Different possibilities to produce DHW

Reheat operation: has always priority above space heating

Storage operation - automatic operation (night and/or day timer)- manual operation

Storage operation has priority above space heating, taking in account:- min/max running timers- smart logic function

Disinfection operation: has always priority above space heating

Product features: User interface

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.

User interface is mounted separately from indoor unit

User interface can be used as a modulating room thermostat

Optimized efficiency due to feedback of room temperature

Optimized changeover from DHW heating to space heating

Option kit: Remote user interface EKRUAHTA

Not possible to use both user interfaces as a multi zone application (e.g. one in living room, other one in the kitchen)

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

Internal use only


Space heating & DHW heating: 1 RC in living room

Applications examples

- 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

32Apr 11, 2023

Internal use only



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)

33Apr 11, 2023

Internal use only



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)

34Apr 11, 2023

Internal use only



Multiple setpoint control

Space 0: Radiators

Tsetpoint = 65°C

Space 1: Fan Coil Units

Tsetpoint = 45°C

Space 2: Under Floor Heating

Tsetpoint = 35°C

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

- The TRD’s are field supply

- Control of the TRD’s is not done by the heat pump system

- Operation and configuration of the TRD’s is the responsibility of the installer

Daikin only offers the possibility to have multiple set points

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

Space heating & DHW heating: Radiators and UFH, DHW tank parallel

The DHW tank is installed in parallel with the TRD’s. This allows operating the unit in space heating and DHW heating simultaneously

- 2 space heating setpoints

- 1 DHW setpoint

no 3-way valve

36Apr 11, 2023

Internal use only



Space heating & DHW heating: Radiators / FCU / UFH, DHW tank in a separate circuit

The DHW tank is installed in a separate circuit of the TRD’s. This configuration does not allow simultaneous DHW heating and space heating operation.

- 3 space heating setpoints

- 1 DHW setpoint [b-03]

37Apr 11, 2023

Internal use only



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)
