AC Infinity UIS Transmitter & Receiver
The AC Infinity UIS Transmitter & Receiver is a two-pack of 2.4 GHz wireless bridges designed to replace the cable between a UIS smart controller and the devices it runs. It is the reach half of the UIS accessory pairing: where the AC Infinity UIS Control Plug extends what a controller can switch, this kit extends where equipment can sit, removing the cord run entirely so an exhaust fan mounted high on a far wall or a humidifier placed outside the tent still answers to its controller across the room.
Each link is a pair of small inline dongles. The transmitter measures 1.4 x 0.9 x 4.6 cm (0.55" x 0.35" x 1.81") and plugs into a UIS port on the controller through its 0.7 cm UIS male connector, while the receiver measures 1.6 x 0.9 x 3.4 cm (0.62" x 0.35" x 1.33") and plugs into the device end. Both draw power through the UIS connection itself, so there are no batteries or separate power supplies to manage. The radio is a direct 2.4 GHz one-to-one link secured by a matched ID code printed on each pair: units arrive pre-paired from the factory, there is no pairing procedure, and codes are not interchangeable between pairs. The link runs entirely without Wi-Fi or internet, and AC Infinity state it responds within milliseconds, carrying the full UIS control set of temperature, humidity and VPD triggers, timers and schedules through walls at up to 8 m (26 ft) per transmitter.
The kit includes two transmitters and two receivers, forming two independent links that control two devices from two UIS ports. Range scales with radio load: one transmitter reaches up to 8 m (26 ft), two on the same controller reach up to 5 m (16 ft) each, and three to eight reach up to 3 m (10 ft), with a clear path free of large obstacles recommended between each pair. Compatibility covers the AC Infinity Ai+ Environmental Controller, Controller 69 Pro+ and Controller 69 Pro, plus the CLOUDFORGE, CLOUDRAY, CLOUDLINE, IONBEAM, IONBOARD, IONFRAME and THERMOFORGE device series, taking in equipment such as the AC Infinity Cloudline Pro T Mixed-Flow Inline Fan. Its pre-coded pairs keep a device under full sensor-driven command up to 8 m (26 ft) from the controller with no cable run and no network dependency.
NOTE: the UIS Transmitter & Receiver works only with specific UIS controllers and devices; earlier controllers and non-UIS equipment are not supported, so check the compatibility list before purchase. The units are designed for dry, indoor use only, and wireless range shortens as more transmitters share one controller.

Cable-Free Control
A direct 2.4 GHz link carries UIS control through walls, up to 8 m (26 ft) away.
Pre-Paired Links
Each transmitter and receiver pair shares a matched ID code, so there is no pairing procedure at all.
Bus-Powered Dongles
Both units draw power through the UIS connection itself, with no batteries or separate power supplies.

Directions for Use
expand_more
- Check that the code printed on each transmitter matches the code on its receiver; pairs are pre-coded at the factory and codes are not interchangeable between pairs.
- Plug a transmitter into an available UIS port on the controller.
- Plug the matching receiver into the UIS cord or port of the device to be controlled.
- Position the device within range: up to 8 m (26 ft) with one transmitter, up to 5 m (16 ft) with two, or up to 3 m (10 ft) with three to eight, keeping large obstacles out of the signal path.
- Operate the device from the controller or AC Infinity app exactly as if it were corded; repeat with the second pair to control another device.
