Boiler pump overrun
time
This time indicates how long the Boiler pump should remain on after demand ends. 45
Burner cycle count Burner cycle count. Incremented upon each entry to Run. Can be written to a new value
(e.g. if the burner or controller is replaced).
5
Burner name This parameter allows each control to have a unique name. 18
Burner run time Burner run time. Measures the time spent in the Run state. Can be written to a new value
(e.g. if the burner or controller is replaced).
4
Burner switch This parameter enables or disables the burner control. When it is off, the burner will not fire. 17
CH
anticondensation
enable
This parameter enables or disables anti-condensation for CH and LL demand. 34
CH
anticondensation
pump Force Off
If CH anti-condensation is in control of the burner and this parameter is Forced off, then the
CH pump is turned off to warm up the heat exchanger more quickly.
34
CH
anticondensation
setpoint
If CH anti-condensation is enabled, has priority, CH or LL slave is firing the burner, and the
outlet temperature is below this parameter then the firing rate set to the Maximum
modulation rate until the temperature exceeds this by 4 degrees F.
34
CH D gain This gain applied to the Differential term of the PID equation for the CH loop. 24
CH demand source The source of CH loop control can be specified to use different inputs. 22
CH enable This parameter determines whether the CH loop is enabled or disabled. When disabled the
demand caused by the sensor assigned to the CH loop is ignored. It may be disabled to turn
it off temporarily, or because the application does not use this feature.
18
CH forced rate For CH demand, if the CH forced rate time is non-zero, then the firing rate will be held at the
rate specified here during that time. This parameter is also needed as the starting point for
Slow State, even if the forced rate time is zero.
32
CH forced rate time For CH demand, if this time is non-zero then, upon entry to Run, the firing rate will be held
at the CH forced rate.
32
CH frost protection
enable
The CH frost protection feature can be enabled to turn the CH pump and possibly fire the
burner whenever the CH input sensor is too cold.
27
CH hysteresis step
time
The time needed for one step of hysteresis shift, when the off hysteresis threshold or on
hysteresis threshold is shifted due to a burner-on or burner-off event, respectively. Zero
disables this function.
23
CH I gain This gain applied to the Integral term of the PID equation for the CH loop. 24
CH maximum
modulation rate
Provides the upper limit of analog output or fan speed during modulation when firing for CH
or LL slave mode.
41
CH ODR boost max
setpoint
For CH demand and when outdoor reset is active, the setpoint will be boosted if demand is
not met after a period of time. This parameter provides the upper limit for boosting the
setpoint.
24
CH ODR boost time For CH demand and when outdoor reset is active, the setpoint will be boosted if demand is
not met after a period of time. This parameter provides the upper limit for boosting the
setpoint.
24
CH ODR max
outdoor temperature
This parameter determines the maximum outdoor temperature for the CH outdoor reset
graph. At the maximum outdoor temperature the setpoint will be the minimum water
temperature.
24
CH ODR min
outdoor temperature
This parameter determines the X coordinate of one point on the ODR graph. At this outdoor
temperature the setpoint will be the CH setpoint (or the CH TOD setpoint, if TOD is on).
24
CH ODR min water
temperature
This parameter provides the CH setpoint when the outdoor reset temperature is at its
defined maximum.
24
CH of
f hysteresis The off hysteresis is added to the CH setpoint to determine the temperature at which this
demand turns off
23
CH on hysteresis The on hysteresis is subtracted from the Setpoint to determine the temperature at which
demand turns on.
