DIGITAL OUTPUT DIRECT/REVERSE ACTION
In the FBVI-2U4-4T the digital outputs could also be set for reverse acting. This would be typically used
for controlling normally-closed heating valves. The digital outputs are N.O. (normally open) operation.
To set digital outputs for N.C. (normally closed) operation:
• For DO09, set reverseDO09 (D198) digital setpoint to On
• For DO10, set reverseDO10 (D200) digital setpoint to On
• For DO11, set reverseDO11 (D202) digital setpoint to On
• For DO12, set reverseDO12 (D300) digital setpoint to On
ANALOG HARDWARE OUTPUT RANGE OPTIONS
AO14 and AO15 ranges can be selected with the stg1OutType (A1) or stg2OutType (A2) analog setpoints if
both stages are set to heat. If AO15 is used for a variable fan, change the stg2OutType (A2) setpoint.
To customize the voltage ranges, use the following analog setpoints:
For the custom selection on AO14
• AO14_HiAOValue (A373) is 10V by default. This is adjustable.
• AO14_LowAOValue (A372) is 2V by default. This is adjustable
For the custom selection on AO15
• AO15_HiAOValue (A389) is 10V by default. This is adjustable.
• AO15_LowAOValue (A388) is 2V by default. This is adjustable
ANALOG OUTPUT DIRECT/REVERSE ACTION
The analog outputs are set up to be direct-acting as default, or 0 to 100% = low value to high value.
To set up for reverse acting, (0 to 100% = high value to low value)
• For AO14, set reverseAO14 (D205) digital setpoint to On
• For AO15, set reverseAO15 (D206) digital setpoint to On
