My heater is plugged into a thermostat that I have set at around 65 degrees my garage is appox. 30 degrees. When the heater is cold and I first plug it in it runs good after the thermostat is satisfied and the heater shuts off the temp. of course drops to where the thermostat again fires up the heater ( which is still warn ) now the heater will run blowing out lots of smoke but not fire up for anywhere between 10 secs. to the point where I have to manually unplug it. The next day or when the heater has totally cooled its initial start is fine then the problem starts all over. Any ideas ? The heater is a Ready Heater Pro 150,000 btu Thanks, Mike

Most T-Stats have a On / Auto on a forced air system. On means the fan will run all the time even if it is not calling for heat. Auto only runs when calling for heat. Does the fan turn off in the auto mode at all? To test it...BE SURE THE FAN IS IN THE AUTO MODE ON THE T-STAT... Turn the thermostat all the way down and keep it there for appox 15 mins. If it is wired properly and the fan limit is set properly the fan should turn off. If it doesn't it is not the thermostat were the problem lies.
Most forced air units have a fan / high limit switch. There is a setting on the switch for the fan to turn on and a setting for the fan to turn off or it has a setting and a differental switch for it to turn off/on. Example - the fan comes on when the temp in the heat exchanger reaches 110 degrees F and will shut down at 95 degrees F after the thermostat is satified...this would hav a differental of 15 degrees F. It may be set to low and the fan continues to run long after all of the heat has been removed from the heat exchanger. This in turn will cause cool air to be coming out of the registers.
Many recommend you plug the heater in and turn it on in a well-ventilated room (like a garage) for the few hours of use. If you are using the heater to warm a room, plug it in with the thermostat set to maximum and set the power selector to 3 until the room reaches the desired temperature. Then rotate the thermostat clockwise until you hear a click. You can set the power level to 1 or 2 to conserve energy while maintaining the current temperature settings.
If you are trying to avoid frozen pipes in an area, plug in the heater and set the power selector to 3 and thermostat to *.
Always remember to keep anything flammable away from the heater (loose drapes etc.) There is an overheating protection circuit built into the unit. To reset it, you need to call the DeLonghi service center.
If it's operating properly, is T-Stat controlled and is properly vented to the outside, it should be safe to operate all night. I suggest that you set the Wall Thermostat no higher than 50 degrees, though.
On and off is determined by what temperature you set each program for. Example: 6 am - 70 degrees, 8 am - 65 degree, 4 pm - 72 degrees, 11 pm - 65 degrees. You can set the thermostat to fit your schedule and temperature preferences. Good luck.
The thermostat will turn your furnace on and off to satisfy the temperature setting at the location where the thermostat is located. If you move the thermostat to the first floor and set the thermostat at say seventy, it should keep the furnace on until the temperature near the thermostat hits seventy degrees.
These heaters are the same as the marley heater, the element never gets red hot. the unit is set up so the fan kicks on after the element has heated to a certain temp and turns off after the element has cooled. It is common for these heater fans to cycle on and off quite often untill the air temp reaches about 55 degrees and then will operate normaly. If the fan still cycles too often you may have to replace the fan control and high limit switch. These are not very expensive and easy to replace yourself. they arte usualy attached to the back of the element with clips. The luke warm air is what these units put out. I have an equivelent to the dayton G73 and it heats a 24' X 30' garrage all winter in central Minnesota.
The thermostat may not be made to go lower than 50 degrees or so. A new one that can may need to be substituted. Go to the local appliance parts supplier. remove the old one and tell them what range you need.
