Finnex Digital Temperature Controller

Pros: does a very good job

Cons: STILL CLICKS on/off not as bad tho

accurate easy to use i gave it a 4 because its not completely digital it still has a couple relays that have click noise when turning on and off not as loud as finex heaters with built on temp controller. i figured it should be silent. Come on FINEX nobody wants to hear the clicking noises!! AT ALL!!

precise control

I have 2 of these controlling Finnex 300W titanium heaters in my 100 gal display tank. The 2 HC810M's keep a steady, rock solid 78 deg in my tank.

Pros: accurate and reliable

Cons: none

I have used these controllers for years on my fresh water tanks and salt water. I run at least two heaters for redundancy using a power strip. I have run two 300 watt heaters at once with no problems. The high / low alarms are nice too and have saved my fish when a heater failed. I have had a couple fail but it was after years of used so I don't fault the controller. Nothing lasts forever.
