Operating instructions
13
In this operating mode, the Daikin Altherma M ECH
2
O is
switched to Stand-by mode. The frost protection function (see
chap. 3.6.5) is maintained. In order to maintain this function, the
system may not be disconnected from the mains.
All controllers integrated in the RoCon system via the CAN bus
are primarily also switched to the "Standby" operating mode.
Fig. 3-8 Standard display in the "Standby" operating mode
(above the frost limit temperature)
Operating mode Reducing
Reduced heating mode (lower target room temperature) ac-
cording to the target feed temperature set for reducing mode in
the parameter [T-Reduced] (see chap. 3.4.4).
Hot water preparation according to the set target hot water tem-
peratures and switching cycles in the hot water time program
[DHW Program 1] (see chap. 3.4.5).
Heating, Cooling
Heating, cooling mode according to the target room temperature
set in the parameter [T-Room 1 Setpoint] (see chap. 3.4.3).
A connected outside temperature sensor (weather-dependent T-
HS control) or a connected room station also influence the target
feed temperature (prerequisite: parameter [HC Function] = On).
Hot water preparation according to the set target hot water tem-
peratures and switching cycles in the hot water time program
[DHW Program 1] (see chap. 3.4.5).
Operating mode Summer
Hot water preparation according to the set target hot water tem-
peratures and switching cycles in the hot water time program
[DHW Program 1] (see chap. 3.4.5).
All controllers integrated in the RoCon system via the CAN bus
are primarily also switched to the "Summer" operating mode.
Operating mode Automatic 1 (time program)
Automatic heating and setback mode according to the permanent
time programs (see chap. 3.4.7):
– [HC Program 1]
– [DHW Program 1]
Operating mode Automatic 2 (time program)
Automatic heating and setback mode according to the permanent
time programs (see chap. 3.4.7):
– [HC Program 2]
– [DHW Program 2]
If the hot water readiness is in setback mode in the
active operating mode,
a temporary "DHW Re-
heating" can be set with the rotary switch setting
without having to change other standard settings (see
chap. 3.4.6).
Switching contact for external operating mode
switch-over
A potential-free switching contact connected via Daikin
Altherma M ECH
2
O connection J8 at the "EXT" terminals and
wired with a resistor can also be used to switch the operating
mode from an external device (e.g. modem, …).
In this case, the switching contact functionality is dependent on
the parameter [Function BSC]:
– [Function BSC] = 0 (default setting): evaluation of the resist-
ance values (see tab. 3-6)
– [Function BSC] = 1: evaluation as a burner blocking contact.
If the switching contact is closed, the external heat generator
has priority.
Operating mode Resistance Tolerance
Standby < 680 Ω
± 5 %
Heating 1200 Ω
Reducing 1800 Ω
Summer 2700 Ω
Automatic 1 4700 Ω
Automatic 2 8200 Ω
Tab. 3-6 Resistance values for evaluating the EXT signal
The resistances specified in tab. 3-6 function in a toler-
ance field of 5%. Resistances outside this tolerance
field are interpreted as an open input. The heat gener-
ator switches back to the previously active operating
mode.
The input is not considered for resistance values greater than
the value for "Automatic 2".
If several switching contacts are to be connected to the Daikin
Altherma M ECH
2
O (e.g. Smart Grid, room thermostat), the re-
lated functions may have a higher priority than external oper-
ating mode switch-over. The operating mode requested by the
EXT switching contact is then possibly not activated, or is only
activated later.
Besides these operating modes, different temporary heating pro-
grams (see tab. 3-7) are available that are carried out with priority
after activation.

Tab. 3-7 Overview of temporary time programs
If a temporary time program (DHW Install, Party, Away,
Holiday, Vacation, Screed) is started during the se-
lected operating mode, control is carried out primarily
according to the settings for this time program.
