Interlink fct Configuration for systems that are operated with 2 different target feed temperatures
(see chap. 3.6.6).
One possible application is e.g. the additional integration of an FWXV-ATV3 in a surface
heating and cooling system.
Prerequisite: 2 room thermostats are connected to Daikin Altherma M ECH
2
O plug con-
nection J16.
Off: Deactivated
On: evaluation of the heating
and cooling switching contacts at plug con-
nection J16 on the RoCon BM1 printed circuit board.
Activation of cooling mode only by switching the operating mode to "Cooling" (see
chap. 3.4.2).
Setting of the parameter [Room thermostat] is no longer evaluated.
a) Open switching contacts: only frost protection active
b) "Heating" and "Automatic 1" / "Automatic 2" operating mode active during the
switching cycles in day mode.
Closed heating
switching contact = IL1:
The system is regulated to the normal target feed temperature as per the
parameter settings in the "HC Configuration" > "Heating" level.
Closed cooling
switching contact = IL2:
The system is regulated to the increased target feed temperature (normal target
feed temperature + value of the parameter [T-Flow CH adj]. Priority if both
switching contacts are closed!
c) "Cooling" operating mode active.
Closed heating
switching contact = IL1:
The system is regulated to the normal target feed temperature as per the
parameter settings in the "HC Configuration" > "Cooling" level.
Closed cooling
switching contact = IL2:
The system is regulated to the reduced target feed temperature (normal target
feed temperature - value of the parameter [T-Flow Cooling adj]. Priority if both
switching contacts are closed!

MF 1 Config Configuration of the multi-function output (230 V, J14 connection):
0: The output is without function.
1: Header pump – The output becomes active as soon as a system heating circuit reports
a heat requirement to the heat generator.
2: Circulation pump – The output is activated either after the time program of the circu-
lation pump or after the time program of the hot water generation, depending on the par-
ametrisation (see chap. 3.4.7).
3: Feeder pump – The output becomes active as soon as a heat requirement is pending
for the direct heating circuit of the heat generator.

Pump dT heating (*) Heating: required temperature difference between return and feed temperature. If a min-
imum temperature difference is required for good heat distribution system operation in
heating mode.

Pump dT cooling (*) Cooling: required temperature difference between return and feed temperature. If a min-
imum temperature difference is required for good heat distribution system operation in
cooling mode.

Pump limit (*) This parameter defines the maximum pump speed. Under normal conditions, the default
setting should NOT be changed. The limitation of the pump speed is skipped if the flow
rate is in the range of the minimum flow rate.
0: No limit
1 - 4: Limitation of the pump speed independent of the operating status.This setting can-
not guarantee heating comfort. The maximum water flow rate is reduced depending on
the setting as follows: 1: 90 %, 2: 75 %, 3: 65 %, 4: 55 %
5 - 8: Limitation of the pump speed if there is no heating or cooling requirement. The max-
imum water flow rate is reduced depending on the setting as follows: 5: 90 %, 6: 75 %,
7: 65 %, 8: 55 %.

Sensor Config
Tamb Config (*) Configuration of the optional outside temperature sensor.
0: no sensor evaluation
1: sensor evaluation activated. To determine the target feed temperature, this sensor is
evaluated and shown on the standard display.

Storage Config Configuration of the hot water generation:
Inactive: No function for hot water generation.
Sensor: Function for hot water generation is activated. A storage temperature sensor is
evaluated for hot water generation (if no storage temperature sensor is connected, an
error message is generated).
Thermostat: Function for hot water generation is activated. A thermostatic switch (On /
Off) is evaluated for hot water preparation, whereby "open terminals" is evaluated as "no
requirement".
