    I have a similar problem.  I just purchased a Honeywell 709 radiator heater and after about 1 day of use the heater just shut off on its own (I did not touch the timer button).  After cooling down I pushed the start button and the heater started up again as if nothing was wrong.

    Also, when I first started up the heater (with the thermostadt set to 74) it continued to heat up until the digital thermometer read 86.  I turned it off and then back on again, and it then seemed to work properly.

    Heater is set on the low power (600w) setting and located in a small to medium sized bedroom.

Do not touch the timer, once you do, it activates it. Set the temp. and leave the timer alone, unless you want it to shut off at a given time, 1 hr. and up. Once the timer shuts off you will have to start it manually.

Model hz709 manual

Was there any physical damage to the heater when it fell over?

The HZ-709 has safety features that might prevent its subsequent operation.
1 - It has a tip over switch but the heater should operate normally when it's upright again.
2 - A thermal cut-off fuse will permanently shut down the heater should it operate at a higher than normal temperature. Was it operating when it fell over, or could it have overheated?

If it's none of those, try contacting the manufacturer Kaz directly by email, Facebook, Twitter, etc. as the HZ-709 has a 3-year warranty.

How do we operate and turn on it i have no manual

The left button under the temperature display lets you toggle between the heat output (high, medium and low) settings. Press the left or right side of the buttons. The center button sets the timer; press the left side of the button repeatedly to increase the run time. Press the right side to lower the length of time before the heater shuts off. The right hand button sets the desired final temp. Again it's an up/down toggle on the left and right sides of the button. Once you get to the desired temperature (in 1 degree increments), the display will return to showing the current temperature three seconds after you release the button.

Honeywell HZ-709 oil filled radiator heater-all controlls work but no heat produced. Possible reason?? Thanks

There is a bottom element and a top element so the elements could be dead.

More likey, there could be no power coming from the wall - there are switches on the front that need to light up or the thermostat could be set to off.

How do I program my Honeywell HZ-709 radiator heater

Is there a seperate control for the timer and temp? If so, turn the temp off first and then the timer.I think they need each other for safety.
