The controller software and firmware version are also displayed. 6.4.7.1 Clear Alarm Event Log Clicking this button erases any old information in the alarm log and resets all of the messages to the default “OK - No Alarm” condition. 6.4.7.2 Enable Economizer Operation. Checking this check box enables economizer operation.
6.4.7.7 Enable Zone Dehumidification The TCS can provide zone dehumidification by running the air conditioners and cycling electric heat on and off to maintain room temperature. Factory default for this value is disabled. Note: The airconditioner circuit breakers and wiring must be sized for concurrent operations air-conditioning and electric heat. Special dehumidification models are available for use with this feature.
6.4.8 TREND TAB The Trend Logger will access the Remote Site and Acquire the site information stored in the controller. This information is stored in a comma separated value file. The information stored is the Zone Temperature, Zone Humidity, OutDoor Temperature, OutDoor Humidity, Unit #1 Supply Air Temperature, Unit #2 Supply Air Temperature, Mechanical Run Time, and Economizer Run Time. The controller will store all of these values once per hour and will hold up to 128 hours of data.
6.4.
The Dial-Out Screen displays the Site name and Site phone number. The site name is included with other information when the TCS dials out and connects to a Printer. When the TCS dials out to a pager it sends the phone number of the site to the pager so the technician can call in to the site to see what the problem is. The site name that is stored in the controller is displayed and can be changed by clicking on the name The Site phone number is the phone number of the site for modem connection.
6.4.10 NOTES TAB The notes tab is just a group of 8 message boxes that can be used to make notes about the controller or leave messages concerning the controller for the next technician. Clicking on one of the message boxes allows you to type a message up two 32 characters long.
