timer wiring

Hello I current have installed a honeywell st9100c timer as per the image with the wires. We are in the process of installing a Drayton wiser timer and the wiring in the unit needs to be as per the wiring diagram Please can someone tell me which wires go where as per the wiring diagram...

It seems when the timer was re-fitted something has gone wrong. The symptoms are: Heating only – works OK Water only – works OK However, when you want water and heating together.........the timer seems to go mad. Switching on/off multiple times.....clicking noises etc. Can anyone...
