Test the stat using a multimeter. If ok it is the wiring.
If you have 2 motorised valves it should be wired permanent live - frost stat - pipe stat - orange of the valves.
Mid position valve, perm live - frost stat - pipe stat - white of valve.
No valves, perm live - frost stat - pipe stat - switched live.

Frost stat should be set to around 5 deg and pipe stat fitted on the return set to around 25 deg.
