6.1.5 GCL für einfache Schiebereglersteuerung eines Sollwerts
Das folgende Codesegment zeigt, wie ein Sollwert mit dem Schieberegler für die Pro-
dukte eZNT, eZNT-Wi und eZNTW-Wi eingestellt werden kann.
Variable lcdmode As Integer
//Timeout to a default display after no buttons touched for 8 seconds.
If (LCD0.Key_Press = 0) OnFor 8S Then eZNX_ScreenMode = 0 End If
//Define default screen
If (eZNX_ScreenMode = 0) Then
eZNX_SliderMode = 0 //Av518, allows GLC to control Line3
LCD0.Line2 = eZNX_RT_AV //set Line2 to display room Temp
LCD0.Line2Units = 2 //set units to degC
LCD0.Line3 = " " //blank line3
LCD0.Line3Units = 0 //blank line3 units
eZNX_StickyArrow = 0 // clear sticky arrow Av517
End If
//Read a press of the occupancy button (mapped as button 2)
IfOnce LCD0.KeyPress = 2 Then
eZNX_OVR = Not eZNX_OVR //toggle occupancy BV
eZNX_ScreenMode = 0 //return to default screen as previously defined
End If
//show occupancy status
If 'Occ Override' = On Then LCD0.Occupancy = 2 else LCD0.Occupancy = 1 End If
//if temperature icon (button 4) pressed
IfOnce (LCD0.Key_Press = 4) Then
eZNX_ScreenMode = 3 // temperature adjust mode
End If
//if slider is pressed on default screen
IfOnce (LCD0.Key_Press > 9999) And lcdmode = 0 Then
lcdmode = 3 //temperature adjust mode
End If
If (lcdmode = 3) Then
eZNX_SliderUnits = 2 //Av523 = units (degC) while under local control
eZNX_SliderMode = 1 //Av518 = local control, eZNX to controls line3 value&units
eZNX_SliderMin = LCD0_RT_MIN_SP //Av519 = min value
eZNX_SliderMax = LCD0_RT_MAX_SP //Av520 = max value
eZNX_SliderInc = 0.2 //Av521, how much to increment/decrement
//set initial value show to current temperature setpoint
IfOnce lcdmode = 3 Then eZNX_SliderValue = eZNX_RT_SP End If
If (lcdmode = 3) OnFor 2S Then
If eZNX_SliderValue Changed Then
eZNX_RT_SP = eZNX_SliderValue //update temp sp as value changes
eZNX_Occupied_SP = eZNX_RT_SP
End If
End If
End If
