Third time fortunate! Thanks nick to your guide and help. I cured my problem of the heating switching off after about ten seconds via following your manual and the rationale of the wiring diagram. The cord from my room stat went into connection blocks 3 and 4 in my junction field. 3 had a cord coming from the controller (now warmness link) and four had a cord popping out the opposite side to another block (nine), into which became stressed my three port valve. I moved the cord from nine to 4, to now be nine to 3. This closed the circuit and allowed the heating to stay on. I have additionally tested that the cylinder stat turns the hot water off as soon as it reaches the preset temperature.
