What’s the difference between low voltage and line voltage thermostats?

Both low voltage thermostats and line voltage thermostats are used for controlling heating/cooling systems. Although line voltage thermostats are commonly used for radiant, convection or resistance heaters that are powered by electricity whereas low voltage thermostats are commonly used with central heating systems. A line voltage thermostat uses direct current, 120 or 240 volts, rather than the usual 24V found in newer systems.

Tempro thermostats are line voltage thermostats.

What’s a piggyback plug?

A piggyback plug is for easy connection to a 120V AC grounded receptacle. Most of our K-Kontrol thermostats are available with a piggyback plug for easy installation. Simply plug the equipment you are trying to control into the plug, and plug the receptacle into a 120V outlet. Click here for more information.

How do I wire my thermostat?

The thermostat has three contact points. Most of our thermostats are wired for heating, unless specified otherwise. When you open the thermostat you should see a white wire that is at blue dot and another wire at the red (heating). The red is your power – do not move this wire. The wire on the blue dot needs to be moved to the yellow dot to be wired for cooling.
