Heating thermostat replacement due to broken cover Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

Hi all,
Praying you can help....kids 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.
