*C Band is a range of temperature above and below
the target temperature.
Range: 1°F to 10°F (.5°C to 5.5°C)
Default value is 3°F
Screen number
Fahrenheit or Celsius
NOTE: The above settings are recommended at
initial installation. For maximum performance and
system efficiency, these settings should be modified
as required to meet such parameters as system
capacity, location and usage.
NOTE: The Control Band is disabled when the unit
is operating in PID mode.
Control Band (Proportional Only)
The Control Band sets the maximum temperature above and below the Target Temperature (which is determined
by the embedded microcontroller) between which the system temperature may deviate.
This provides a control dead-band that prevents the boiler from short-cycling in proportional mode.
NOTE: PID mode will be disabled if you adjust the
control band.
