Did anyone else experience a 5 degree difference between heater temperature and thermometer? Anyway to collaborate?

yes, my 200 watt is running about 6 F too high and my 300 watt is running about 11 F too high...however they do seem to hold steady once you compensate. And I do seem to have to recheck/recalibrate for the summer months. however there are so few heaters available with an exterior control i figured i'll just put up with this until something better comes along.

There may be a few degree difference between heater and display. If so just clean off heater and node of algae or anything. Then replace. Make sure node has proper placement away from heater as well. Best to have heater vertical and in middle of tank as well.

I've noticed about a 2 degree (F) difference. I just take an average of three thermometers.

I am constaintly in quest for the perfect heater . I have two of these in my 55 gal tank. So far they have been very accurate .

I've found it to be fairly accurate. I have an apex controller, and it's roughly a degree or so off.

Can't help you Ely. My order was supposed to arrive a week ago & I'm still waiting for it. Sorry.

yes, after awhile, the sensor in the temp probe goes bad. It reads the water temperature at lower than it really is and thus the heater overheats. You can adjust downward the temperature to compensate, BUT THE SETTING RESETS TO 79 F EVERY TIME THERE IS A POWER FAILURE so you could end up overheating your tank anyway. Avoid. Right now, 79F setting for me = 89F actual water temperature!

I would be wary of the accuracy, there are "dead spots". I ordered two of these and both of them had a "dead zone" of about 6 degrees (from 76°F-82°F) where it would show it was 76° until it suddenly spiked to 82°.

I put a thermometer in the refrigerator to monitor the temp. It will take several trials to calibrate the dial on the unit. But after you find the correct temperature it will keep that accurately +/-5 degrees.

Yes; it shows the setpoint while you hold an adjustment button, but after you release the +/- button it reverts to showing the actual temperature (of the heater -- the tip temperature lags a little as it does on any station).

You're really asking me to be clairvoyant here . . . but the is a simple way for you to check the internal temperature of your unit. Place an oven proof thermometer on the lower rack position, turn it so you can read it through the bowl, and see if it reads within 5 or 10 degrees of your dial temperature setting. If it is reading too low, then you probably have a malfunctioning unit or you house current is inadequate at the plug. That's the best I can do from afar . . . .

I have noticed it being 5 degrees off from a thermostat 4 feet away, so I had to replace that one with an identical model.

I was wondering the same thing. i bought FIVE of them, and they are all different. For example temp 72 72.5 73 72.8 or 74.2 similar within 8% on humidity, which to me is quite a difference. I let them sit in the same room for five days and they did get a little closer, within 5% of each other.

I did not calibrate it except to test against another thermometer. It was right on. No adjusting is possible to the reading.

I have had no problems like that at all.It has never gotten up to temp and come on every 5 seconds.I love this heater and it maintains the set temp,no problems.

Mine was off by two degrees. It was an easy correction and make sure you keep a thermometer in your fridge any way you decide to go. The difference in temp can also be affected by where you store your fridge and where you place the probe.

Yea happened to me too. I emailed them and they sent me a replacement part. I was told not to max out the heat temp. So I kept it less then a 100 deg. C from the max temp after I replaced the thermol . They did not charge me for the part either. So basically if I were you and if you have time to return it for a full refund and buy another one and keep it 100 c under the max temp you should be fine. You could email them and see if they will give you the replacement part but it was a little hard changing the part. But it can be done. It's been working fine ever since.

No problem with it showing but I don't believe it's a correct temp. It always shows much higher than the thermostat and what I believe it could be therefore I don't really go by that.

I have not measured it with a thermometer, but if the spacing on temp markings on the thermostat are consistent it would be trying to keep a temp of about 150 degrees F. However, the the temperature readings when measured seem to run hot and be somewhat uneven across the surface.

it sounds like the temperature control in your fridge is stuck at 58 deg. my fridge temp adjusts to what I set to.

I don't have an accurate enough thermometer to independently verify the temp. However the thermometer on the controller seems to indicate it's maintains the temp within 1 degree of what I set it for.

You should calibrate any thermometer but if you are getting weird readings try changing the battery. Acurite recommends a basic alkaline not a heavy duty. This worked for mine.

Did you calibrate it? You need to have or make a calibration sample at the correct temp and then adjust it. Mine was right on out of the box but they do vary
