Your facility most likely has some HVAC schedules already in place for your day-to-day operation of your HVAC equipment. To use Events2HVAC, you will eventually either need to deactivate those schedules or take steps to override them so that Events2HVAC can send commands to equipment automatically. Ideally, you want to leave your existing schedules in place in case the server is shut down and automatic scheduling through Events2HVAC is disabled. It is always a good practice to have a backup plan.
Most schedule objects in HVAC systems can be setup to work on a fixed daily schedule, a manual event schedule, or a holiday schedule. The schedule object commands one or more individual points that turn the equipment on or off. The command sent to these items are sent at a specify priority level. When setting up Events2HVAC, you will need to determine the individual points to command and the priority level at which the schedule object is sending the commands. When you define the actions for equipment, you will need to send the commands to those same points using a priority that is higher than your existing schedule object.
There are several schedule override strategies that can be employed when integrating Events2HVAC to your existing systems. Some require little, if any, preparation of the existing HVAC system. Others may require your HVAC technician to make some programming changes and/or add some additional objects. This document describes four different methods for overriding schedules in the case of an outage.
