Heating thermostat replacement due to broken cover

Postby doodles1980 » Fri Jan 22, 2021 1:26 pm

Hi all,
Praying you can have broke the cover off our central heating room thermostat.

I've got a BHT-002 to replace it and bit confused with the wiring....the wire colours I have are RED, YELLOW, GREEN, BLUE.

Can anyone help with where these wires go on the screenshot of the new unit?.

Thanks in advance for your help :-)

Colours of the wires means nothing, need to look at the connections of old thermostat.
