Second RT Value
If dual RTD values are selected, the temperature value for the second RTD is displayed.
RT Deviation Trip Value
Displays the deviation level (1
rt–deV
st nd
If (1 – 2 RTD) >
RT Divert
Shows if diversion enabled for the above trip condition.
Divert Mode
Displays the divert mode configured (multi or single):
MULtI
– Up to eight divert set points,
SINGLE
– One divert set point.
Divert Number
Displays the number of the divert set point(s): 1, 2, 3, 4, 5, 6, 7 or 8 (used with associated
Set Point and Hot Water Set Temperature
Caution. Do not change divert numbers during a process (only before or after).
Divert Set Point 1
Displays the temperature set for divert set point 1.
Divert Hysteresis Point
Displays the hysteresis value set (in engineering units) common to all set points.
Note. Only activated on values above the divert set point temperature.
Time Hysteresis
Displays the time hysteresis value set between 0 and 9999 seconds (common to all set points).
Note. If product temperature reaches the set point value, forward flow is initiated
t-hyst
seconds after reaching this value. If the temperature drops below the setting in the
display, flow is diverted immediately.
Divert Set Point
Hot Water Set Temperature 1 (Models 1952 and 1953 only)
Displays the hot water control temperature set point for divert set point 1, used in conjunction with
associated divert number 1.
Divert Set Points 2 to 8
Displays the temperature for divert set points (from 2 to 8 as selected) used in conjunction with
associated divert numbers 2 to 8.
Hot Water Set Temperature 2 (Models 1952 and 1953 only)
Displays the hot water control temperature set point for divert set points (from 2 to 8 as selected)
used in conjunction with associated divert numbers 2 to 8.
