The IceCap Heater Controller connects up to two heating elements (sold separately) and gives you precise, accurate temperature control instead of relying on each heater’s own built-in thermostat — useful since many bare titanium and glass heater elements have no thermostat at all.
Capacity: dual grounded outputs, up to 1,000 watts combined
Temperature range: 68-93°F (20-34°C)
Resolution: 0.1°F/0.1°C
Accuracy: ±1°F/±1°C
Modes: on/off heating control
Warranty: 1-year limited
Running two heaters off one controller at half-wattage each (rather than one heater at full power) is a common reliability practice — if one element fails, the other still provides partial heating instead of the tank going fully cold.
Compatible with: most heating elements up to a combined 1,000 watts.
