Delta Dore Euro-Tybox 4 Radio X2D 868

[RSDonovan]

I have an apartment with the above radio controlled thermostat on a radiator which is accessed by a remote control.

Typically, I can find the user manual for every appliance but this one, and trying to guess what all the functions do is driving me crazy!

I have searched the Internet for a manual without success, I cannot find this exact model although there are some very similar but having buttons and usually a “mode selector “ wheel which mine lacks!

I’m told this is a very sophisticated device but without assistance it is as good as useless to me!

Would appreciate any help,

Thanks in advance
