Radiator Thermostat – compact vs standard - whisper mode in bedroom?

[valchazzz]

Hello! I try to choose between two thermostats:
1. Radiator Thermostat –compact: HmIP-eTRV-C

2. Radiator Thermostat - standard: HmIP-eTRV-2

I am interested in quiet operation in the bedroom.
Has anyone used both thermostats and compared their noise levels?

I'm thinking of buying the Compact version: HmIP-eTRV-C because it's smaller. But since the model is new and there are no comments about it, I'm afraid it's not louder than the Standard version: the HmIP-eTRV-2.

Thanks a lot for the advice!

You are afraid that it is, or that it is not louder ?

Throw into google translate to read in english. According to that doc, the C version has whisper mode operation, so it could be as quiet as the standard model.

I am right now sleeping beside a HmIP-eTRV-B which i can hear when it is moving, but i kinda find it soothing

eTRV-C-2 has "whisper" mode. It is definitely quieter than "normal" mode.
