I recently bought a used heatilator ps35. I love the way it heats. Only problem is in order for it to work at all I have to bypass the thermostat...ie i wire the wires together and presto it lights and feeds. If hooked up to the thermostat i get convection blower, but no pellet feed, even when i hit the reset button. I purchased a new honeywell CT30 heat only millivolt thermostat. Still nothing. Any ideas?
