LTL Controls Digital Temperature Controller - Cooling

Digital Cooling Control for Steadier Grow Spaces - 40F to 108F Range

Heat build-up in a grow room stresses plants and wastes effort when you adjust equipment by hand. This digital controller switches connected cooling equipment to keep the space near your chosen temperature, and its display shows the current reading so you can check conditions at a glance. The control range runs from 40F to 108F (5C to 24C).

Sold as a single unit, it suits home gardeners running one tent or room, and it also fits a commercial grower who wants one controller per zone and orders more as needed.

Key Features & Benefits

• Digital temperature display — reads from 32F to 140F (0C to 60C), so you see conditions beyond the control range.
• Cooling mode — switches connected equipment to hold temperature down.
• 40F to 108F control range — covers typical indoor cultivation setpoints.
• Compact housing — about 6 x 10 x 3 in, so it fits easily near your equipment.

Who Should Use LTL Controls Digital Temperature Controller (Cooling)

Growers who manage temperature in vegetative growth or flowering rooms, tents, or propagation areas and want automatic control of ventilation or cooling equipment.

Frequently Asked Questions

Q: What does a cooling controller do?
A: It switches connected equipment on when the temperature rises above your setpoint. That helps keep the space from overheating without manual adjustment.

Q: What is the difference between control range and display range?
A: The control range is the span of temperatures you can set, here 40F to 108F. The display range is what the screen can read, here 32F to 140F.

Q: Is this the same as a heating controller?
A: No. Cooling and heating controllers act in opposite directions. Choose the cooling model to manage excess heat, and a heating model for warming equipment such as mats.

Q: Can I use it with ventilation equipment?
A: It is designed to switch connected equipment based on temperature, which includes ventilation. Check the equipment's electrical load against the controller's rating before connecting.

Q: How do I place the sensor?
A: Position the probe at canopy height, away from direct light and airflow from vents. This gives a reading that reflects what your plants experience.
