    24V heat pump thermostats
    control heating, cooling, and emergency heat, with popular smart options including ecobee Premium, Google Nest, and Honeywell Home models. These devices, often requiring a C-wire, are compatible with single or multi-stage systems. Key features include Wi-Fi connectivity for remote control and energy management, suitable for both conventional and heat pump systems. 
    Top 24V Heat Pump Thermostats: 
    • Smart/Wi-Fi: ecobee Premium/Essential, Google Nest, Honeywell Home (X8S/Smart), Sensi, PRO1 T855iSH.
    • Digital/Programmable: White-Rodgers 1E78-151, Copeland 5-1-1 Day, Honeywell Home Selectable-Flexible.
    • Specialized: Etopcontrols CH7500 (Heat Pump specific), Breeze Controls BC503, King Electric KRF-24V-KIT (Wireless). 
    Key Considerations: 
    • Wiring: Requires a C-wire (common wire) for constant 24V power, although some models offer battery-powered alternatives.
    • Heat Pump Compatibility: Ensure the thermostat supports O/B reversing valve terminals, emergency heat (E/Aux), and multi-stage heating/cooling.
    • Voltage: Compatible with 24-volt systems (ranging from mV to 30V AC).
    • Terminals: Look for R, C, Y, W, G, O/B terminals.

    People also ask
    Do I need a special thermostat for a heat pump?
    Why use a 24V thermostat?
    The benefit of these thermostats is that they use less power (around 24 Volts) to operate. Using low voltage thermostats, you can control all kinds of heating systems from boilers, furnaces, radiant heat, air conditioning, heat pumps, or baseboard heaters.

    Does the thermostat send 24V?
    The Thermostat: Your 24V Command Center. Your thermostat doesn't directly switch your furnace or AC on—it sends a 24V “signal” to the control circuits.Sep 1, 2025

    What is the difference between a millivolt thermostat and a 24 volt thermostat?
    For those of you who don't know, a millivolt system uses a thermocouple/thermopile with a standing (constant) pilot flame to generate a tiny “millivolt” signal used to control the furnace rather than the 24v signal modern thermostats use.
