Parameter settings
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 HP convector in a surface
heating and cooling system.
Prerequisite: 2 room thermostats are connected to ROTEX HPSU monobloc compact
plug connection 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 tempe 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.

Air Purge
Activation of automatic ventilation of the ROTEX HPSU monobloc compact and the con-
nected heating circuit (see chap. 3.6.10).

PWM Config
Emitter type
System reaction time: depending on the water volume in the system and the heat ex-
changer type, heating or cooling a room may take more time. This setting can compen-
sate for a slow or fast heating/cooling system by adapting the device's output during the
heating/cooling cycle.
0: fast. Example: lower water volume and convectors.
1: slow. Example: higher water volume, floor heating circuits.

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".
