Heagstat vs Suuwer Specs Compared
programmability
The Heagstat H715 offers 5-1-1 day programming, letting you set separate schedules for weekdays and weekends with four distinct periods: wake, leave, return, and sleep. This allows for tailored temperature adjustments throughout your week. The Suuwer S701 is strictly non-programmable. You must manually change the temperature each time you want a change. If you want automated scheduling to save energy without daily input, the Heagstat provides that functionality. The Suuwer requires constant manual interaction to adjust settings.
system stages
Heating and cooling capacity differs between the two units. The Heagstat supports up to 2 heating stages and 2 cooling stages. This allows it to manage multi-stage conventional systems, which can provide more efficient heating and cooling cycles for larger homes. The Suuwer is limited to 1 heat and 1 cool stage. It is designed only for conventional single-stage systems. If your home uses multi-stage HVAC equipment, the Suuwer will not work correctly. The Heagstat handles more complex system configurations.
wiring requirement
Both thermostats operate on 24VAC power and do not require a common wire (C-wire) on most systems. They can both run on 2 AAA batteries as a backup or primary power source if the hardwired connection is insufficient. The Heagstat features standard terminals including RH, RC, W, W2, Y, Y2, G, and C. The Suuwer is compatible with 2 to 5 wires. While both avoid the C-wire hassle, the Heagstat offers more terminal options for varied wiring setups.
display type
Both units feature backlit displays for visibility in low light. The Heagstat has a 4.5 square inch off-white minimalist LCD screen. It is designed to match various home interior styles. The Suuwer features a blue backlit digital display. The Suuwer description notes it is suitable for middle-aged and elderly users due to clarity. Both screens provide clear visibility under different lighting conditions. The color difference is cosmetic, but both ensure you can read the temperature easily at night.
temperature control
Precision settings are nearly identical for both devices. Each unit maintains a temperature accuracy of ±1°F. You can adjust the temperature swing from 0.2°F to 2°F on both models to control how often the HVAC system cycles. Both include a built-in 5-minute compressor delay protection to prevent short cycling. The display range for both is 41°F to 95°F, with a control range of 44°F to 90°F. You get consistent comfort management from either choice.
Which thermostat fits your schedule
Users wanting weekly temperature schedules
The Heagstat H715 supports 5-1-1 day programming. You can set separate programs for weekdays and weekends with four periods per day. This allows precise control over wake, leave, return, and sleep times. The Suuwer S701 lacks this feature, making the Heagstat the better choice for automated scheduling needs.
Those preferring simple manual operation
The Suuwer S701 is a non-programmable thermostat. You adjust settings manually using its blue backlit digital display. It is ideal if you prefer direct control without complex schedules. The Heagstat H715 offers more features but requires navigating menus, which may be unnecessary for users who want straightforward manual operation.
People with 2-stage HVAC systems
The Heagstat H715 supports up to 2 heating and 2 cooling stages. It works with conventional single or multistage systems. The Suuwer S701 is limited to 1 heat and 1 cool. If your home uses a 2-stage system, the Heagstat ensures compatibility, while the Suuwer would not function correctly with your equipment.
