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.

Time of Day Schedules & Holidays for HVAC Units and Lighting Zones

By touching or clicking on any HVAC Unit or Lighting Zone Schedule icon from the Home Page you will see the following:

1. Each HVAC Unit and Lighting Zone has a separate and distinctive time of day schedule associated with it.
2. In this case you are looking at the Kitchen HVAC Unit schedule. The green areas indicate the Occupied Schedule and the gray areas indicate an Unoccupied Schedule. In this case the Kitchen unit is set to the Occupied Mode of operation from 4am to12amMonday through Friday and on Saturdays and Sundays the Occupied Mode of operations is from 4am to 1am the next day. Otherwise the unit is in the Unoccupied Mode of operation. In Occupied Mode of operation the HVAC fan runs continuously to maintain room or area Occupied temperature set points. In the Unoccupied Mode the fan, heating and cooling stages all cycle to maintain Unoccupied temperature set points. See additional sections of this document for more information on this.
3. Adjustments are easily made. See next page.
4. For stores where the dining room is closed and yet the drive through is open 24 hours you will want to touch or click on the ON icon from the Home Page Schedule icon associated with the Dining Room HVAC Unit.
   This will keep the HVAC Unit fan operating continuously for make up air to your hood exhaust system.

• By touching or left clicking your mouse on any green area of the schedule that section will then turn blue and you can edit it.
• Notice that Monday was touched or clicked on and the background color changed to blue for editing.
• You can drag your finger or mouse (double arrow) to a new Occupied start and/or stop time. In the case above the start was retained at 4am and the stop time has now been set to 6pm. The same adjustments for any day can also be made by using the up and down arrow keys in the lower left hand corner of screen.

By touching and holding your finger on any green area of the schedule or right-clicking your mouse that section will then turn blue and you are presented with a drop-down selection where you can: Delete the Event, Make an All Day Event, Apply the Schedule to M-F, Copy the Day to the next Day, Clear the Day or Clear the Week. This is very intuitive and easy to understand after just a few minutes.

1. By touching or clicking on the Special Events tab at the bottom left of the screen to can add and edit special events. The example above shows that on Sat December 25th of 2010 (Christmas) the schedule has been set to Unoccupied for the complete day.
2. It is very easy and intuitive to add special events or holidays for any unit or lighting zone that has a schedule associated with it. Additionally, just like indicated on previous pages use your finger or mouse to adjust the time of day for these events, either in the box in the lower right-hand corner or through the up/down arrow keys in the lower right-hand corner.

Data Logging and Trended Points

1. The following points are all selectable from the Home and/or HVAC Unit graphic pages by touching or clicking on the numeric value ( CYAN background color) shown for each: OSA Temperature (Outside Air Temperature), Peak Electrical Demand, KWH Monthly (monthly electrical consumption), KWH Yearly (yearly electrical consumption), Freezer (temperature), Cooler (temperature), Space Temp (space temperature for each area of building) and DA Temp (discharge or supply air temperature from each HVAC Unit).
2. The information above shows the Cooler temperature as an example. Note that in the upper left hand corner a time range can be selected from a drop down menu. You can elect to review the trend information by specifying a certain time range or values for Today, Last 24 Hours, Yesterday, Week-to-Date, Last Week, Last 7 days, Month-to-Date, Last Month, Year-To-Date (data may not be available for this time period) and Last Year (data may not be available for this time period). See item 5 below.
3. You can also place your finger or mouse at any point on the graphic line to see what an exact value was and the exact date and time that value was recorded.
4. Note that each point is trended or logged every 60 minutes, 24 hours per day, 365 days per year. The exception is Peak Demand which is recorded every 15 minutes, 24 hours per day, 365 days per year and KWH Monthly and KWH Yearly which are continuously recorded.
5. Also note that the WEBs controller has a limited amount of internal memory for holding and retaining logged or trended values. When this internal memory is full, older data values are overwritten by new recorded values. With this in mind you may not able to read data values from a long time ago. Typically the WEBs unit will retain the last 7-30 days of trended or logged data for each point. Honeywell offers a service that automatically retrieves and retains long term trended or logged data for you, as long as, a continuous internet connection to the WEBs unit is available. Consult with your Honeywell salesperson on the costs associated with additional service.

Electrical Demand Limiting and Lighting Photocell Adjustments

1. You reach this page by touching or clicking on the Lighting or Electrical icons on the Home page.
2. Demand set point is easily adjusted by touching or clicking on the plus or minus keys above. For retrofit sites a review of your past 12 months of utility bills will allow for a determination of what this value should be. Consult with your Honeywell sales person or local electrical utilities representative to help you make this initial setting. For new construction projects it may take 6 months to a year before this value can be accurately set based on a review of your utility bills. Once set there should be no need for further adjustment, unless there is a change in the way the utility company bills or charges you. When actual electrical demand is within 2.5% of the setting above the temperature set points for the HVAC unit will be automatically raised 3° (when in cooling mode) or lowered 3° (when in heating mode). HVAC units automatically switch between Cooling/Heating modes to maintain room temperatures.
3. Parking Lot Lighting and Signage Lighting controls operate the same, but each has a separate adjustable “turn on” set point based on outdoor light levels as sensed by one common outdoor photocell. Typically the values above are set at 3450; this has proven to be a good setting for lighting to turn on based on outdoor light levels. You may want your signage to turn on earlier than parking lot lights that is why there is a separate darker/lighter adjustment for each. Touching or clicking on darker or lighter will adjust the start point for each. Parking and Signage each have a separate (adjustable) time of day schedule associated with them. See icons on Home page and refer to Time of Day Schedules & Holidays section of this document for adjustments to these schedules. The Parking or Signage lights will start based on outdoor light level and adjustments above. In a non 24 hour store the associated schedule is used to enable or shut lights off when the store is closed and employees are all gone, no matter what the light level is outside. An Example may be as follows: Your employees show up for work at 4am – parking lot lights turn on by time of day schedule. At 5am your drive through opens – signage lights turn on by time of day schedule. When outdoor light level is high enough say at 6am the parking lot lights shut off by the photocell set point. As outdoor light level increases maybe the signage should shut off by the photocell set point (but it does not have to). As light level decreases late in the day or evening the parking and signage lights come back on by photocell. Store closes at Midnight and signage shuts off on schedule. Employees leave at 1am after clean up, parking lot lights and employee lights shut off by schedule.
