Raypak Hot Water Energy Management Control manual Reading Logged Data

READING LOGGED DATA

Under the "History Report" menu item, logged data can be retrieved from a RayTemp control, saved to a disk file, viewed graphically on screen, or output to a printer. To retrieve history, con- nect the RayTemp serial cable between the RayTemp and your laptop PC. Then select "Retrieve". The RayTemp will transmit logged data to your PC. This takes about one minute at 9600 Baud. A status window will be present while the data is being received. The logged data consists of a report, seven detailed daily graphs (Monday thru Sunday), and twelve monthly graphs (January thru December). A menu will appear from which you can view any of these graphs. This data will be automatically saved to a disk file, based on the file name in the report data. PTT creates a unique name for each file by setting the last position of the file name prefix. The codes are 0 thru 9 and then A thru Z. For examples REDLION.GIX will be saved as REDLION0.GIX, REDLION1.GIX, REDLION2.GIX, etc.

To view an existing history file select "Display", and select a file by pressing enter. After the graphs are prepared, a window will appear from which you can select any daily graph or monthly graph to view on the screen.

The "Print" option under "History Report" allows you to send site reports and graphs to any sup- ported printer. When this item is selected a directory of data files will appear. Point to a file using the arrow keys then press enter to select the file. A check mark will appear. Place check marks next to all data file you wish printed, then press Ctrl-Enter to continue. A second screen will appear for selecting graphs within a report. Place a check mark (press enter) by each graph you want includ- ed in the printed report. Press ESC to start printing.

USING YOUR PC, PTT AND MODEM TO CALL A CONTROL

If this is your first attempt at modem communication with a RayTemp control we recommend that you first try everything in your office using two phone lines. Connect the RayTemp to an external modem and connect this modem to one line and your PC modem to another. Next, configure the RayTemps modem as described in the previous section. Make sure that the modem’s auto answer “AA” light is on. Also, buy a modem cable from RayTemp - at least for your first installation. This will prevent 80% of your possible problems.

To “get on-line” with the RayTemp, start the PTT software and select “Options” from the menu bar at the top of the screen. Enter the port number (usually 1 or 2) for the modem connected to your PC and make sure the speed is set to 9,600. Then press Ctrl-Enter and select “TechTerm” from the menu bar. A set of seven windows will appear. Start entering the phone set up commands: “ATE1” “ENTER” Return should show “OK”. If not, re-enter.

“AT&F” “ENTER” Return should show “OK”. “AT&D0” (zero) “ENTER” Return should show “ok”.

For example, to place a call, dial “ATDT5551212” and wait for a “Connect” message (replace the “5551212” with your actual phone number). If the screen is blank, type “ATE1” and try again. Note: The “Modem” section on the menu bar does not work with the RayTemp. Once you see the “Connect” message in the TechTerm window press F1 and then F6 to begin communication.
