Operation
Operating mode Automatic 2 (Timer programme)
Automatic heating and economy mode in accordance with the
permanent timer programmes (see section 3.4.7):
– [HC Program 2]
– [DHW Program 2]
If, in the active operating mode, the hot water gener-
ation is in setback, you can use the rotary switch
to set temporary
"DHW Reheating"
without having to
change any other standard settings (see section 3.4.6).
Switching contact for external operating mode
switching
Likewise, the operating mode (see tab. 3-6) can be
switched from an external device (e.g. modem, etc.) via
a potential-free switching contact which is connected to
a resistor and to the terminals "EXT" at the J8 port on
the Daikin Altherma EHS(X/H).

Tab. 3-6 Resistance values for the evaluation of the EXT signal
The resistances specified in tab. 3-6 work at a toler-
ance range of 5 %. Resistances outside of this toler-
ance ranges are interpreted as open input. The heat
generator resets to the previously active operation
mode.
At resistance values higher than the value for
"Automatic 2", the input is not considered.
If several switching contacts are to be connected to the
Daikin Altherma EHS(X/H) (e.g. SMART GRID, Room
thermostat), the associated functions can have a higher
priority than the external operating mode switching. The
operating mode requested by the EXT switching
contact might then not be activated or may be activated
later.
In addition to these operating modes there are various different
temporary heating programmes available (see tab. 3-7), which
run according to priority after they have been activated.

Tab. 3-7 Overview of temporary timer programmes
If a temporary timer programme (DHW Install, Party,
Away, Holiday, Vacation, Screed) is started during the
selected operating mode, the regulation will take place
with preference according to the settings of this timer
programme.
3.4.3 Temperature setting Daytime room temperature
The set room temperatures for room heating during the day are
determined in the rotary switch setting
.
●

position.
An overview is displayed.
The end figures of the parameter designations (1 - 3)
within this rotary switch setting designate the associ-
ation with each individual cycle of the timer programme.

Change has been accepted. Jump back to previous dis-
play.
More detailed explanations and possible setting values for this rotary switch setting
can be seen in chapter 5.5.
3.4.4 Temperature setting Economy mode
The set room temperatures for room heating in economy mode
are determined in the rotary switch setting
.
●
Place the rotary switch in the
"Set Temp Night"
position.
An overview is displayed.
●
Select the parameter to be set with the rotary switch.
●
Confirm the changes with a brief push of the rotary switch.
– [T-Reduced]: Set value for "Reducing" operating mode or
setback by a permanent timer programme.
– [T-Absence]: Set value for temporary heating / cooling
programmes ("Away" and "Vacation").
Settings are displayed.
●
