Question about DeLonghi Heating & Cooling
I bought a delonghi HVF 3031 fan heater yeterday.according to manual , in order to adjust thermostat, i turned thermostat knob to maximum position then I selected the power level. At desire temperature , i gently turned thermostat anti -clockwise till the click sound heared and fan turned off. The problem is it doesnt stArt automatically when temperature drops. I would be grateful if you can help with this issue.
Try this. Do as you already did above, but this time turn the thermostat slightly clockwise till it comes on again, and leave it at that setting for a while. Does it control now?

the wick could be dirty and or burnt not allowing for the know to be moved to the off position, I would suggest cleaning the wick or replacing before doing anything else.

Make sure the cover is on the furnance and secured properly, the next thing to check is the switch located on the side of the furnance it could have been accidently move to the off postion. If these two check out you will need to replace the thermostat.

The pressure switch is located in the front header, behind the
upper side jacket panel, above the water connections. When
required, the pressure switch can be reset with the following
1. Clean filter and skimmer.
2. Start filter pump.
3. Set digital thermostat to highest setting.
4. Turn the adjustment knob on the pressure switch clockwise
until the combustion air fan in the front control panel turns
off. Fan will not turn off if system pressure exceeds 5 PSI.
5. Slowly turn the adjustment knob counter-clockwise until the
combustion air fan turns on. Turn knob an additional ¼ turn
6. Turn filter pump off and on several times. The heater should
shut down immediately when the pump stops.
7. If the heater does not shut down immediately as the filter
pump stops, repeat steps 4, 5 and 6 until proper operation
8. Reset thermostat to desired temperature setting.
If after doing all of the above you still have the problem.... you can remove the switch and check for debris in the water passages. If you find debris remove it, reinstall the switch and repeat steps above.
- Still have the problem... Replace the switch.
