Ajax Geyser Management Kit

Smart, safe and efficient control for high-power geysers.

Upgrade your electric geyser with intelligent control and maximum safety. The Ajax Geyser Management Kit combines the advanced Ajax WallSwitch with the robust Schneider Electric iCT 25A contactor enabling you to manage high-current geysers seamlessly from anywhere.

Standard Ajax WallSwitch relays are not designed to switch heavy loads directly. This kit solves the problem by using the WallSwitch only to control the Schneider contactor’s coil, leaving the contactor to handle the geyser’s high current draw safely.

Enjoy smart home convenience without compromising reliability:

✅ Remote Control & Scheduling: Switch your geyser on/off via the Ajax app or set automated scenarios.

✅ Energy Efficiency: Program heating to match off-peak hours or solar generation.

✅ Overload Protection: WallSwitch monitors power and protects against overcurrent, while the contactor switches the load.

✅ Simple Installation: DIN-rail mounting and straightforward wiring between WallSwitch and contactor.

Whether you want to reduce your electricity bill or automate your daily routine, the Ajax Geyser Control Kit provides the flexibility and safety you need.

Why You Need This Kit

• Prevents Ajax WallSwitch overload — WallSwitch is not rated for direct high-current geysers and will trip or shut off.
• Contactor does the heavy lifting, handling the full geyser load reliably and safely.
• Maintains full smart-home capability, with app control, energy data, and seamless automations.
• Protects your system, with built-in current, surge, and heat safeguards.
