HVAC Units

This area of HVAC Unit page shows the following:

1.Each HVAC Unit has a page similar to above associated with it. The current view is that of the Kitchen HVAC Unit (Kitchen RTU – Roof Top Unit).

2.On the left side is the system information section that indicates current Outdoor Air Temperature, Schedule Status (Occupied or Unoccupied), Current HVAC Mode of Heat or Cool (this mode changes automatically based on space temperature verses space temperature set point), Current Space Temperature, Occupied Heating Set Point and associated raise and lower buttons, Occupied Cooling Set Point and associated raise and lower buttons, Unoccupied Heating Set Point and associated raise and lower buttons, Unoccupied Cooling Set Point and associated raise and lower buttons, Status of HVAC Unit controller and icons to return to Main (Home Page) or the associated Schedule for the selected HVAC Unit.

3.This graphic also shows the commanded status of the Economizer (Enabled or Disabled), Unit Fan (On or Off) and number of Heating (1-4) or Cooling Stages (1-4) commanded ON. Additionally the current Discharge Air (supply air to area served by the HVAC Unit) Temperature and state of Electrical Demand Limiting (Inactive or Active) are shown.

4.By touching or clicking on the CYAN colored background area of the Space Temperature or Discharge Air temperature you will be directed to a trend log of values for these points.

5.Energy Demand Limiting: When Active the box will say Active and the background will be RED. When Inactive the box will say Inactive and the background will be YELLOW. When Active the temperature set points for the HVAC Unit will be automatically raised 3°F (when in Cooling Mode) or lowered 3°F (when in Heating Mode). HVAC Units automatically switch between Cooling/Heating Modes to maintain room temperatures. Active condition exists when current electrical demand is within 2.5% of electrical demand set point.

6.The Occupied Cooling set point must ALWAYS be set 2-3°F higher than the Occupied Heating set point, otherwise a set point conflict will occur and the Controller Status indication will show ALARM state.
