External IC Temp Controller

The real time temperature is always showing on the temperature controller once the heater is correctly connected with the controller. And the red and yellow indicator on the controller exactly shows whether the heater is heating (red light on) or stops heating (yellow light on).

Over-heating Protection

When the water temperature reaches 36°C (97°F) accidentally, the controller display will flicker and the power load will be shut off. When it cools down, the heater will starts working again to keep a constant aquarium water temperature. The normal temperature range of this heater is from 60°F to 90°F. So please set your desired temperature within this range in order to extend the heater’s service life.

 Warnings and Warm Tips

1. Make sure the heater doesn’t touch sand or gravel on the tank bottom.

2. To avoid the device overheating and insure its better performance, it’s better to put the heater close to the tank filter.

3. Don’t plug in the aquarium heater if it’s not completely submerged in water.

4. Unplug the heater for 15 minutes before water change or cleaning fish tank. Otherwise, it would melt the case.

5. Always keep the heater rod and temperature probe fully submersible.

Question:Does this need to be used with a glass aquarium? I have a heavy duty stock tank that I need to heat indoors.
Answer:  Like all heating elements. Don't allow it to come into contact with the tank and you'll be fine.

Question:How long is the cord between the heating element and the display?
Answer:  Roughly 6 feet long. The suction cup I received with my unit was not strong enough to hold the display on the aquarium, so I put a screw in the wall just above the aquarium and hung the display on the screw. The company offered me a $5 rebate to buy hook to stick on the aquarium, I opted to place a screw in the drywa.

Question:Will it retain settings after power fail?
Answer:  We have not had a problem with it not retaining settings. It is doing a great job.

Question:Can this heater be installed vertical or must it be installed horizontal?
Answer:  Mine can go either way. The heater is and temp gage is waterproof. The Electronic read out hangs outside the aquarium.
