4 Function
Interlink function
Setting the [Interlink function] parameter = On offers the possibility
that the Daikin Altherma ETS(X/H) two different feed temperature
setpoints are included in the controller.
This applies to both weather-compensated control and control ac-
cording to a fixed feed target temperature (see
One possible application is, for example, the additional integration of
an HP convector in a surface heating and cooling system.
Prerequisite: 2 switching contacts are connected to Daikin Altherma
ETS(X/H) plug connection J16 (e.g. room thermostats).
▪ [Interlink function] parameter = Off: Deactivated
▪ [Interlink function] parameter = On: Evaluation of the heating and
cooling switching contacts at plug connection J16 on the RoCon
BM2C PCB. Activation of cooling mode only by switching the op-
erating mode to [Cooling] (see
thermostat] parameter is no longer evaluated.
▪ Open switching contacts: Only frost protection active
▪ [Heating] or [Automatic 1] / [Automatic 2] operating mode active
during daytime switching cycles.
▪ Closed switching contact Heating = IL1
▪ It is controlled to the normal feed target temperature according
to the parameter settings for [Heating].
▪ Closed switching contact Cooling = IL2
▪ It is controlled to the increased feed target temperature (normal
feed target temperature + value of the [Interlink temperature in-
crease ] parameter). Priority if both switching contacts are
closed!
▪ [Cooling] operating mode active.
▪ Closed switching contact Heating = IL1
▪ It is controlled to the normal feed target temperature according
to the parameter settings in level [Heating circuit config.] >
[Cooling].
▪ Closed switching contact Cooling = IL2
▪ The system is regulated to the reduced feed target temperature
(normal feed target temperature value of the [Interlink temperat-
ure increase ] parameter. Priority if both switching contacts are
closed!

Intelligent storage tank management

[→ Main menu → Settings → ISM]
If the storage temperatures are high enough, the energy in the stor-
age tank can be used for room heating. This can either increase
comfort ([Continuous heating] function) or make it possible to use
energy from an external heat source, e.g. solar, when heating is re-
quired ([Heating support (HZU)] function).
Continuous heating
This function enables uninterrupted heating, even when the evapor-
ator is being defrosted. This enables high comfort to be guaranteed,
even with rapidly reacting heating systems (e.g. convectors).
Heating support (HZU)
If the Heating support function ([Heating support (HZU)] parameter =
On) is activated, the energy in the Daikin Altherma ETS(X/H)'s integ-
rated storage tank is used to undertake the heating function. If the
storage temperature is sufficiently high, the burner remains inactive.
The minimum value (T ) is calculated as follows: T

target] + [Heating support hysteresis] parameter.

formation parameter + 1 K
If the switch-on condition is fulfilled, heat is taken from the storage
tank and this is used to supply the heating system.
Switch-off condition:
Tdhw < T or Tdhw < [Feed temperature, target] parameter (see
HZUmin
Chap. 4.5.3)
If the switch-off condition is fulfilled, the heating support from the hot
water storage tank is set and the burner takes over the heating oper-
ation.
The [Heating support power] parameter limits the maximum power
that can be taken. The [Heating support max. temp.] parameter limits
the maximum temperature that can enter the heating system.
Further explanations and possible settings for the parameters in this
menu can be found in Chap. 7.5.5.

Configuration

[→ Main menu → Configuration]
This menu can be used to optimally adapt the operating characterist-
ics of the system to the system structure and the needs of the users.
Additional programs facilitate commissioning. Depending on the ac-
cess authorisation (user or expert), different parameters are avail-
able.

Access privileges (technician code)

[→ Main menu → Configuration → Access]
Certain functions and parameters in the controller are restricted by
access rights and are not visible to the user. To gain access to it, the
specialist code must be entered.
Fig. 4-1 Setting the access code
Example: Set code 3090 (example only, this is not a valid access
code) [→ Main menu → Configuration → Access]:
1 Turn the rotary button clockwise until the first input field is dis-
played in blue.
2 Briefly press the rotary button to confirm ("OK").
è The first input field flashes blue.
3 Turn the rotary button clockwise until 3 is displayed.
4 Briefly press the rotary button to confirm ("OK").
è The second input field is displayed in blue.
5 Turn the rotary button clockwise until the third input field is dis-
played in blue.
6 Briefly press the rotary button to confirm ("OK").
è The third input field flashes blue.
7 Turn the rotary button clockwise until 9 is displayed.
