Jump Start Digital Temperature Controller for Heat Mats

Precise Digital Control for Any Hydrofarm Heat Mat

A heat mat with a fixed warming output can overshoot or undershoot the ideal temperature for a specific crop, especially as ambient greenhouse temperature swings through the day. Jump Start's digital heat mat thermostat delivers more accuracy than a mat's built-in output alone, using a water-resistant stainless steel probe to hold a constant, chosen temperature.

It's compatible with all Hydrofarm heat mats, with a controllable range from 68 to 108 degrees Fahrenheit, a display that switches between Celsius and Fahrenheit, and built-in error codes that flag sensor or range issues so a grower can respond quickly.

Key Features & Benefits

• Water-Resistant Stainless Steel Probe — for accurate, durable temperature sensing.
• Controllable Range 68-108°F — holds a constant, chosen temperature for specific crops.
• Compatible with All Hydrofarm Heat Mats — LED mode indicator lights, 3-prong grounded plug.
• Celsius or Fahrenheit Readout — switch with the Up or Down button.

Who Should Use This Controller

Growers using any Hydrofarm heat mat who want precise, automated temperature control instead of relying on the mat's fixed warming output.

About Jump Start

Jump Start, a Hydrofarm brand, builds this digital thermostat as the precision control layer for its heat mat lineup, from the compact windowsill mat up through the commercial daisy-chain system.

Frequently Asked Questions

What is the controllable temperature range?

68 to 108 degrees Fahrenheit. That covers the target range for most seedling and cutting propagation.

How does the probe measure temperature?

It uses a water-resistant stainless steel sensor. The probe is what lets the thermostat hold a set point rather than just running the mat at a fixed output.

What does an E1 error mean?

The temperature is too low, has exceeded the range limit, or the probe is open. Checking the probe connection is the first troubleshooting step for that code.

Is this compatible with all heat mats?

Yes, it's compatible with all Hydrofarm heat mats, including Jump Start's windowsill and commercial mats. One thermostat can be moved between mats as a grower's setup changes.

Do I need one thermostat per mat?

For the commercial daisy-chain system, one thermostat controls the whole chain of up to 5 mats, but standalone mats used outside a chain each need their own thermostat if precise control is wanted. Check how the mats are wired together before buying more than one.
