Hi. so my drayton ma1 actuator broke ages ago but i didn't replace it, i just removed it and set the valve manually to CH and did without HW.
All was well until recently when the drayton rts1 thermostat wouldn't click to activate the CH(although occasionally it did when left for a while).so i decided to replace the actuator which was straight forward.
There is a lever on the side which is in the lock position and according to the instructions will release when it receives power.It is currently in the mid position.
So i tested it.with CH on the timer switched to ON the rts1 still doesn't click to activate.The actuator is still locked and in the mid position.
With the HW on the timer switched to ON the boiler kicks in,the actuator remains locked and in the mid position,so i get hot rads and water until the tank thermostat shuts the boiler down.
I'm at a loss.
Thanks in advance.
