How can I fix a 'Westherm Four' thermostatic rad. valve?

Regardless of the temperature setting of the valve, the radiator is always ON. Rotating the cap makes no difference.

Under the control head is a brass pin - they often get stuck in the fully on position - remove the control head and pull the litle pin up gently with pliers.
