I. Installation: 3 Simple Steps for Most Scenarios
1. Pre-Installation Checks (Avoid Rework)
Specification Matching: Ensure the electric valve size (DN15/DN20/DN25 as mainstream specifications) matches the pipeline, and the threaded interface complies with national standards (G thread/BSP thread);
Environment Adaptation:
Temperature Range: Standard models (-10℃~+110℃); choose special anti-freeze/high-temperature resistant models for extreme environments (Nordic/high-temperature scenarios);
Protection Rating: ≥IP65 required for humid environments (bathrooms/basements) to resist dust and water splashes;
Smart Compatibility: When paired with a smart thermostat, confirm protocol compatibility (KNX/Zigbee/WiFi) to ensure "Seamless Integration with Smart Thermostats".
2. Core Installation Steps (No Professional Qualification Needed, One Person Operable)
Shut Off Supply & Relieve Pressure: Close the main pipeline valve, drain residual water/gas in the pipeline, and clean the pipeline interface (remove rust and dirt);
Fix the Valve Body: Install according to the direction indicated by the arrow on the valve body (medium flow direction), either horizontally or vertically. Wrap 3-5 rounds of PTFE tape around the interface for sealing, and tighten moderately with a wrench (avoid thread stripping);
Power On & Pairing:
Wired Models: Connect wires by color (corresponding to live wire/neutral wire/ground wire) and dock with the thermostat control terminal;
Wireless Models: After powering on, press and hold the pairing button (indicator light flashes), search and connect via the thermostat APP, then test "Thermostat-Controlled Precision" (set temperature and observe valve response).
3. Installation Taboos
Do not install in reverse (against medium flow direction), otherwise temperature control will fail;
Avoid installation near direct sunlight or high-temperature heat sources, which may affect the service life of electronic components.
II. Operation: 3 Control Modes for Different Needs
1. Smart Thermostat Control (Mainstream Recommendation)
Basic Operation: Set the target temperature via the thermostat panel/APP; the electric valve automatically achieves ±0.1℃ precise temperature control (Thermostat-Controlled Precision), dynamically adjusting flow instead of simple "on/off";
Scene Linkage: Set "Wake-Up/Sleep/Away" modes, and the electric valve responds synchronously (e.g., automatically reduces flow to save energy when away from home);
Voice Control: Supports Google Home/Amazon Echo, etc. Execute commands via voice (e.g., "Set the living room to 23℃").
2. Manual Emergency Operation (During Power Outage/Failure)
The valve body is equipped with a manual knob on the side; rotate to adjust the opening degree (0-100%) for temporary heating/refrigeration;
Automatically restores to thermostat control mode after power on, no additional reset required.
3. Centralized Control (Commercial Scenarios)
For office buildings, hotels, etc., set parameters for multiple electric valves in batches via a cloud platform, and synchronously receive energy consumption data from thermostats to achieve unified management.
III. Maintenance: Low-Cost Care to Extend Service Life to 10 Years
1. Regular Inspections (Once Every 6-12 Months)
Appearance: Check for valve body leakage and loose interfaces; re-tighten interfaces for slight leakage;
Function: Send commands via the thermostat to test response speed (normal ≤0.5 seconds) and ensure precise temperature control does not degrade;
Cleaning: Wipe surface dust with a dry cloth to avoid oil accumulation (no need to clean internal flow channels in areas with good water quality).
2. Long-Term Shutdown Handling
Turn off the power and drain medium in the pipeline to avoid corrosion from accumulated water;
For smart models, set "Shutdown Mode" in the APP for low-power standby (≤0.3W, complying with energy-saving standards).
3. Maintenance Taboos
Do not wipe with strong acid/alkali cleaners to avoid corrosion of brass/stainless steel valve bodies;
Do not cut off power frequently to prevent loss of thermostat pairing information.
IV. Common Troubleshooting (Solve 90% of Problems Quickly)
|
Fault Phenomenon |
Common Causes |
Troubleshooting Methods |
|
No response to thermostat commands |
Pairing disconnection/Power failure/Protocol incompatibility |
1. Re-pair the electric valve with the thermostat; 2. Check if the power socket is energized; 3. Verify protocol compatibility (e.g., KNX requires a dedicated gateway) |
|
Large temperature deviation |
Valve jamming/Inappropriate sensor position |
1. Rotate the manual knob 3 rounds to clear jamming; 2. Move the thermostat sensor (away from doors, windows, and air conditioners) |
|
Valve body leakage |
Aging gasket/Loose interface |
1. Replace with food-grade gasket; 2. Tighten the interface moderately (avoid over-tightening) |
|
Loud operation noise |
Unfixed valve body/Excessively fast water flow |
1. Fix the valve body with a bracket to reduce vibration; 2. Lower the maximum flow rate in the thermostat |
V. Usage Tips: Improve Efficiency and Service Life
Residential Scenarios: Pair with a smart thermostat for zone-specific temperature control, independently adjusting bedrooms and living rooms for energy savings and comfort;
Commercial Scenarios: Set "Unoccupied Period Frequency Reduction Mode" to reduce energy waste and operational costs;
Extreme Environments: Enable the thermostat's "Anti-Freeze Mode" in Nordic winters; the electric valve automatically circulates a small flow of medium to prevent pipeline freezing and cracking.
The core advantages of electric valves lie in "smart synergy + precise temperature control". Following this usage guide can not only maximize their energy-saving and convenient features but also extend their service life.
