Keywords: aquarium temperature controller, reptile thermostat with timer, PID aquarium thermostat, day night thermostat, terrarium heating controller
The DTC-120 combines PID-based heating control with a real-time clock and two programmable timer periods. Set separate daytime and nighttime temperatures while scheduling connected equipment, such as aquarium or terrarium lighting, through the timer-controlled outlet. An LCD shows settings and measured temperature; audible and visual alarms alert users to temperature deviations and sensor faults.
1. PID-based dimming control adjusts heating output to help maintain the selected temperature.
2. Independent daytime and nighttime temperature settings with a 24-hour real-time clock.
3. Two programmable timer periods (L1 and L2) for scheduled operation of connected equipment.
4. Large LCD with menu prompts, live temperature display, and clearly indicated operating status.
5. Over-temperature, under-temperature, and sensor-fault alarms.
6. Mounts on aquarium or terrarium glass, stands on a table, or fits into a suitable enclosure.
