Here are 2 example projects I created to demonstrate how to 'virtually' alter the timeout period of PIR's using logic code. They work by having 2 schedules that enable or disable the logic modules based on the time of day. The logic records the time that groups are switched on and turns them off after a defined period. The PIR's internal timer is disabled when the group is turned off. The first example project will work with 1 PIR and second project is designed to operate with multiple. This is not limited to PIR timers it will work exactly the same for key unit timers. Regards, Matty
