Version 08/25/2021 Page - 20 Public Works Quote piece seal/ spacer stack assembly, and have an internal brine piston. Two (2) Control valves required. Control valves that do not meet these specifications are not acceptable. e. INTERLOCK WIRING: All interlock wiring between controls must be pre -wired and electrically tested by the water softening system manufacturer at the factory prior to shipment. f. MICROPROCESSOR CONTROLLER: The 24-volt solid state microprocessor shall have allow for easy access and remote mounting. The system shall be capable of operat ing as single, twin, design systems in an alternating fashion, parallel with multiple units on line at one time or as a demand recall/stage by flow system. The display shall be able to show time of day, current flow rate, total gallons used and volume remaining/days until regeneration, it shall be capable of initiating regeneration via meter delayed, meter immediate, time clock delayed or pressure differential. All cycle times shall be fully programmable and be capable of providing up to nine maximum cycle sequences including multiple cycles for each of the following: backwash, brine (a separate cycle from slow rinse) slow rinse, fast rinse and brine tank refill with treated water on either a pre-fill or post-fill basis. It shall be capable of operating on an optional clock basis with either a 7-day calendar or 28-day calendar, along with an optional 1 – 28 day calendar override and have up to (time periods) for regeneration to occur for either time clock or demand regeneration. Optional programming shall allow for pre-programming a multiple regeneration sequence in which the microprocessor can adjust the salting level automatically every so many regenerations, turn on a chemical feed pump to sanitize the media bed …etc. without any manual intervention. Two relay outputs shall be provided and controlled by the microprocessor to allow output signals based on time, a specific regeneration cycle window or volume of processed water from the meter output signal. The microprocessor must be capable of adapting to any external meter that provides an electronic pulse and be able to control up to four units and be able to add a second, third or fourth unit at a later date if needed to adjust to increased water usage demand. The diagnostics shall be capable of providing data days since last regeneration, gallons or gallons x 1000 since last regeneration, reserve history for the current day and previous 6 days, total volume processed for the current day and the previous 63 days by daily total and hourly, the peak flow rate for each of the last 28 days of operation along with the time of day for each day that the peak flow rate occurred, peak flows may also be viewed by the hour along with total volume processed through the unit. Indicator lights on the microprocessor shall indicate whether the unit is on line, in regeneration or on standby. Systemmate Controller to be used to monitor and record the flow rates of the system the flow. g. REGENERATION SEQUENCE: Up to nine maximum cycle sequences including multiple cycles for each of the following: backwash, brine (a separate cycle from slow rinse) slow rinse, fast rinse, and brine tank refill with treated water on either a pre -fill or post-fill basis. All regeneration cycles shall be adjustable and may have multiple occurrences. h. METER: -----2” electronic meters shall be incorporated into the control valves. Each meter shall be accurate from 1.5 – 150 gallons per minute at +/- 5%. i. DEMAND RECALL: Demand recall systems utilize motorized alternating valves (MAV) for demand recall purposes. The motorized alternating valve (MAV) shall be a 2” ported solid lead free brass 3-way valve with an electro-deposited epoxy coating NSF food grade material to protect against corrosion. The MAV allows multiple control valves to become a mult i-tank demand recall/ stage by flow system with one unit on line and the remaining units on stand -by or in regeneration. Note: only one unit is in regeneration at a time. It will provide no hard water bypass and the choice for treated water regeneration if desired. The MAV offers piping connections either 2” female pipe thread connection or you can use the 2.5” groove lock. The poppet valve internal design and its full 2” ports provide high flow rates with minimal pressure loss. The drive 24 Volt drive system is powered by the control valve so no extra power source or supply is necessary. The MAV has a sight glass that allows you to view the position of the valve to know which valve is on line and which is on stand by without removing any covers. Multi-tank demand recall/ stage by flow systems will have a MAV installed on each control valve with one port plugged. The demand recall/ stage by flow systems use a predetermined flow
