Notes on Technetic Plus Efficiencies
In order to consistently achieve the system capacities and salt
efficiencies listed in Table 2, it may be necessary to change
the injector assembly supplied with the Technetic Plus. Each
Technetic Plus control valve is supplied with a standard “low
pressure” injector assembly based on system tank diameter.
This injector assembly is intended for system applications
with working water pressures below 60 psi. For system
applications with working pressure above 60 psi, remove the
“low pressure” injector and install an alternate “high
pressure” injector. The injectors are coded according to size
by the number of “bumps” molded onto the end of the
injector. Refer to Table 5 to find the correct injector based on
tank diameter and water pressure. To order replacement
injectors use the 7-digit part numbers indicated.
Regeneration
When the control begins a regeneration, the display will
alternate between Time of Day and Regen Time Remaining.
The Regen Time Remaining is shown in minutes. The control
will start and stop an internal motor which drives the cam
gear through the various regeneration positions. The control
uses the information entered in the parameters shown in Table
3 to determine how long each part of the cycle should last.
If power fails during a regeneration cycle, the cycle
completes normally when the power is restored.
Note: The REGEN button is only active when the display is
alternating between Time of Day and Capacity. When
programming Level I or II parameters, the REGEN button is
not active.
The Regen Time Remaining in regeneration will continue to
count down until the cam gear reaches the Service position.
Manual Regeneration
To initiate a manual regeneration, press the REGEN button.
This button is located on the front of the control. When you
press the REGEN button, the control performs a full
regeneration of the conditioner.
If you press this button again more than one minute after
regeneration begins, but before the regeneration is
complete, a second regeneration will start when the first
regeneration is finished.
The display will freeze and only show the Regen Time
Remaining as an indication that the second regeneration will
be performed. When the first regeneration is complete, the
second one will begin and the display will alternate between
Time of Day and Regen Time Remaining.
Automatic Regeneration
There are two ways to have the control automatically initiate
a regeneration: calendar override or normal metered water
usage.
Calendar Override
This feature is set in parameter P14. It can be set for
1 to 30 days. If it is set to zero, this feature is disabled. When
this feature is active, the control keeps track of the number of
days since the last regeneration and when that number equals
the value set in P14, a regeneration is automatically started at
the Time of Regeneration set in P2.
Normal Metered Water Usage
The control compares the water usage to the calculated
volume capacity of the system. The control uses the Capacity
parameter P5 divided by the Hardness parameter P3 to
calculate the volume capacity of the system. It also uses a
reserve value to determine if a regeneration is necessary. If
the water usage since the last regeneration is greater than the
system capacity minus the reserve, a regeneration is needed.
Note: If the water usage exceeds 150% of the system capacity
between regenerations, the control will automatically call for
a second regeneration the next day even if no water is used.
This feature is included to make sure that an exhausted resin
bed is completely recharged.
Reserve Options
There are two types of reserve options for this control: fixed
reserve and historical water usage pattern. They are selected
