12-pack non-programmable heat thermostat
The White-Rodgers 1E78-140 is a non-programmable digital thermostat designed for single-stage heating systems. It suits HVAC technicians and property managers who need multiple identical units for consistent installations. The vertical-profile device mounts on a wall and operates on 24 volt or millivolt circuits. This pack contains twelve new thermostats.
Manual control limits scheduling flexibility
The thermostat offers manual operation only, so temperature changes require physical adjustment at the unit. It provides precision control within plus or minus one degree Fahrenheit. The device is not compatible with electric baseboard heat and certain other system types. A backlit digital display ensures readability in low light.
Single-stage heat-only compatibility decides fit
This model works exclusively with single-stage heat-only configurations on 24 volt or millivolt wiring. It will not function with cooling, heat pump or multi-stage heating equipment. Verify your system type before purchase to ensure correct operation. The relay contact rating is 70 at 24 volts.

Questions about this item
Should I buy the 12-pack or individual units for my project?
The 12-pack supplies twelve identical thermostats in one carton, ideal for multi-unit installs or contractor stock; single units are available separately if you only need one.
What does the ±1 °F precision mean once the thermostat is installed?
The digital display and internal sensor maintain the set temperature within one degree Fahrenheit, so the space stays consistently close to your chosen setting without noticeable swings.
The relay is rated 70 at 24 volts — what load can it actually switch?
The 24 V relay handles typical gas-valve or millivolt heating circuits up to its rated contact capacity, but it is not suitable for electric baseboard or line-voltage loads.
