Pearl Prime is an entry-level greenhouse controller designed for light commercial pad-and-fan operations. It provides professional environmental control in a simple system that's ready to install and easy to support.
2. Who is Pearl Prime designed for?
Pearl Prime is designed for growers running straightforward greenhouse operations, such as hoop houses, small commercial grows, nurseries, and residential greenhouses. Pearl Prime gives you reliable automation without the learning curve of enterprise systems.
3. What type of greenhouses is Pearl Prime best suited for?
Pearl Prime is ideal for pad-and-fan greenhouses, hoop houses, residential grows, and anything that requires reliable control without complex customization. If your operation is straightforward and you want something that just works, Pearl Prime is the right fit.
4. What equipment can Pearl Prime control?
Pearl Prime uses integrated power relays to switch 120VAC loads directly inside the enclosure. It can control:
- Cooling: exhaust fans, pad pumps, pad walls
- Heating: heaters
- Ventilation: shutters, roll-up sides, HAF (horizontal airflow) fans
5. Does Pearl Prime include remote monitoring and alarms?
Yes. Pearl Prime connects to Link4 Cloud via Ethernet, allowing end users to monitor environmental conditions, receive real-time alerts, and view historical data remotely from any device.
6. Does Pearl Prime have UL508A certification?
Pearl Prime is not UL508A certified. It is intended for applications that do not require UL certification. Facilities requiring UL508A should use the full Pearl commercial system.
7. What support does Link4 provide after purchase?
Link4 provides U.S.-based technical support by live chat, email, and phone at 714-975-9474. All Pearl Prime units are covered by a 12-month warranty from the date of purchase.
8. How does Pearl Prime compare to the full Link4 Pearl system?
Pearl Prime is the entry point in Link4's Pearl family — optimized for simple, single-zone pad-and-fan operations where cost and ease of installation matter most. The full Pearl commercial system is designed for larger or more complex facilities that need multi-zone control, advanced customization, or UL508A certification. If you're unsure which fits your operation, Link4's support team can help you choose.
