total capacity by the percentage entered for Parameter P16 and uses that value as the initial average daily usage for each day of the week until water usage establishes new averages. The default is set for 30% of the capacity. In most installations this is acceptable.
•Parameter P17 has been preset to 0. Do not change this setting. P17 must be set to 2 for Performa 960 FA operation.
•Parameter P18 allows the installer to lock the Regenerant Dosage and Capacity values so they cannot be changed. When Parameter 18 is set to 1, those two settings can only be viewed when the control is in the Level II mode. The settings will be skipped when the control is in the Level I mode. When Parameter 18 is set to zero, the Regenerant Dosage and Capacity can be viewed and changed in either Level I or Level II.
•Parameter P19 is used at the factory to enter default values. This parameter does not need to be changed. Using this parameter will erase the values for all other parameters and replace them with default values.
Improper regenerations will occur if P19 is set to a 0 or 3. P19 should be set on default number 99.
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 8 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 Factor A 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 filter 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 with parameter P15.
Fixed Reserve
When the fixed reserve is selected, the control multiplies the maximum system capacity by the percent value set in parameter P16 and uses the result as a reserve.
