De Dietrich MPX 20/24 MI COMPACT can't turn heating off #95

Open mementoars opened 3 days ago

mementoars commented 3 days ago

Hello everyone,

I have a De Dietrich MPX 20/24 MI COMPACT successfully connected to a D1 mini 32+diyless master opentherm shield. Version : 1.4.5 Apartment: attic Indoor sensor: LYWSD03MMC External sensor: DS18B20 Equitherm: enabled (but the coefficients are not adjusted correctly yet).

Boiler shows as a Baxi Luna Duo-Tec image

The controller is connected to home assistant and displays the following: Screenshot

Issue No1: I can't turn the heating off.

Combinations that didn’t fix the problem: image

issue No2: The circulator pump doesn’t stop. Even if I set the desired room temperature to the lowest value (5°C), the circulator pump keeps running and the burner runs periodically to maintain the set temperature. Is this normal?

Note: when Summer/winter mode is enabled in Opentherm settings the heating and flame turn off)

thank you in advance

Hi, Set parameter P67=0 in the boiler service menu.
