Watts Time Clock Valve Model: WS1TC Model: WS1.
MANUAL REGENERATION NOTE: For softeners, if brine tank does not contain salt, fill with salt and wait at least 2 hours before regeneration. If you need to initiate a manual regeneration, either immediately, or tonight at the preprogrammed time (typically 2 a.m.), complete the following steps. For Immediate Regeneration: Press and hold UP and DOWN simultaneously until valve motor starts (typically 3 seconds). Arrow will point to Regen if a regeneration is expected “Tonight.

Page WS1TC & WS1.25 TC Manual Introduction This manual is about a control valve to be used on water softeners or water filters. The manual is designed to aid water treatment equipment manufacturers in the selection of the various control valve options. Information in this manual is different than what is needed for installation and servicing of a particular water treatment system. This manual is not intended to be used as a manual for a complete water softener or filter.

Page WS1TC & WS1.25 TC Manual Control Valve Function and Cycles of Operation This glass filled Noryl1 (or equivalent) fully automatic control valve is designed as the primary control center to direct and regulate all cycles of a downflow regeneration water softener or filter. The time clock control valve can be set to perform downflow regeneration or simply backwash. The time clock control valve has two calendar options for regeneration frequency: 1.
WS1TC & WS1.25 TC Manual Page The user can initiate manual regeneration. The user has the option to request the manual regeneration at the delayed regeneration time or to have the regeneration occur immediately. Simultaneously press the UP + DOWN buttons to start a regeneration at the next delayed regeneration time. If a regeneration is to occur today an arrow will point to regeneration. For immediate regeneration, simultaneously press and hold the UP + DOWN buttons for three seconds.
Page WS1TC & WS1.25 TC Manual Drive Assembly The drive assembly consists of the following parts: • Drive Bracket • Printed Circuit (PC) Board • Motor • Drive Gears • Drive Gear Cover The drive bracket holds the PC board, the motor, the drive gears and the drive gear cover in place. The PC board receives and retains information, displays the information, determines when to regenerate and initiates regeneration. The PC board powers the motor.
WS1TC & WS1.25 TC Manual Page Injector Cap, Screen, Injector Plug and Injector The screen, injector and/or injector plug(s) are installed under the injector cap in an easy to access location on top of the valve. The injector cap contains four slots so no water accumulates in the cap. The injector cap is designed to be hand tightened. Under the injector cap there is an easy to clean removable screen to prevent fouling of the injector. There are two holes under the injector cap labeled “DN” and “UP”.
Page 10 WS1TC & WS1.25 TC Manual The refill flow control assembly is installed in an easy to access refill elbow located on top of the control valve. The refill flow control assembly is attached to the control valve with a locking clip. The locking clip allows the elbow to rotate 270 degrees so the outlet can be orientated towards the regenerant tank. The control valve has a standard refill elbow to which a 3/8” flexible tube can be connected.
WS1TC & WS1.25 TC Manual Page 11 Mixing Valve The mixing valve is installed on the outlet side of the control valve. The mixing valve is used to blend raw water with treated water. To adjust the blended water, close the mixing valve. Open a water faucet to the desired flow rate. Open the mixing valve until the desired hardness is reached. Close the faucet. Installation Fitting Assemblies The installation fittings are used to connect the optional bypass or the control valve to the plumbing system.
Page 12 WS1TC & WS1.25 TC Manual Bypass Valve The bypass valve is typically used to isolate the control valve from the plumbing system’s water pressure in order to perform control valve repairs or maintenance. The WS1 bypass valve is particularly unique in the water treatment industry due to its versatility and state of the art design features.

Page 14 WS1TC & WS1.25 TC Manual OEM General Instructions The control valve offers multiple procedures that allow the valve to be modified to suit the needs of the installation. These procedures are: • • • OEM System Setup Installer Displays & Settings (either 1-99 Days Between Regeneration option or 7-Day option) User Displays These procedures can be accessed in any order. Details on each of the procedures are provided below and on the following pages.
WS1TC & WS1.25 TC Manual Page 15 STEP 4SS STEP 4SS — Use UP or DOWN buttons to switch between: • 1-99 Days Between Regen; or • 7-Day. Press SET HOUR button to go to Step 5SS. or ➟ STEP 5SS STEP 5SS — Use UP or DOWN buttons to switch between 60 Hz or 50 Hz option. Press SET HOUR button to go to Step 6SS.
Page 16 WS1TC & WS1.25 TC Manual STEP 1ID Installer Displays & Settings (1-99 Days Between Regeneration option) STEP 1ID – From normal mode, press SET HOUR + UP buttons simultaneously for 3 seconds and release. ➟ STEP 2ID STEP 2ID – Regeneration Time: Set the clock to the hour the regeneration should occur by using the UP or DOWN buttons. An arrow points to PM after 12. Press SET HOUR to go to STEP 3ID. ➟ STEP 3ID STEP 3ID – Days To Regen: Set the number of days between regenerations.
WS1TC & WS1.25 TC Manual Page 17 ➟ STEP 6I7 STEP 6I7 – Tuesday Regeneration: To regenerate on Tuesday use the UP or DOWN button until the arrow points to Regen. If the arrow does not point to Regen a regeneration will not occur on Tuesday. Press SET HOUR to go to STEP 7I7. STEP 7I7 STEP 7I7 – Wednesday Regeneration: To regenerate on Wednesday use the UP or DOWN button until the arrow points to Regen. If the arrow does not point to Regen a regeneration will not occur on Wednesday.
Page 18 WS1TC & WS1.25 TC Manual Manual Regeneration Sometimes there is a need to regenerate the system sooner than when the system calls for it, usually referred to as a manual regeneration. There may be a period of heavy water usage because of guests or a heavy laundry day. An arrow will point to the word Regen if a regeneration is expected “tonight.” To initiate a manual regeneration at the preset delayed regeneration time, simultaneously press UP + DOWN buttons together and release.
WS1TC & WS1.25 TC Manual Page 19 and tighten the nut on to the ¾” drain line fitting. The nut is only designed for use with flexible polytube. Use other nuts if attaching different materials. To access the drain line flow control remove the locking clip by pulling it straight out. Pull fitting out and replace the locking clip so that it is not misplaced. The drain line fitting is pressed in and has an o-ring seal. In the ¾” elbow, the white flow control retainer is pressed in and has an o-ring seal.
Page 20 WS1TC & WS1.25 TC Manual Mixing Valve The mixing valve is an option on the control valve. If the control valve is ordered with a mixing valve it will be installed in the control valve assembly process. To adjust the blended water, close the mixing valve. Open a water faucet to the desired flow rate. Open the mixing valve until the desired hardness is reached. Close the faucet. Note: The use of the mixing valve requires modification to the valve body.

WS1TC & WS1.25 TC Manual Page 37 Service Instructions Drive Assembly Remove the valve cover to access the drive assembly. Disconnect the power source plug (black wire) from the PC board prior to disconnecting the motor plug from the PC board. The power source plug connects to the four-pin jack. The motor plug connects to the two-pin jack on the left-hand side of the PC board. The PC board can be removed separately from the drive bracket but it is not recommended.
Page 38 WS1TC & WS1.25 TC Manual Replace the motor if necessary. Do not lubricate the motor or the gears. To reinstall the motor, move the spring clip loop to the right and hold. Gently turn the motor while inserting so that the gear on the motor meshes with the gears under the drive gear cover. Release the spring clip loop and continue to rotate the motor until the wires are horizontal and the motor housing engages the small plastic bulge inside the drive bracket motor retainer.
WS1TC & WS1.25 TC Manual Page 39 The regenerant piston (the small diameter one behind the main piston) is removed from the main piston by pressing sideways and unsnapping it from its latch. Chemically clean in dilute sodium bisulfite or vinegar, or replace the regenerant piston if needed. To remove the main piston fully extend the piston rod and then unsnap the main piston from its latch by pressing on the side with the number.
