If the heat is full off or full hot nothing in between and the means of temp regulation is via the monovalve, doesn't that mean the monovalve is working fine? Anyway, I had this problem with my 300D plus clicking sounds in the CCU. I took apart the temp dial to expose the potentiometer and cleaned it with brake clean, checked full range of the pot with an ohmeter to make sure I have full range of continuity, reassembled and no more clicking and I have control over the temp. YMMV
