❓ FAQ
🌡️ How does ±1°F thermostatic work?
A sensor monitors output temp and adjusts gas flow instantly – even if you change water flow or shower head settings.
📟 What does the LED show?
It shows both the temperature you set (desired) and the real output temperature. Also shows battery status.
🔋 How accurate is the battery indicator?
Very accurate. 4 segments – when it drops to 1 bar, replace the 2 D cells soon.
💧 Can I use a bucket or stream?
Yes, but you need a separate 12V water pump (not included).
🏔️ High altitude?
Works, but efficiency drops ~10% per 1,000 ft above 2,000 ft. Thermostatic still holds steady.
