Cross Reference

We are confident in our position at the top, so we’re comparing our Tempro NEMA 4X Rated Line Voltage Thermostats with other top brands in the market. Tempro thermostats stand out with the following features:

  • Same bolt pattern as competitor models, ensuring easy replacement
  • More robust than competitor models for increased durability
  • 62% greater cross-sectional area in the copper spring, providing better performance
  • 63-97% larger contacts, ensuring superior conductivity & reliability
  • Tempro terminals use #10 screws with larger 0.38” diameter ring connectors for better conductivity, compared to the #4 & #8 screws used by competitors
  • Tempro uses an “O-Ring” seal between the base & main housing, providing a consistent, repeatable seal, unlike glue, which can be inconsistent & prone to leaks

Frequently Asked Questions

Your questions, answered.

I have a PECO, Honeywell, Johnson Controls, or other manufacturers NEMA 4X line voltage thermostat. Will yours work?

Yes! We offer direct replacement options from most of our competitors. Click here for a cross reference.


How do I wire my NEMA 4X thermostat?

The thermostat has three contact points. Most of our thermostats are wired for heating, unless specified otherwise. The red is your power – do not move this wire. The blue dot should be used for heating, and the yellow dot should be used for cooling. Click here for more information and illustrations.

What is a temperature differential?

When a switch changes states from open to closed. The difference between those two points is the differential, or hysteresis.

What’s a single stage vs. two stage thermostat?

Single stage thermostats are designed to control individual heating or cooling units independently. Two stage thermostats are designed to work with a heating or cooling system that operates at two levels, providing enhanced comfort and energy efficiency.

What is a NEMA rating?

NEMA is described as “standards that are useful in defining the types of environments in which an electrical enclosure can be used.”

Can I use a NEMA 4X rated thermostats outdoors?

Yes! Our NEMA 4X thermostats are rated for outdoor use, including agricultural, wet or corrosive environments.
