How do I unlock this thermostat?

This clearly needs programming, but before that I need to rid of the display padlock. I am going through my paperwork to find the manual but have tried random combination of the buttons on the panel (in much the same way as I do when resetting the clock on my oven!) with no luck.
This was working when it was installed 2 years ago, but the truth is no haven't used this zoned area and despite having a separate radiator powered with the main heating system the room is today feeling distinctly chilly! My attempt to activate the UFH is a failure
Can anyone help?

Take a clear face-on pic, and do a Google images search. You'll almost certainly find it that way.
Then, 'instructions'!

Easier said than done... The model is HC90-WHT-WIFIThisIsWeird said:Take a clear face-on pic, and do a Google images search. You'll almost certainly find it that way.

Try pressing two right buttons together

Thanks for the effort you put into this @grumbler - tried this w/o success. Am convinced it is a Honeywell but there are umpteen models out there and can I find the darned instructions?! No....No man is worth crawling on this earth.

If it's realy HC90, then it's 'HeatCom Corporation', not Honeywell1

Press and hold the second button from the left for 3 seconds (or maybe slightly longer). That might remove the lock.
Any language construct that forces such insanity in this case should be abandoned without regrets. –

Instructions for the HC90 are here:Section 7.3 says that pressing and holding the return key for 3 seconds activates the lock.It does not mention unlocking, but I'd put money on it being the same process as as locking.......

Do you know if it's WiFi, Rosa? It doesn't appear to be.

What happens if you press - or press-and-hold - the LH 'O' button?
