Termet Silver 25kW Boiler: Wireless VT292 Driver, Cycling & Modulation Settings Explained

Hello, I have a question about the Silver 25kw 2f termet boiler.
Well. It works with the wireless vt292 driver. Is it normal that during heating, when the desired temperature is to be reached, the boiler works in cycles. I measured with a stopwatch and it is exactly 1.47 (a minute and 47 seconds) the boiler is running, and it is still off for 2 minutes and 5 seconds. Is it normal ? Such jumps all the time?

Besides, I have a question, where do I set the modulations when the boiler is to be controlled by a room controller?
With this plus and minus on the boiler, the range from 40 to 80 degrees is modulation?
How much should it be set?

Modulation ranges from min power to the power set by the service technician. You set the temperature for the radiators that is to leave the boiler. If it is too low, e.g. 40 degrees C, the boiler is just a moment and heats up the entire installation to this temperature, thus the boiler turns off and waits for the temperature to drop below the set temperature. Set for example 55 degrees C and watch ....
Everything in the manual is written in a very good way ...

set on the boiler maximum, i.e. 80.

the boiler runs every 2 minutes ...

which parameter is responsible for this?

as if I have a service manual for this boiler

As there was a service technician on a zero start, he should explain everything to you and set it up. I do not recommend digging alone, because it is easy to break - contrary to the opinion of amateur users on the forum. But they are not the service technicians ...
Set to 55 degrees. Where the thermostatic head temperature regulator is set to max.

Call termete service to swiebodzice if you have any questions or to your service technician !!

Please tell me one more thing, I disconnected the regulator, and I want the boiler to work without it, but the boiler does not respond to manual commands, it waits for a signal from the regulator. even though the regulator is disconnected from the boiler, and the boiler is disconnected from the contact and connected again to reset - but is this the correct reset? because the boiler, as I mentioned, does not want to switch from listening to the regulator (wireless) to listening to manual commands (buttons on the boiler)

ok, I know why he did not want to listen to the manual settings again, I did not put the jumper back after unplugging the regulator.
a boiler without a regulator works properly, frequent disconnection can be seen as the regulator's fault ...

Usually there is a bridge on the boiler in the place where the ON-OFF regulator is connected, because this bridge simulates a continuous 24-hour heating signal and then the boiler should react to manual settings on the boiler.
Read the manual of this boiler to see if the jumper is there at the factory.

When you do changes with your head, there is nothing to spoil. You only need to have a technical sense, and not everyone has it. It is worth knowing what a given option is for, i.e. it would be advisable to know the basics and read the service manual, and not try at random. In addition, it is worth saving the "factory" values, so that you can return to the starting point if the change does not bring the desired effect.
Unfortunately, you need to have predispositions for each activity, so I think that not everyone can be a driver, although some think that everyone can have a license, all you need to do is take the course, pass the exam and it's ready. The same applies to rummaging in equipment, not everyone is predisposed to it, and then it can do more harm than good.

If you have the original Termet ST-292 regulator, contact the manufacturer, maybe this regulator is damaged, because it is not normal to turn the boiler on for 1: 47min.
But remember that the boiler turns off:
- after receiving a signal from the HEATING STOP controller
- after reaching the set temperature of the heating water.
It may be that the temperature with the regulator was set too low, and in your installation the boiler quickly reached this temperature, which is possible with closed thermostatic heads. Therefore, it is recommended that at least 1 radiator be without a head, so that a constant flow of heating water is guaranteed. The more such heaters, the better, but then the risk of overheating these rooms increases.

I set the temperature max. On the boiler. to these measurements. The controller was also set much higher than in the room.

Assuming that the boiler is OK and none of the sensors blocked the burner, the regulator seems to be stiff. Unless it has a strange algorithm for switching on the heating and hence such equal cycles 1: 47min.
Ask the manufacturer, it will probably be faster and more reliable.
