Daylight Savings Start Date
This is the date in the Spring when the time clock automatically adjusts
itself forward 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
at zero. High limit = 1231; Low limit = 0; Default = 0.
NOTE: The U.S. government has the authority to determine the
switch-over dates each year. Currently, the time changes
the second Sunday in March and then switches back the
fi rst Sunday in November.
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.
Building Pressure Control Low Volts
Voltage at which the control signal for Building Pressure is lowering the
pressure by the maximum amount. High limit = 10 VDC; Low limit =
0 VDC; Default = 0 VDC.
Building Pressure Control High Volts
Voltage at which the control signal for Building Pressure is increasing
the pressure by the maximum amount. High limit = 10 VDC; Low limit
= 0 VDC; Default = 10 VDC.
CO2 Sensor Calibration Offset
If the CO
2
Sensor is reading incorrectly, you can use this option to enter
an offset reading to adjust the Sensor’s Sensitivity. Enter a positive Sen-
sor Calibration to increase the CO
2
Sensor reading or a negative value
to lower the Sensor reading. High limit = 500 PPM; Low limit = -500
PPM; Default = 0 PPM.
Space Sensor Calibration Offset
If the Space Temperature Sensor is reading incorrectly, you can use this
option to enter an offset temperature to adjust the Sensor’s Temperature.
Enter a positive Sensor Calibration value to raise the Space Temperature
Sensor reading and a negative value to lower the Sensor reading. High
limit = 100ºF / 55.5ºC; Low limit = -100ºF / -55.5ºC; Default = 0ºF / 0ºC.
Supply Sensor Calibration Offset
If the Supply Air Temperature Sensor is reading incorrectly, you can
use this option to enter an offset temperature to adjust the Sensor’s
Temperature. Enter a positive Sensor Calibration value to raise the
Supply Air Temperature Sensor reading and a negative value to lower
the Sensor reading. High limit = 100ºF / 55.5ºC; Low limit = -100ºF /
-55.5ºC; Default = 0ºF / 0ºC.
