Air Handling Unit Sequence Controller

Air Handling Unit Sequence Controller is a specially developed micro controlled instrument to switch ON the AHU at first start up or with power resumption in a sequence from highest pressure area to lowest pressure are. Though it is a mandatory requirement for GMP, this feature is not supported with most of existing BMS or HVAC control systems. To meet the GMP requirement at present it is done with manual control which will be more time consuming and it may not fulfill requirement in total. The Air Handling Unit Sequence Controller is the total solution for this mandatory requirement. One instrument can control 8 Nos. of AHU irrespective of power rating of the blower motor. By cascading number of instrument it can control any number of AHU. 8 Channel sequence controller to handle 8 Nos. of AHU.Programmable timer for all 8 channels. Centralized operation (Start/Stop) & indication of all AHU at service floor. AHU status indication can be in parallel with the Status Annunciator in production area. AHU number will be displayed instead of channel number on 4 digit display.AHU status will be displayed on 2 digit display. In auto ON mode the AHU will be switch ON from CH1 to CH8 with corresponding AHU.In auto STOP mode AHU will be switch OFF from CH8 to CH1 with corresponding AHUIn Manual mode selected AHU can start and stop from the sequence controller.Over night Selection for AHU which are to be run overnight or non-production time. The existing AHU control will be modified with additional Auto/Man switch on local AHU starter panel which will also ensure the normal operation AHU in the event of shut down of sequence control. Available Models. 8 AHU & 16 AHU Ahu Sequence Controller With Status Indication For 16Ch
