Description
This Honeywell digital non-programmable thermostat gives homeowners simple, “set-it-and-forget-it” temperature control with a clear screen and basic up/down buttons. It’s designed for common low-voltage 1-heat/1-cool systems and millivolt appliances, with precise ±1°F control so comfort feels steady without the complexity of a programmable stat.
Key Features & Benefits
Straightforward Non-Programmable Control
Manual, non-programmable operation allows you to set the temperature and let it hold, ideal for customers who don’t want schedules or menus.
Easy-to-Read Digital Display
Horizontal LCD screen with large, clear numbers and simple up/down buttons for quick checks and adjustments.
Accurate Temperature Control
Maintains room temperature within about ±1°F of the setpoint to minimize swings and improve comfort compared to older mechanical thermostats.
Low-Voltage and Millivolt Compatible
Works with many standard 24-V single-stage heating/cooling systems and 750 mV millivolt equipment like some gas fireplaces and pellet stoves (not for 120–240 V baseboard heat or multi-stage systems).
Battery and Hardwired Power Options
Can be powered by batteries or low-voltage system power, providing flexibility for different install situations.
Setpoint and Clock Memory
Remembers the temperature setting (and time where used) during a power outage so you don’t have to re-enter everything when power returns.
Service-Friendly Reminders
Includes low-battery and optional filter change reminders to prompt basic maintenance.
Fahrenheit or Celsius Display
Can display temperature in °F or °C to match user preference.
