Important Precautions

Verify compatibility with the TVBA terminal board; PVIBH1A is not designed for the TVIB terminal board.
Confirm sensor type and channel assignment before installation.
Verify the required firmware and ControlST version.
IS220PVIBH1A is a legacy BPPB-based version; GE transitioned this product to the newer IS420PVIBH1B platform.
Do not assume IS420PVIBH1B is a direct plug-and-play replacement; terminal-board, firmware, ControlST, and configuration requirements should be checked.
