Honeywell Home RTH20B: Simple 5-2 Scheduling
The RTH20B is a direct replacement for older models, offering straightforward 5-2 day programming. Best for buyers who want a dependable, easy-to-set schedule without smart connectivity. It supports 1 Heat/1 Cool configurations and includes a large display with clear font for daily use. This unit is ideal for homes where simple, reliable temperature control is the priority over advanced features. A potential limitation is the lack of WiFi or voice control, which means remote adjustment isn’t available.
Honeywell Home X2S: WiFi Thermostat
The X2S adds WiFi connectivity and compatibility with conventional or heat pump systems. Best for buyers who want remote control via smartphone and voice assistant compatibility (Matter, Alexa, Google Assistant, Apple HomeKit). It requires a C-wire for optimal operation, and some homes may need a C-wire adapter. Its flexible scheduling supports 5-1-1, 5-2, 7-day, and 1-week modes. Choose this if you want smart features and room for future expansion.
Honeywell Home RTH22B: Flexible Week Scheduling
The RTH22B supports 7-day, 5-1-1 day, 5-2 day, or 1-week scheduling. It is designed as a versatile replacement for older Honeywell models (2H/2C conventional or 2H/1C heat pump). It also offers decor-friendly interchangeable decorative accents in white or gray. This model is best for households seeking a flexible programming routine and a larger display for readability. A limitation is that advanced smart features aren’t mentioned beyond scheduling and display customization.
Honeywell Home RTH21B: Single-Stage With Color Accents
The RTH21B offers a 7-day, 5-1-1 day, 5-2 day, or 1-week schedule with customization options. It provides interchangeable decorative accents to coordinate with home decor, making it attractive for visually oriented buyers. This model is best for homeowners who value a mix of practical programming and aesthetic options. It replaces older thermostats like RTH2510 and RTH2410. A potential drawback is that it remains a non-smart option; remote control isn’t built-in without a separate smart hub.
Mysa Smart Thermostat: Geofencing And Energy Savings
The Mysa thermostat focuses on energy savings and remote control. It features geofencing to adjust temperatures as you arrive or leave, and offers 7-day scheduling. It connects directly to WiFi without a hub and supports a future Matter integration, aligning with buyers who plan to expand a smart home. This choice is best for energy-conscious users who want app-based control from anywhere. A limitation is that some smart-home integrations may rely on future Matter support for broader device compatibility.
Buying Guide: Thermostat Selection Essentials
What type of setup do you need?
Choose basic programmable if you want reliable schedules without smart features. Opt for WiFi or smart thermostats if you value remote access and voice control.
Do you have a heat pump or conventional system?
Some models are designed for 2H/2C heat pump setups, while others work best with conventional systems. Check compatibility with your current equipment before buying.
Is energy savings a priority?
Thermostats with scheduling flexibility and geofencing help reduce heating and cooling costs. Energy Star certifications are a helpful indicator.
