**Discontinued** - Variable Speed Controller for Asynch. Pumps - Legacy Wi-Fi / Manual Control Model
AT-TWVSC**DISC**
Atlantic-OASE 73933 TidalWave Variable Speed Controller – Legacy Wi-Fi / Manual Control Model
CLEARANCE – Previous Generation Model with Built-In Controls
Take complete control of your Atlantic TidalWave TT-Series pump with the Atlantic-OASE TidalWave Variable Speed Controller (TWVSC).
This is the previous-generation / legacy version of Atlantic part #73933, featuring an integrated digital display and physical control buttons directly on the controller. Unlike the current-generation controller, you do not need a smartphone or app for normal operation. Pump speed, on/off operation and programming can all be adjusted directly from the controller.
For customers who prefer simple, traditional controls—or don't want to rely on a smartphone to operate their water feature—this legacy model can actually offer a significant advantage over the newer design.
Variable Speed Control
The TWVSC allows you to adjust the output of compatible Atlantic TidalWave TT-Series asynchronous pumps, giving you greater control over both water flow and energy consumption.
Pump output can be adjusted from approximately 25% to 100% across 10 adjustable flow levels.
Variable-speed operation is ideal for:
- Fine-tuning waterfall height, appearance and sound
- Increasing or decreasing pond circulation
- Reducing excessive water flow
- Reducing pump energy consumption when full output isn't required
- Temporarily reducing flow for fish feeding or maintenance
- Adjusting a water feature for different operating conditions or times of day
Built-In Digital Display & Controls – No App Required
One of the biggest advantages of this legacy TWVSC is its built-in LCD display and physical control buttons.
The controller can be operated directly at the unit, allowing you to:
- Turn the pump ON or OFF
- Increase or decrease pump speed
- Select from 10 flow settings
- Set the controller's internal clock
- Program automatic ON/OFF operation
A smartphone or mobile app is not required to operate the controller.
This makes the legacy model particularly convenient for commercial installations, shared properties, maintenance crews or homeowners who simply prefer physical controls.
Legacy Wi-Fi / App Capability
This generation of the TWVSC was also originally designed with Wi-Fi connectivity and compatibility with Atlantic's legacy TidalWave VSC mobile app, providing another method of controlling the pump.
Please Note: This is a legacy product and Atlantic has since transitioned to a newer control platform. Compatibility of the original TidalWave VSC app with current smartphones and operating systems cannot be guaranteed. The controller's built-in physical controls do not require the app.
Optional Handheld Remote Control
The legacy TWVSC can also be operated using Atlantic's optional handheld wireless remote control.
Replacement / Optional Remote:
Atlantic Part #74501 – Remote for TWVSC (Wi-Fi Legacy Version Only)
The remote is sold separately and is specifically designed for the legacy Wi-Fi version of the TWVSC.
Designed for Atlantic TidalWave TT-Series Pumps
The TWVSC is designed for use with compatible Atlantic TidalWave TT-Series asynchronous pumps up to 800 watts.
Using a separate variable-speed controller allows the pump and controller to remain independent components, making servicing or replacement easier than systems where variable-speed electronics are permanently integrated into the pump.

Important – Legacy Model
This listing is for the previous-generation Atlantic 73933 TWVSC with the digital display and physical control buttons.
It should not be confused with the current-generation Atlantic 73933 controller, which uses Atlantic's newer Bluetooth/app-based control system.
The legacy model allows the pump to be operated directly from the controller without requiring an app, making it an excellent option for customers who prefer straightforward manual controls.
