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.
48
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.
48
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.
41
CH has Priority over
Lead Lag
Yes, No, Cancel
19
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.
26
CH I gain
This gain applied to the Integral term of the PID equation for the CH loop.
26
CH maximum
modulation rate
Provides the upper limit of analog output or fan speed during modulation when firing for CH. 51
CH maximum
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.
27
CH minimum
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).
27
CH minimum
pressure
Provides the minimum Steam Pressure used to calculate the 4-20mA remote controlled
setpoint.
30
CH minimum water
temperature
This parameter provides the CH setpoint when the outdoor reset temperature is at its
defined maximum.
27
CH ODR boost
setup
Degrees or None
27
CH ODR boost
recovery setup time
mm:ss
27
CH ODR maximum
water temperature
This parameter determines one point on the ODR graph. At the maximum outdoor
temperature, the setpoint will be the minimum water temperature.
27
CH ODR minimum
outdoor temperature
This parameter determines the X coordinate of one point on the ODR graph. At that outdoor
temperature, the setpoint will be the CH setpoint (or the CH TOD setpoint, if TOD Is on).
27
CH ODR minimum
water temperature
This parameter determines one point on the ODR graph. At the maximum outdoor
temperature, the setpoint will be the minimum water temperature.
27
CH off hysteresis
The off hysteresis is added to the CH setpoint to determine the temperature at which this
demand turns off
26
CH on hysteresis
The on hysteresis is subtracted from the Setpoint to determine the temperature at which
demand turns on.
26
CH outdoor reset
If outdoor reset is enabled then the current outdoor temperature is used to determine the
Setpoint by interpolation using CH Setpoint (or CH Time-Of-Day Setpoint if TOD is on), the
min water temperature, and the min and max outdoor temperatures.
26
CH P gain
This gain applied to the proportional term of the PID equation for the CH loop.
26
CH pump cycles
Can be written to a new value (e.g. if the pump or controller is replaced).
6
CH frost overrun
time
This time indicates how long the CH pump should remain on after frost protection demand
ends. That is, whenever the pump has been on due to frost protection and then this demand
ends, it always continues to run for the time given by this parameter.
41
CH sensor or Inlet
The sensor used for modulation and demand may be either the Outlet sensor or a 4-20mA
Header sensor input.
25
CH setpoint
This Setpoint is used when the time-of-day input is off. If the ODR function is active, this
Setpoint provides one coordinate for the outdoor reset curve, as described for the CH
Outdoor Reset parameter.
25
CH setpoint source
Local
S2 (J8-6) 4-20mA
26
CH slow start
enable
This parameter enables or disables the slow start limit function for CH (or LL slave)
demand.
