Product Description

The WHITE-RODGERS 01e78 140 is a single-stage, non-programmable thermostat designed for heat-only residential HVAC applications. Part of the Classic 70 Series, it operates on 24 VAC battery power and controls one stage of heating with a simple Heat-Off system switch. The vertical-mount design keeps installation straightforward, and the unit is millivolt compatible, making it suitable for gravity furnaces and other millivolt heating systems. Licensed HVAC technicians and heating contractors install this thermostat as a reliable, no-frills upgrade from older mechanical stats where programmable features are not required.

This thermostat fits residential heating-only setups where a single-stage gas furnace, boiler, or millivolt heating system is in use. Its RH and W terminal configuration supports standard low-voltage heating circuits. The non-programmable design suits rental properties, vacation homes, and any install where simplicity and dependability are the priority over scheduling features. It carries contractor branding availability, which makes it a practical option for service companies that want consistent product presentation across their installs.

Key Features

  • Single-stage heat-only control with RH and W terminals
  • Non-programmable operation for straightforward use
  • Millivolt compatible for use with gravity furnaces and millivolt heating systems
  • Battery powered — no common wire required
  • Vertical mount style with white housing
  • Contractor branding option available

Compatibility

Designed as an OEM-style replacement for single-stage heat-only residential heating systems using standard 24 VAC or millivolt low-voltage control circuits with RH and W terminal configurations.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable local mechanical codes. Power down or disable the heating system at the disconnect or breaker before removing the existing thermostat and making wiring connections. Verify millivolt or 24 VAC system voltage matches the thermostat specifications before energizing. Do not connect cooling or fan terminals, as this unit is rated for heat-only applications.
