How to Connect and Configure EC/PWM and Aero Fans on Tent‑X

Summary This article explains how to connect and configure EC, PWM, and Aero fans with the EFC-1 and Tent‑X controller, including required adapters, device assignment behavior, expansion options, and basic controller settings.

Supported fan types and required adapters

  • EC or PWM fans: use the EFC-1 adaptor.
  • AeroFan: direct connection to controller or use FRC-1 or FRC-2 adaptors.
  • The EFC-1 is only for EC or PWM-type fans.

Physical connections

  1. Single fan

    • Plug the EFC-1 adaptor or AeroFan directly into the Tent‑X device port (RJ12).
    • Connect your EC/PWM fan to the EFC-1 adaptor.

  2. Two fans (intake + exhaust)

    • Use a Y-splitter in the Tent‑X device port and plug two EFC-1 adaptors or FRC-1/ FRC-2 remotes into the Y-splitter’s RJ12 ports.
    • Connect each fan to an EFC-1 adaptor or FRC-1/ FRC-2 remote.
    • The first connected fan becomes the exhaust (F1); the second becomes the intake (F2).
    • Fan assignment is automatic based on the connection order.

  3. More than two devices

    • You can daisy-chain fans to add more.

Notes on connection limits

  • The Tent‑X device line supports a maximum of two fan devices (F1 and F2) at the same time.

Adapter and fan selection

  • On the EFC-1 adaptor, select the fan type (EC or PWM) using the button on the adaptor.

Configuring fans in the Tent-X controller

  1. After connecting fans, their roles:

    • F1 = exhaust (controls temperature and humidity)
    • F2 = intake (maintains negative pressure)
    • Roles are determined automatically by connection order.

  2. Exhaust fan control modes (set on the controller for F1) with day and night settings

    • Cool only
    • Dehu only
    • Cool priority
    • Dehu priority
    • Cool and Dehu
  3. Intake fan settings (set on the controller for F2)
    • set negative presssure in %

  4. Speed limits

    • Set minimum and maximum exhaust fan speeds on the controller as needed.

Expansion and organization tips

  • If you only have one fan device, the Y-splitter is not necessary.
  • Use the SPH1 hub to keep multiple device connections organized instead of multiple daisy‑chained Y-splitters.

Troubleshooting tips

  • If fan roles appear swapped, verify the physical connection order: the first adaptor connected is F1 (exhaust), the second is F2 (intake).
  • Ensure you are using the correct adaptor for your fan type (EFC‑1 for EC/PWM; FRC‑1 or FRC‑2 for Aero fans).
  • When adding more devices, confirm you do not exceed two fan devices (FRC-1, FRC-2, EFC-1)on the Tent‑X device line.

Conclusion Connect EC/PWM fans with EFC-1 adaptors and Aero fans directly or with FRC-1/FRC-2. Use a Y-splitter only when connecting more than one device, or use the SPH1 hub for multiple ports. Fan roles are assigned automatically by connection order (F1 = exhaust, F2 = intake), and the Tent‑X controller provides mode selection and min/max speed controls for proper fan behavior.
