Controls
P1 Day of Week Programming
The day of the week is now displayed with the time of
day in the far left digit. It is programmed at P1 the same
as the time of day. The shift key will move the flashing
digit to the far left digit skipping the blank digit between
time of day and day of week. The day of week will
automatically increment at midnight. This change will
allow correlation of the daily usage history stored in L7
through L13 to days of the week. Use day 1 = Sunday
through day 7 = Saturday. Then L7 will hold the usage
history for Sunday through L13 holding the usage
history for Saturday. The daily averages stored in the L-
values will still be updated at the time of regeneration
not midnight. This is required to keep an accurate
record for reserve capacity needed at the time of
regeneration. The L-value displayed for the average
water usage for Sunday “day one” will be the average
water usage for Sunday at 2:00AM to Monday at
2:00AM. Assuming the time of regeneration is set for
2:00AM. To more closely match the averages to the
days set the time of regeneration to 12:01AM.
P19 Flow Sensor Select
P19 will not show 1.0, 1.5, 2.0, 3.0 for flow sensor sizes
as before. P19 will now show “0” for Magnum IT
NHWB, “1” for Autotrol 1 inch turbine, “2” for Autotrol
2 inch turbine, “3” for user programmable K-factor, and
“4” for user programmable pulse equivalent, “5” for
Magnum IT HWB. The K-factors or Pulse equivalents
for individual meters should be supplied by the
respective meter manufacturer. The control is no
longer preprogrammed for the Data Industrial 1.5
inch and 3.0 inch flow sensors. The default value is
“0” for use with the Magnum IT NHWB.
P20 K-factor or Pulse Equivalent
P20 is now used for user defined K-factor or pulse
equivalent. The range is 000.01 to 255.00 in 0.01 steps.
How this number is used is defined by the values stored
in P12 (units of measure) and P19 (flow sensor select).
P12 is used to define gallons or liters (0 = gallons, 1 =
liters). P19 is used to define K-factor or pulse
equivalent (3 = K-factor, 4 = pulse equivalent). K-factor
is defined as pulses per gallon or pulses per liter. Signet
and Sea-Flow are two flow sensor manufacturers that
publish a K-factor. The control can now use any flow
sensor as long as the programmed K-factor is correct.
The pulse equivalent is defined as gallons or liters per
pulse. The control will register 5 gallons of flow for
every pulse if P12 = 0, P19 = 4 and P20 = 5.00. Badger
Meter is one manufacturer that uses a pulse equivalent.
The control will not show flow rate if P19 = 4 (pulse
equivalent). This is because pulses are accumulated
over 10 seconds and flow rate is displayed in gallons
per minute. The control will always alternate between
time of day and capacity remaining or regeneration
time remaining.
P21 Remote Regeneration Delay
P21 is used to program the delay time for the remote
regeneration start. The range is 1 to 254 seconds in 1
second steps. The default is 60 seconds. This function
was added because customers are connecting
differential pressure switches to this input. A counter
starts when the conductors of this input are connected
with a dry contact closure. A regeneration will start
when the conductors remain connected for the
programmed time. The counter will reset to zero when
the connection is broken for at least 0.02 seconds. The
remote regeneration input cannot be used to perform a
double manual regeneration. The remote regeneration
input will be ignored when the control is doing a
regeneration.
P22 Factory Programming Use Only!
P22 is used by the factory for preset programming of
the 962 control. 99 is entered into this location by the
software. Any number entered into P22 will cause all
previous programming to be lost. If P22 is
accidentally entered via the set button and a digit is
flashing the control should be left to exit program mode
on its own. This will occur after 30 seconds. P22
should not be changed except at the factory!
Regeneration Cycle Advance
A function was added to advance the control to the
next stop position during a regeneration. Pressing and
holding the left arrow key for three seconds will cause
the control to advance to the next stop position of the
regeneration. The regeneration time remaining will
decrease by the amount of stop time that was skipped.
This function will not work when the motor is on. The
control will beep if the left arrow key is held for 2.5
seconds and the motor output is on. During
regeneration the control would not stop in the correct
position if time was skipped during a motor-on time.
Regeneration Cancel
To cancel a regeneration in progress press and hold the
LEFT (
←) arrow and set button for three seconds. An
“Err 3” will appear on the control, the motor will start,
and the control will advance to home. The cam may be
manually advanced to just prior to Regeneration
Complete. The control must be at least two minutes
into the regeneration before it can be cancelled.
Battery Backup Option
All 962 family controls are now battery backup capable.
There is a door in the backplate that allows access to
the battery harness. A 9 volt rechargeable battery is
available from GE Osmonics P/N 1075768. The battery
