Special tank: standard tank + passivated + service opening
TBC
Passivated tank: requirement for Danmark
Service hole: requirement for Switzerland and Germany
Cleaning opening of 120 mm at the lowest third part of the tank
Stainless steels are naturally corrosion resistant due to the presence of a very thin, continuous, transparent surface layer, or film, that forms on clean surfaces when exposed to the atmosphere or certain oxidizing conditions. Passivating the surface of the stainless steel in an acid mixture containing oxidizing agents improves and enhances the formation of this corrosion resistant layer.
Why not passivated on all models? Price issue + ecological impact (H2SO4)

20. Product features: DHW tank
Tank performance: heat-up time (calculations)
Size of the coil: length of 23m, surface area of 1,56m², internal coil volume of 7,5L
Calculation example: ERSQ016AAV1 with EKHTS200 tank
Up to a DHW temperature of 70°C, the part load capacity of the heat pump can still be exchanged to the DHW with the 1,56m² coil

28. 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

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
No smart logic functionality for space heating
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 = 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
UFH
65°C
35°C
30°C
A Temperature reducing device (TRD) is required for space 1 and 2, to lower the water temperature
TRD
When TRD’s are installed, the system can be configured to use multiple water set point.
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

35. Applications examples
Space heating & DHW heating: Radiators and UFH, DHW tank parallel
2 space heating setpoints
1 DHW setpoint
No smart logic functionality for space heating
no 3-way valve
The DHW tank is installed in parallel with the TRD’s. 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]
No smart logic functionality for space heating
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.

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)
