1. What to Look for in a Heat Pump Thermostat (2025 Guide)

Heat pumps behave differently from gas furnaces orgulvlister.
Before choosing a thermostat, check these essential features:

1) Verified Heat Pump Compatibility

A thermostat must explicitly support:

• Heat pump mode
• O/B reversing valve
• Auxiliary (AUX) heat
• Emergency heat (EM heat) control
• Multi-stage compressor (Y1/Y2), if applicable

Choosing a non-compatible thermostat can cause:

• AUX heat running too much
• Higher winter bills
• Short cycling
• Poor comfort balance

2) Smart Controls & App-Based Remote Access

• Control temperature remotely
• Get freeze alerts during winter vacations
• Automate schedules
• Reduce unnecessary AUX heat usage
• Integrate with Alexa / Google Home

A smart thermostat adds both comfort and measurable energy savings.

3) Energy-Saving Intelligence

Look for thermostats with:

• Eco / Away mode
• Adaptive AUX heat control
• Weather-response adjustments
• Setback optimization
• Anti-freeze protection

These features can reduce winter HVAC usage by10%–20%.

4) Wiring Compatibility（24V Low Voltage）

Heat pumps use low-voltage wiring. Ensure your thermostat supports：

• C-ledning (felles ledning)
• O/B reversing valve
• AUX / EM heat terminals

Many 2025 models offerC-wire adapters, making installation easier for older homes.

5) Optional Smart Home Integration

Not required, but useful：

• Alexa voice control
• Google Home integration
• App-based routines
• Energy reports
