room stat added?

I have a Baxi 105e instant, I removed the link between terminals 1 & 2 and connected in a danfossTP5 control clock and room stat. The boiler dose not respond at all when the room stat asks for demand and puts a supply on terminal 2. The boiler acts just the same as it did befor the room stat was added to the circuit. The integral clovk control is set to constant and iff I turn up the integral temp control the boiler fires up. However if I turn down the room stat the boiler still operates of the integral stat, as if they were in parrallel
