I,ve just fitted two trv,s one upstairs and one down stairs. Upstairs heating is working fine. Downstairs radiators are cold. Any suggestions.

You many need to vent the radiator as it may be full of air and no water. other case could be lock shield valve on other side is not open enough. If that not it you may have an air lock so simply drain down the system
and refill
