CR24-B2E — staged room heat/cool logic

Belimo CR24-B2E differs from CR24-B3 and is described for VAV with staged heating/cooling control. Stage selection, damper feedback and supply-air temperature interlocks must be coordinated so opposing heating/cooling outputs do not energize together. Confirm exact actuator characteristics, stage relay outputs and environmental sensor inputs for the chosen code; a shared CR24 mechanical appearance is not proof of identical wiring or supported BMS protocol.
