A friend has a Honeywell T6360 roomstat. On turning the knob to say 20°C to call for heat, heating starts but doesn't satisfy the stat till way too high, at least 25°C. I found the neutral to the accelerator hadn't been connected, wired that up and expected a cure, but not noticeably better. I checked the resistance of the accelerator, about 330000 ohm, which means it outputs < 0.2 watt. Gut feeling is that's too low. Anybody know what the resistance should be, or any other comments? Appreciate any help.
