Cross Reference

We are certain of our position at the top so we’re comparing our industrial line voltage thermostats with other top brands. Tempro NEMA 4X Rated Line Voltage Thermostats compared to other models in the marketplace feature:

  • The same bolt pattern as competitor models
  • More robust than competitor models.
  • Copper spring is 62% greater cross section compared to the competition.
  • Contacts are 63-97% larger than competitor models.
  • Tempro terminals use # 10 screws with larger ring connectors @ 0.38” diameter for better conductivity compared to #4 & #8 screws used by competitors.
  • Tempro uses an “O Ring” seal between base and main housing for a consistent repeatable seal rather than glue, which is subject to inconsistency leading to possible leaks or glue drips.

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.
