The iO-WRP Wireless Relay Plus is a 4-channel industrial-grade wireless relay control system designed to wirelessly control or monitor HVAC and related electrical equipment where traditional control wiring is impractical or cost-prohibitive.
The system uses a Base Module (BM) and one or more Satellite Modules (SM) communicating over 915 MHz RF, allowing long-range, low-interference signaling without trenching or conduit runs.
This system is commonly used for:
Heat pumps
Condensing units
Exhaust and supply fans
Pumps
Lighting control
Industrial and commercial HVAC equipment
It is designed for commercial, industrial, and advanced residential HVAC applications.
Wireless Frequency: 915 MHz
Channels: 4 independent relay channels
Range: Up to approximately 1/4 mile line-of-sight
Communication Type: Wireless RF relay signaling
System Type: Base + Satellite architecture
Compliance: FCC Part 15 compliant (marked on units)
This is a control relay system, not a brand-locked HVAC accessory.
Compatible with:
Most HVAC brands (Carrier, Trane, Lennox, Goodman, Rheem, York, etc.)
Any equipment requiring dry contact relay control
Industrial control circuits within relay rating limits
Not dependent on proprietary thermostats or control boards.
Compared to other wireless relay solutions:
Offers multi-channel control (4 channels vs many 1–2 channel systems)
Uses 915 MHz instead of crowded Wi-Fi or Bluetooth bands
Designed specifically for HVAC and industrial environments
No cloud, subscription, or app dependency
More robust than consumer smart relays
Comparable in function to functional wireless I/O relay systems used in BAS and light automation, but simpler to deploy
