WelTouch CY-210B Manual — Comprehensive Guide
Battery Replacement Schedule:
- Replace batteries once per year, even if the low battery warning (E3) has not appeared.
- Always use fresh Alkaline batteries. Do not use rechargeables (lower voltage causes erratic behavior).
- When replacing batteries, the schedule and time may reset. Keep a note of your program settings before popping the batteries out.
Step 4: Wire Connection
- Match your labeled wires to the CY-210B terminals.
- Tighten each terminal screw firmly.
- Push excess wire back into the wall to avoid interference.
Warranty and support
- Warranty period typically ranges 6 months to 2 years depending on vendor.
- For repairs, contact the vendor or manufacturer listed on the packaging or manual. Avoid opening the device yourself, as that voids warranty.
3.2. Mounting
- Use M3 screws at the 4 corner holes.
- Do not mount directly on metal without insulated standoffs (risk of short circuit).
- For high-noise environments (VFDs, motors), attach the grounding wire to the chassis ground.
Cleaning:
- Do not spray liquids directly on the thermostat.
- Use a soft, dry brush or compressed air to remove dust from side vents.
- Wipe the screen with a slightly damp (not wet) microfiber cloth.

Title: The Weltouch CY-210B Manual: Why You Need to Ditch the Paper and Master the Multi-Function Meter weltouch cy-210b manual
Subtitle: Unlocking the secrets of your soil, light, and pH meter without the tiny, confusing font.
Let’s be honest. You bought the Weltouch CY-210B because you saw those lush, green photos online and thought, “I need that. My plants are dying, and I need to know why.” Replace batteries once per year , even if
It arrived. You pulled out the instruction manual... and immediately regretted it.
That tiny, folded sheet of paper with 12 languages crammed into 4 square inches? It leaves a lot to be desired. If you’ve lost the original Weltouch CY-210B manual (or just can’t read the microscopic text), you’ve come to the right place. Step 4: Wire Connection
Here is the real-world manual for your 3-in-1 wonder gadget.
Q5: The backlight doesn’t turn on. Is it broken?
A: No. The CY-210B has a non-backlit LCD in many production runs. Only some premium versions include a backlight that activates when any button is pressed. If yours never lights up, it likely lacks that feature.
Step 4: Adjusting Brightness & OSD (No Physical Buttons?)
The CY-210B has no physical menu buttons. To adjust brightness:
- On Windows: Use your PC’s display settings (the monitor obeys software brightness).
- On Raspberry Pi: Use
sudo dtoverlay=vc4-fkms-v3d in config.txt, then adjust via desktop settings.
If the screen is too dim, ensure the USB cable is plugged into a blue USB 3.0 port (provides more power than USB 2.0).
