The 1242152 is the genuine-spec 740 digital timer control replacement panel for Autotrol valves, an electronic time-clock controller that fires regeneration on a fixed day interval rather than by metered water use. This is a discontinued part: Autotrol has moved production to the newer Select Easy-iQ control platform, so the 740 panel is no longer manufactured and is offered here as a legacy replacement while remaining stock lasts. It suits owners of older 740-based systems who need a like-for-like control panel rather than a full valve upgrade, and WrekinWater sells it honestly as an end-of-line part.

Symptoms that mean you need this part
- The existing 740 timer panel's display is dead, dim or showing corrupted characters
- The keypad has become unresponsive so regeneration days and times can no longer be programmed
- The panel loses its programming or the time/date resets every time power is interrupted
- You need a genuine-spec 740 replacement because a generic control isn't compatible with your existing valve wiring and camstack
Why it fails / why it matters
The 740 panel is a solid-state electronic timer that replaced Autotrol's original mechanical clock controls, using a keypad and LCD display to set the regeneration day pattern, time of day and cycle duration, then switching the drive motor accordingly. Being an older discontinued design, common failures are display and keypad degradation, capacitor ageing on the circuit board, and battery backup failure causing the panel to lose its clock setting on every power cut. Because Autotrol no longer manufactures the 740 platform, once genuine-spec stock like this is gone, owners of older systems will need to consider a full control upgrade to the current Select Easy-iQ platform rather than a like-for-like panel swap.
Why buy this from WrekinWater
WrekinWater has served more than 50,000 customers over 15 years from its Bettisfield, Shropshire base and deliberately keeps genuine-spec legacy stock of parts like the 740 panel so that owners of older Autotrol systems aren't forced into an unnecessary full valve replacement while a simple like-for-like control is still available. As specialists in Pentair Fleck, Autotrol, Clack and Kinetico parts, rated Excellent on Trustpilot, WrekinWater will tell you plainly when a part is on its way out, which is exactly the case here.
How to fit it
- Isolate the softener at the bypass valve and disconnect the transformer before removing the existing panel
- Note down your current regeneration programming (days, time, hardness setting) as this will need re-entering
- Release the fixing screws or clips holding the old 740 panel to the valve body
- Disconnect the wiring loom, motor cable and transformer lead from the old panel
- Fit the replacement 1242152 panel, reconnecting the wiring loom, motor cable and transformer lead in the same positions
- Secure the panel, restore power, and reprogram the regeneration days, time and hardness setting before running a test cycle
