VCB-X Miscellaneous Setpoints
Daylight Savings Stop Date
This is the date in the Fall when the time clock automatically adjusts
itself backward one hour. If you are in a time zone that does not have
daylight savings time or do not want to use this feature, leave this value
as zero. High limit = 1231; Low limit = 0; Default = 0.
Main Fan Minimum VFD Voltage
Enter a value between 0.0 and 10.0 VDC for the main fan’s minimum
output voltage. The Fan Speed Status Screen will display 0% to 100%,
but the output will range from the minimum value set to the maximum
value set.
The VCB-X will reverse the logic of the output signal when a Zoning
Bypass Damper is used. High limit = 10 VDC; Low limit = 0 VDC;
Default = 0 VDC.
Main Fan Maximum VFD Voltage
Enter a value between 0.0 and 10.0 VDC for the main fan’s maximum
output voltage. The Fan Speed Status Screen will display 0% to 100%,
but the output will range from the minimum value set to the maximum
value set.
The VCB-X will reverse the logic of the output signal when a Zoning
Bypass Damper is used. High limit = 10 VDC; Low limit = 0 VDC;
Default = 10 VDC.
Economizer Signal Closed Volts
Enter a value between 0.0 and 10.0 VDC for the Economizer minimum
output voltage when the Economizer is fully closed. High limit = 10
VDC; Low limit = 0 VDC; Default = 2 VDC.
Economizer Signal Open Volts
Enter a value between 0.0 and 10.0 VDC for the Economizer maximum
output voltage when the Economizer is fully open. High limit = 10 VDC;
Low limit = 0 VDC; Default = 10 VDC.
Mod Heat Signal Low Volts
Voltage at which the Heating is at 0%. Enter a value between 0.0 and
10.0 VDC for the Modulating Heat minimum output voltage. When
performing reverse acting heating, the minimum position volts will be
the highest value. High limit = 10 VDC; Low limit = 0 VDC; Default
= 0 VDC.
Mod Heat Signal High Volts
Voltage at which the Heating is 100%. Enter a value between 0.0 and
10.0 VDC for the Modulating Heat maximum output voltage. When
performing reverse acting heating, the minimum position volts will be
the highest value. High limit = 10 VDC; Low limit = 0 VDC; Default
= 10 VDC.
Mod Cool Signal Low Volts
Voltage at which the Cooling is at 0% if this is not a Digital Compres-
sor. Enter a value between 0.0 and 10.0 VDC for the Modulating Cool
minimum output voltage. When performing reverse acting cooling, the
minimum position volts will be the highest value. High limit = 10 VDC;
Low limit = 0 VDC; Default = 0 VDC.
Mod Cool Signal High Volts
Voltage at which the Cooling is at 100% if this is not a Digital Compres-
sor. When performing reverse acting cooling, the minimum position
volts will be the highest value. High limit = 10 VDC; Low limit = 0
VDC; Default = 10 VDC.
