Calibration Guide
Great sleep starts with temperature. Your body needs to cool slightly to fall asleep and stay asleep. The HUB helps you control your mattress surface temperature, one of the biggest factors behind quality deep and REM sleep.
1. Start With Auto-Sleep Cooling “0”
“0” is your baseline.
Use it for 2–5 nights to let your body settle.
Auto-Sleep Cooling “0” intelligently makes micro-adjustments through the night to support your natural Deep Sleep and REM cycles.
It adapts as your core temperature rises and falls.
2. Adjust Based on How You Wake
Your body is the feedback loop.
Wake up warm → go 1 step cooler
Wake up cold → go 1 step warmer
Wake up neutral → stay where you are
Make one change at a time, then test for 2–3 nights.
3. If You Wake
If You Wake at 3am
This is usually overheating.
Drop your setting 1 point cooler and check your quilt.
If You Wake at 6am
Your body naturally warms toward morning.
Lower your setting 1 point and keep the room cool.
If You Wake Up Warm
Lower your setting 1 point and aim for a cooler room.
4. Science Note: Keep the Sleep Surface & Room Cool
Ideal Room Temperature
Most people sleep best when the room is: 15–20°C (sweet spot: 18–19°C)
A cooler room helps your body stay asleep and gives the HUB more room to work.
The Surface
Sleep science shows the sleep surface should stay within a cool, stable range.
Heating the mattress surface above ~25°C is generally not recommended, as it reduces deep sleep and increases wake‑ups.
If you need more warmth:
Increase room temperature, or
Use a warmer quilt, rather than raising the mattress temperature above this range.
5. Use Wearables to Fine-Tune
Wearables help you see how your body responds over time.
How to use them:
- Run “0” for 3–7 nights → get baseline averages
- Make a 1‑step change
- Hold for 3–7 nights
- Compare averages:
Deep sleep
REM
Wake‑ups
Resting heart rate
HRV stability
If your averages improve → keep the new setting.
If they drop → reverse the change.
Your goal:
fewer wake‑ups + more deep/REM + stable heart rate.
6. If Auto-Sleep Doesn’t Cooperate
Less than 5% of customers find Auto‑Sleep doesn’t match their sleep patterns.
If this happens:
Switch to Cooling (fixed temperature)
Start at a comfortable cool setting
Adjust 1 step at a time over several nights
Fixed cooling gives you full manual control and can be a better fit for certain sleepers.

Quick Tips
The ideal mattress surface temperature for quality sleep is 18–20°C, year-round.
The Auto-Sleep Cooling “0” setting is the best starting point for most people.
Everyone sleeps differently - adjust slightly warmer or cooler based on comfort or wearable feedback.
We recommend using cooling mode only, even in winter.
Adjust your room temperature and quilt thickness to match the season while keeping the bed surface cool.
Use the function button to cycle modes

Dual-Zone allows up to 12°C difference between the left and right sides of the bed.
The display shows the current water temperature.
When you tap to adjust, you’ll see the target temperatures so you know exactly where each side is targeting.
Auto-Sleep will intelligently adjust the pad temperature to support your deep and REM sleep.
Start with Cooling mode on “0 | 0” — this is the ideal baseline for most people.
Everyone’s sleep temperature is different. Adjust 1 point per night until it feels right.
Wake up too cold → Increase by +1
Wake up too warm → Decrease by –1
Wake up too early → Decrease by –1
If you use a wearable, test each setting for one full week and compare your averages.
Try 0 for a week → then –1 for a week → choose the best result.
For accurate calibration, aim for a 16–20°C room temperature.
Once you find your ideal setting, you’ll rarely need to change it.
If the bed feels too warm, use air-conditioning.
If it feels too cool, use external heating.
Maintain a 16–22°C room temperature for best results.
Allow 30–60 minutes for the HUB to cool the water in the pad.
Pre-Cool: With no one in the bed, the HUB can cool up to 12°C below room temperature (typically around 10°C for Queen and King).
Sleep-Cool: Each person adds body heat. Expect the displayed temperature to rise 2–3°C per person as the system absorbs your body heat.
For best cooling performance, keep your bedroom under 22°C (maximum 24°C).
The HUB 2 can heat the water in the pad up to 55°C.
For most sleepers, a 25–35°C range is ideal for comfort.
Temperatures above 35°C should be used only for recovery or therapeutic warmth.
If you naturally sleep hot, start at –4 in heating mode — or use cooling year-round.
Leave at least 15 cm of space on both sides of the HUB to ensure proper airflow and cooling performance.
Avoid tight bends or kinks in the connection tubing - this can restrict water flow and reduce cooling performance.
The side of the HUB that exhausts warm air may show a 1–2°C higher temperature on warmer nights or if airflow is limited.
This is normal and caused by the warm exhaust air heating that side of the unit.
