6 Best Alternatives to the Heagstat 5-1-1 Day Programmable Thermostat (2026)

How these models compare to Heagstat

Suuwer 5-1-1 Day Programmable Multistage Thermostat

The Suuwer S715 matches the Heagstat H715 in 2-heat/2-cool staging and 5-1-1 day programming. Both units support conventional single and multi-stage systems without requiring a C-wire. The Suuwer model uses a blue backlight instead of the Heagstat’s off-white body, which may suit different decor preferences. Dimensions are nearly identical, with the Suuwer measuring 4.72 inches wide by 3.86 inches high. If you prefer a blue display accent while keeping the same wiring simplicity and stage support, this is a direct swap. It offers no smart features or app control, maintaining the manual-only operation style of the original.

Honeywell Home T6 Pro Wi-Fi Thermostat

The Honeywell Home T6 Pro adds Wi-Fi connectivity and Apple HomeKit compatibility, which the Heagstat lacks. It supports both conventional systems and heat pumps, whereas the Heagstat excludes heat pumps entirely. This unit requires a C-wire for power, unlike the Heagstat’s dual power option. The Honeywell model features a 4.06-inch square face, differing from the Heagstat’s rectangular shape. If you need remote control via smartphone or voice assistants, this is the upgrade path. You gain automation and scheduling flexibility but lose the no-C-wire convenience and lower price point of the basic Heagstat model.

Suuwer Single-Stage Non-Programmable Thermostat

The Suuwer S701 is a non-programmable thermostat, offering only manual control compared to the Heagstat’s 5-1-1 day scheduling. It supports 1-heat/1-cool systems, limiting it to single-stage HVAC setups unlike the Heagstat’s 2-stage capability. The design includes a blue backlight and a similar rectangular form factor. This model is suitable if you prefer simple, set-and-forget temperature adjustments without programming complexity. It lacks the advanced stage support and scheduling features of the Heagstat. Choose this if you have a basic single-stage system and want straightforward manual operation without the need for battery backup or intricate wiring configurations.

Coiiwsei 2 Heat / 2 Cool Programmable Thermostat

The Coiiwsei RTH715 provides 2-heat/2-cool staging and programmable scheduling, mirroring the Heagstat’s core functionality. It supports conventional multi-stage systems without requiring a C-wire, similar to the original. The unit features a blue color scheme and a slightly larger footprint, measuring 5.00 inches deep by 3.82 inches wide. This model is ideal for users who want multi-stage support and basic programming without smart features. It offers no app connectivity or voice control. If you prefer a blue aesthetic and similar wiring requirements, this serves as a functional alternative with comparable stage support and manual operation capabilities.

Honeywell Lyric T6 4.09" Heat Pump Thermostat

The Honeywell Lyric T6 supports both conventional systems and heat pumps, expanding compatibility beyond the Heagstat’s conventional-only range. It offers 2-heat/2-cool staging and a 4.09-inch square design, differing from the Heagstat’s rectangular shape. This model requires a C-wire, unlike the Heagstat’s battery or hardwired options. It is designed for multi-stage heat pump control, making it suitable for homes with complex HVAC setups. If you have a heat pump and need reliable multi-stage management, this is a strong option. You sacrifice the no-C-wire convenience and basic manual interface for broader system support and specialized heat pump features.

Riseem Single-Stage 5-1-1 Programmable Thermostat

The Riseem STN605 offers 5-1-1 day programming for conventional single-stage systems, matching the Heagstat’s scheduling style but limited to 1-heat/1-cool stages. It features a blue backlight and a similar rectangular form factor. This model is designed for basic programmable control without smart connectivity or multi-stage support. It is suitable for users with simple HVAC systems who want reliable scheduling without app integration. If you have a single-stage system and prefer a blue display, this is a practical choice. You lose the 2-stage capability and off-white aesthetic of the Heagstat but retain straightforward programming and manual operation.
