Just had one of these controllers for repair. Happy to have found the forum. I removed the relays easily with a low temp solder called chipquik, it melts are 58 degrees. Heat the relay pins and flood the connection with chipquik. once you have done the four connections, reheat them and the relay will drop right out. Testing the relays, one was definitely faulty - would not actuate. Have order spares from RS components, @AndyO
