only possible for space
  heating operation, not for DHW heating operation
• An auxiliary contact decides whether either the
  Daikin unit or the boiler will operate (e.g.
  outdoor thermostat, electricity tariff contact,
  manually operated contact)
