Actual: ###.# Alm
Variable Description
Type Type will display the active staging
method.
Stg Seq Pump staging sequence from left
to right. A 0 indicates that a pump
is failed or disabled. See section
4.3.2 for information on alternat-
ing the staging sequence.
Stg Next staging value (N/A indicates
end of staging sequence or no
staging values set up)
Variable Description
Dstg Next destaging value (N/A indi-
cates end of destaging sequence
or no destaging values set up)
Actual Current value of the staging
variable
Table 7: Staging Variables
Note: “Stg” and “Dstg” will be displayed in units of
the active staging method shown in the “Type” field.
To change the staging type or values, see section
4.3.1.
3.4.5 Timers
Pressing NEXT, the controller will display the Timers
screen shown below. The numeric values on the left
are elapsed times, and the numeric values on the right
are the limits that they must reach prior to perform-
ing their respective action. See Table 8 for a descrip-
tion of the Staging variables.
← Pump MnRn:##/##m →
NFSD MnRn:###/###m
Stg PT:##/##
Dstg PT:##/## Alm
Variable Units Description
Pump Min Minutes Pump minimum run time,
Run
see section 4.3.1.3. When the
timer reaches its limit pumps
will be allowed to destage.
NFSD Minutes No flow shutdown minimum
MnRn run time, see section 4.5.6.
When the timer reaches its
limit, a no flow shutdown
will be allowed to occur. Note
that the timer immediately
resets to zero after expiring.
Stg PT Seconds Staging proof timer, see
section 4.3.1.1. When the
timer reaches its limit,
another pump will stage on.
Dstg PT Seconds Destaging proof timer, see
section 4.3.1.1. When the
timer reaches its limit, a
pump will stage off.
