No. Icon Name Functions 1 ON/OFF Button for power on or power off 2 Presence Button for entering or exiting a present mode which is programmed. 3 Program Button for Time Scheduler, pressing this button allows date/time setting, while holding it allows schedule programming 4 - Minus Button for set-point adjustment, each operation of the Minus (-) button reduces the set point by 0.1 °C/0.5 °F or 0.5 °C/1.0 °F which is defined in controller's setting.
Display Panel 3261Z02 The display panel shows actual room temperature, set point, energy mode, fan speed, time, weekday and etc. The graph below is an overview of contents that may show on the display panel. The following table lists the meanings each icon on the display panel represents: No. 1 Contents Meanings Temperature area, it shows room temperature and set point in °C and °F, The temperature unit can be selected in service mode of room unit if relevant option was created by the controller.
Technical design: Timer For example, the following contents will be displayed on LCD: 3261Z04 Economy mode, Heating 3261Z03 Comfort mode, Cooling Setting date and time · By pressing PROG button, user will enter time and date setting. · Pressing button Plus or Minus can change the variables those are blinking on the screen. · Pressing OK button will confirm the changes and the cursor will move to the next variable automatically. Workflow 1.
3. After the number of minute is confirmed, the whole time area will blink. Pressing button Plus or Minus will switch time format between 12-hour with AM/PM and 24-hour. The view is showed as follows in 24-hour time format: 4. After the time format is confirmed, HMI-SG will jump to the view of year. The view is showed as follows: 5. After the year is confirmed, it will jump to the view of month and day. The view is showed as follows: 6.
Setting time scheduler · HMI-SG is integrated with time scheduler function. · The scheduler is working with 7 weekdays and 6 switches can be set up for each day. · By setting up the switch, the user can set a time point and select one operation in Auto mode. · The contents of operation are defined in controllers, and maximum 10 operations can be defined. · After setting up the switch, the selected operation will be performed automatically at the time point. Workflow 1. Hold PROG button.
5. After the confirmation of weekdays, pressing Plus or Minus again will jump to the following view. The first line is number of operation; the second line is time setting, the invalid time "--:--" is used to add a switch. 6. Press button Plus and Minus to set up time point and select an operation, and press OK to confirm the input. In any parts of time area, press OK when the cursor is located on "--" without a number is selected, the switch will be deleted, and HMI-SG will go back to viewing switch.
Technical design: Parameters Parameter initialization After the HMI-SG is connected to the controller and the communication is set up, it will start parameter initialization. Parameter indicator (P--) will be displayed on screen for a while. After parameter initialization is completed, it will be in normal view. The parameter can be edited in service mode.
2. Press Plus or Minus to input password, press Mode to confirm it. If the password is correct, HMI-SG will show a new view for user to select group name. Note If no group exists for some reason or the password is wrong, "---" will be displayed again. 3. Press Plus or Minus to select a group name, press Mode to confirm it, and then the following view will be shown. The numbers of the first line represent parameter ID, and the number of the second line represent its value. 4.
Edit local parameter HMI-SG software version and build number will be shown when coming to diagnostic mode. The software version includes 3 digits and the build number 4 digits. In diagnostic mode, pressing Mode button can view the following 9 local parameters. Some local parameters are read-only (RO), and others are readwritable (RW), the local parameter view will show as follows: Note No.
Display alarms When controller sends an alarm to HMI-SG, alarm indicator ( ) will be on and the alarm number should be displayed blinking on screen. When HMI-SG is informed by controller that the alarm is disappeared or the alarm is confirmed by user with pressing any button, it will return to the previous status. Notes Engineering The room unit receives its power from the connected controller via the 2-wire interface (low voltage, SELV).
