To upgrade an ET Pro3 or OptiFlow XR H2O controller to support 200 stations, you will need to order the WT2W-H2O-200STA-OFKEY part number which includes the following:
- WT2W-H2O-200STA-KEY (to go from 96 stations to 200 stations)
- WTOF-KEY-200 (OptiFlow 200 Station Key with v8.9 firmware)
Your existing ET Pro3 or OptiFlow XR H2O controller will need both items to support 200 stations.
This upgrade is available ONLY for the H2O 2-Wire platform. Conventional-wire controllers cannot exceed 96 stations.
If you currently have a 48 station controller, you will need to purchase:
- WT2W-H2O-48STA-KEY (to go from 48 stations to 96 stations)
- WT2W-H2O-200STA-OFKEY (to go from 96 stations to 200 stations, enable 200 station support with v8.9 firmware)
To upgrade, do the following:
1. Install the WTOF-KEY-200 to update the controller firmware (v8.9) to support up to 200 stations
2. Install the WT2W-H2O-48STA-KEY to go from 48 stations to 96 stations
3. Install the WT2W-H2O-200STA-KEY to go from 96 stations to 200 stations
