Needreefunds Posted December 29, 2008 Share Posted December 29, 2008 Just a question, observance and perhaps mini-vent. I recently ordered a Finnex HMD-50 Titanium digital control heater from a vendor. Digital control heating indicator safety shut off overheat protection energy saving fast heating yadda-yadda IIRC they showed the picture of the box or the same picture of the unit that appears on the box. It was not mentioned that it has a separate temp sensor that must be installed in tank . This also is not shown in the picture on the box. Reading digital I also assumed it was fully electronic, but the constant clicking of what I think is the bi-metallic thermostat is driving me nuts. Never thought a heater would be the loudest piece of equipment in my system. Does anyone else have this unit and is it normal for the stat to cycle so frequently? TIA Quote Link to comment
Phixion Posted December 29, 2008 Share Posted December 29, 2008 Hmm, I actually considered one too! Maybe I'll rethink that... Seperate temp seonsor in the tank, please describe this. Is it like a seperate temp sensor thing that is wired to the external controller the heater is connected to? Quote Link to comment

They take a straight-on pic and put it on the box, hidden behind the heater cable is the temp probe cable lol. I would not have purchased this had I known....BUT, it does also provide you with the tanks temp as well, so perhaps its a wash...... Noisy little clicking bugger tho..... Quote Link to comment
Phixion Posted December 29, 2008 Share Posted December 29, 2008 Oh neat, so it displays both the heater set temp AND the actual tank temp? I wonder how accurate it is though. Quote Link to comment
Needreefunds Posted December 30, 2008 Author Share Posted December 30, 2008 Oh neat, so it displays both the heater set temp AND the actual tank temp? I wonder how accurate it is though. Yes, but not at the same time. There is an on/off/set button you press, then the display either blinks (temp setting mode) or is constantly on ( temp reading mode ). Not sure just how accurate it is yet , but there is a 3 deg diff between the Finnex display and a coralife digi thermometer that's in there now ( also prolly not the most accurate animal LOL ).

Phixion Posted December 30, 2008 Share Posted December 30, 2008 Gotcha, figured as much as it's a 2-digit display if I remember right. I'll bet each one is off in the opposite direction from the other, lol! And I'm sure if that's the case, eitherway the CoralLife is probably off by 2 and the Finnex by 1 maybe...

Well, on the plus side, they have both remained rather steady now for a good couple days. Stability is what I wanted in the first place. And if your tolerance factors are correct that should put me just about where I need to be...maybe?.. Quote Link to comment
celticsfan Posted December 30, 2008 Share Posted December 30, 2008 I had a Finnex TDH on a FW tank and hated it. It seems like trusty ol' Jager heaters still can't be beat Quote Link to comment
Phixion Posted December 30, 2008 Share Posted December 30, 2008 Ehh I've heard of more Jager failures than Stealth or Theo heaters... I agree though Needreef, consistancy rules over accuracy. Quote Link to comment
reefer714 Posted January 13, 2009 Share Posted January 13, 2009 Ehh I've heard of more Jager failures than Stealth or Theo heaters... I agree though Needreef, consistancy rules over accuracy. I bought it too and the constant on and off drove me nuts , too loud & and wasn't a clean looking install hanging off the back with green and red lights flashing- removed it it now is my perfect salt mixing heater with the built in probe. way too much noise for my liking btw; if the temp is off when compared to your other thermometer you can adjust it by carefully pealing the silver sticker on back removing just a bit of the top left and insert a small screwdriver in the hole and adj. the circuit board adj screw you see and calibrate it to your thermometer. Finnex told me about that fix. Quote Link to comment

Finnex told me about that fix. ....but what if I don't trust my thermometer either?? J/K thanks for the tip. Nice to be able to really calibrate the unit if need be. While this thing seems to provide excellent ( read steady ) regulation, the clicks make me wanna throw it out the back door..... I will most likely do the same with this one, demote it to the WC bucket. I just find it kind of funny that in every add I see for this heater they never picture or mention the probe. Click, click, click.....or...mebe its a pistol??? Quote Link to comment
