Junkers Cerapur Midi ZWB 24-1 AR: Connecting PROND Weather Sensor Compatibility & Installation

I warmly welcome,

I replaced the boiler Termet Mini Max for Junkers Cerapur Midi ZWB 24-1 AR , I connected to it a room regulator from the previous one and it works correctly as with the previous boiler.
Junkers Cerapur Midi has one more cube of 2 veins with a thermometer sticker, similar to a weather sensor (regulation of the maximum CH water temperature).
I have a question for you, is it enough to connect to this cube? Weather sensor for PROND controllers you can buy it on the Allegro for PLN 40.
No expense compared to other solutions, but will it even work with this furnace?

Prond weather sensor is a device used to regulate the boiler temperature, taking into account the outside temperature. For example, when the outdoor temperature drops, the controller increases the boiler temperature. When the outdoor temperature increases, the regulator lowers the boiler temperature to previously set values. At this auction you will buy a sensor with a 10-meter cable. It can be connected to the controller located next to the furnace (e.g. Titanic or other Prond controllers equipped with the possibility of connecting a weather sensor). The temperature is set on the regulator next to the boiler, which controls the sensor located outside the building.

The weather sensor must be from Junkers. Others will not work.

Not only that, the room thermostat must also be from junkers to the weather

Midi has so-called simple weather. After connecting the external sensor, the boiler regulates the water temperature of the central heating system in relation to the external temperature. The test method must be selected heating curve and that's it.
A Junkers thermostat is not required.

Don't you screw me up sometimes?
The room regulator can be anything that short-circuits and opens the wires, if open, the stove will only turn on with the anti-freeze program. that's why every stove without a room regulator has a jumper on to start heating and cuts it off with overheating of water such L-3 (my stove is L-3 adjustable from 1 to maybe 9 minutes or even 15 I don't have instructions on hand)
It follows that the output to a thermometer in this furnace is independent of the room regulator, moreover, it is even a separate cube in a different place.
(I don't know if it is a controlled voltage, resistance or short circuit, but it is the third one that falls off.)
The furnace also has the function of cooperating with solariums but I can only see that the adjustable delay in firing the burner on demand for CW.

A compact how does it need orginal?

At the time I was changing, there was no compact yet. Quick verification on the junkers site clearly says that he has built-in weatherclock as well as midi.

Cerapur Midi will work with ON / OFF room thermostats.
It has NO built-in simple weather and connecting an external sensor will not do anything.

Actually.
@bluegin I was wrong. I hope you haven't bought the sensor yet.

Unfortunately, I have already bought it, maybe I will do something with 10 meters of cable and a sensor built into a waterproof forest

The sensor has arrived
I did the test, the sensor can be measured resistance with a multimeter behaves like a diode in one direction does not conduct in the other no.
the cube from the oven hangs on two wires and has a house sticker with a thermometer on the outside.
This cube has a voltage of 3.15V after connecting the sensor to one side (poles), nothing happens.
When connected the other way, the voltage on the cube drops to 0.56V.
After throwing into the fridge the drawer of the -16 deg. C sensor freezer on the cube voltage is 0.60V
as the sensor heats up to 21 ° C, the voltage drops to 0.56V again

The boiler was set at 60 degrees C.
On the boiler itself, I did not notice any changes, the temperature on the boiler did not rise or fall.
the room regulator was still in heating mode (I put it on the windowsill and opened the window)

Well maybe it doesn't work or I don't do something right.

As colleague 12B wrote, the output is inactive (there is no weather) for the Midi ZWB24-1AR boiler, you can only use a simple on-off regulator. Do not try because you will expose the disc to damage.

there are more functions in the service menu 2 than in the manual.
while in menu 1, e.g. there is no automatic venting function, the manual does not have a menu.
this week a neighbor installed such a boiler I will compare the instructions
but with this weather it is a fake ... I just wonder this tension on the ankle from the weather

I have a question. Which wireless room regulator will work with this furnace?
I am asking because I have already returned one that I bought on the Internet. It is true that the regulator connected to the control panel but did not turn off the stove.

Every on / ode controller will work with MIDI ceramics
Salus, Euroster, Auroton, Tech etc.
