Pump anti-lock program, like Grundfos Alpha summer mode

[SMHRambo]

Hi,
I am looking for a way to run the heating circuit pump every few days during summer time.

The pump is connected to a MM50.
When I try to change the value of the pump, nothing happens.
Only when I adjust the target temperature does the pump come on, but unfortunately so does the burner.

Does anyone have any ideas on how to implement this, without switching to the winter/heating mode?

If you can manage this manual with the thermostat, maybe by entering test mode, you can log the steps and then use these commands with ems-esp.
I guess sending only pump command to the mixer (0x2E1, offset 2) will be overwritten by thermostat and has no effect.

@SMHRambo Hi! Are you sure that your device has no such feature by default? My Bosch boiler has it onboard

I have a Buderus Junotherm S315T from 1991 and have since installed a new control unit. This is a Buderus MC/BC10 with RC310 and MM50. The Buderus MC/BC10 has been around for almost 20 years (2004) and unfortunately does not have this function, even if an RC310 is installed, such a function is unfortunately not available.
According to the last manual I found, the pump kick function is only mentioned from BC25 onwards.

It may be that the function exists but is not explicitly listed.
However, the Buderus Logamatic 2107 manual from 2001 mentions the pump kick function.
This is supposed to be activated every Wednesday at 12 noon.
But I cannot find any evidence in my InfluxDB that the pump was active.

I played around with the date and time.
Unfortunately, there was no pump activity at 12 noon.
