92
CH TOD setpoint
This Setpoint is used when the time-of-day input is on. If the ODR function is active, this
Setpoint provides one coordinate for the shifted (because TOD is on) outdoor reset curve,
as described for the CH Outdoor Reset parameter.
26
DBI time
None, 4 sec, 10 sec, 15 sec
58
Delta-T degrees
If the outlet is hotter than the inlet temperature by the amount given by this parameter, the
response defined for the Delta-T Limit Response will occur. Stepped Modulation Limiting will
occur as the temperature approaches this limit.
44
Delta-T delay
This parameter provides the delay time for the Delta-T limit.
44
Delta-T enable
This parameter enables or disables the entire delta-T limit function.
43
Delta-T exch/outlet
enable
Disable, Enable Delta-T, Enable Inversion Detection, Enable Delta-T and Inversion
Detection.
43
Delta-T inlet/exch
enable
Disable, Enable Delta-T, Enable Inversion Detection, Enable Delta-T and Inversion
Detection.
43
Delta-T inlet/outlet
enable
Disable, Enable Delta-T, Enable Inversion Detection, Enable Delta-T and Inversion
Detection.
43
Delta-T inverse limit
time
This provides the time limit during which inverted temperature is tolerated when one of the
two inverse detection option is enabled.
44
Delta-T inverse limit
response
If temperature inversion detection is enabled and it persists for the time given by the Delta-
T inverse limit time, then the response described by this parameter occurs.
The delay time used is the time specified by the Delta-T delay and the retry limit is the count
specified by the Delta-T retry limit.
44
Delta-T rate limit
enable
Disable then no modulation limiting occurs as the delta-T threshold is approached.
Enable, then the Stepped Modulation Limiting feature is active for Delta-T.
44
Delta-T response
If the temperature difference exceeds the limit and Recycle && delay is selected then the
burner control recycles and holds while waiting for a delay (see the Delta-T Limit Delay
parameter) to expire.
44
Delta-T retry limit
If either the Delta-T response or the Delta-T inverse limit response specify a retry limit, then
any recycles due to reaching the corresponding response threshold are counted. If this
count ever exceeds the “n” value, then a lockout occurs.
44
DHW
anticondensation
enable
This parameter enables or disables anti-condensation for the DHW sensor.
50
DHW
anticondensation
setpoint
If DHW anti-condensation is enabled, has priority, DHW is firing the burner, and the outlet is
below the temperature given by this parameter then the firing rate set to the Maximum
modulation rate until the temperature exceeds this by 4 degrees F.
50
DHW Connector
Type
Designates the Sensor type connected to the control for proper reading.
20
DHW D gain
This gain applied to the Differential term of the PID equation for the DHW loop.
34
DHW demand
switch
The source of DHW loop control can be specified to use different inputs.
34
DHW enable
This parameter determines whether the DHW loop is enabled or disabled. It may be
disabled to turn it off temporarily or because the application does not use this feature.
19
DHW forced rate
For DHW demand, if the DHW 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
DHW forced rate
time
For DHW demand, if this time is non-zero then, upon entry to Run, the firing rate will be held
at the DHW forced rate.
48
DHW frost overrun
time
This time indicates how long the DHW pump should continue to run after DHW frost
protection pump demand ends.
42
DHW frost
protection enable
The DHW frost protection feature can be enabled to turn the DHW pump and possibly fire
the burner whenever the DHW input sensor is too cold.
42
DHW high limit
This parameter enables or disables the DHW high limit function. It must be disabled when
the DHW input is used as a switch to indicate DHW demand.
