Phyt AI Safety Documentation

Version: 1.0 Last Updated: January 2026

Important Safety Information

Read this entire document before installing or operating Phyt AI hardware.

⚠️ Critical Warnings

Electrical Hazards

Phyt AI hardware operates on low-voltage DC power but controls devices that may connect to mains AC power (valves, pumps). Improper installation can result in electrical shock or death.

  • Always disconnect power before working on the system
  • Never open the controller enclosure while powered
  • Do not expose the controller to water ingress
  • Use only the provided power supply or equivalent rated supply

Water and Electricity

Irrigation systems combine water and electricity in close proximity. This creates serious risk of electrical shock, short circuits, and fire.

  • Install the controller in a dry, protected location
  • Use weatherproof enclosures rated IP65 or higher for outdoor installations
  • Ensure all cable entry points are sealed
  • Never handle electrical connections with wet hands

Ground Fault Protection

GFCI protection is strongly recommended for any circuit powering Phyt AI hardware or connected devices.

A Ground Fault Circuit Interrupter (GFCI) can prevent electrocution by detecting current leakage. Install GFCI protection at the breaker or outlet level.

Fire Hazard

Electrical faults can cause fire. Reduce risk by:

  • Using appropriate wire gauges for all connections
  • Not exceeding rated current limits on relay outputs
  • Ensuring adequate ventilation around the controller
  • Keeping flammable materials away from the installation

Regulatory Notice

⚠️ This hardware is not certified.

Phyt AI Beta Hardware has not been tested or certified by:

  • FCC (Federal Communications Commission)
  • CE (European Conformity)
  • UL (Underwriters Laboratories)
  • Any other regulatory body

This hardware is provided for evaluation, educational, and personal experimental use only. It is not approved for commercial deployment or resale.

Use of uncertified radio frequency devices may violate local regulations. User assumes all responsibility for regulatory compliance in their jurisdiction.

Installation Requirements

Location

  • Indoor or protected outdoor location - Controller must be protected from direct rain, standing water, and condensation
  • Ventilated area - Allow airflow around the unit; do not enclose in airtight containers
  • Accessible - Install where you can safely access for maintenance
  • Away from high heat - Do not install near heat sources or in direct sunlight in hot climates
  • Stable mounting - Secure the controller to prevent falls or vibration damage

Electrical

  • Dedicated circuit recommended - Avoid sharing circuits with high-draw appliances
  • GFCI protection strongly recommended - Especially for any outdoor or water-adjacent installation
  • Proper grounding - Ensure your electrical system is properly grounded
  • Correct voltage - Use only the provided power supply (input: 100-240V AC, output: 24V DC) or equivalent
  • Wire sizing - Use appropriate gauge wire for valve and pump connections based on current draw and run length

Environmental Limits

| Parameter | Operating Range | | --- | --- | | Temperature | 0°C to 50°C (32°F to 122°F) | | Humidity | 10% to 90% non-condensing | | Altitude | Up to 2000m (6500ft) |

Do not operate outside these limits.

Wiring Guidelines

Controller Connections

  • Power input: Use provided power supply only
  • Ethernet to modules: Use provided CAT6 cables or equivalent shielded cable
  • Do not extend cable runs beyond 25 meters without consulting documentation

Valve Module Connections

  • Rated for 24V AC/DC solenoid valves
  • Maximum current per channel: 1A
  • Maximum total current: 4A
  • Do not connect pumps directly to valve outputs; use relay isolation

Sensor Module Connections

  • Use provided sensor cables with aviator connectors
  • Do not extend sensor cables beyond 10 meters without signal conditioning
  • Ensure connectors are fully seated and locked

General Wiring

  • Use stranded copper wire rated for the environment (outdoor-rated if applicable)
  • Secure all connections with appropriate terminals; do not rely on wire nuts in permanent installations
  • Route low-voltage sensor cables away from AC power lines to reduce interference
  • Label all wires at both ends

Safe Operation

Startup

  1. Verify all connections before applying power
  2. Inspect for loose wires, exposed conductors, or signs of damage
  3. Confirm GFCI protection is functional (test button)
  4. Power on and verify controller status indicators
  5. Test each zone individually before enabling automation

Ongoing Use

  • Periodically inspect connections and enclosures
  • Check for water ingress, corrosion, or pest intrusion
  • Monitor system alerts via the cloud dashboard
  • Do not ignore error indicators or unusual behavior

Shutdown

  1. Disable automation schedules in software
  2. Close any open valves
  3. Disconnect power at the source
  4. If servicing, wait 30 seconds after power disconnect before touching internal components

What To Do If Something Goes Wrong

Water Leak Detected

  1. Shut off water supply immediately (manual valve)
  2. Disable system power
  3. Identify source of leak
  4. Do not restore power until leak is resolved and area is dry

Electrical Fault / Burning Smell / Smoke

  1. Do not touch the equipment
  2. Disconnect power at the breaker or unplug from wall (if safe to do so)
  3. If fire is present, use appropriate fire extinguisher (Class C for electrical) or evacuate and call emergency services
  4. Do not restore power; contact support

Controller Unresponsive

  1. Check power supply and connections
  2. Check network connectivity
  3. Power cycle by disconnecting and reconnecting power
  4. If unresponsive after power cycle, contact support

Unexpected Valve Behavior

  1. Manually shut off water supply as precaution
  2. Check valve wiring connections
  3. Check software schedules and automation rules
  4. Contact support if behavior cannot be explained
