Geyserwise Delta T – Temperature Differential Controller for 220V Split Pump Solar Geysers

Optimized Control for Thermosyphon Solar Systems and Electric Geysers

The perfect solution for managing both thermosyphon solar systems and traditional electric geysers, this device offers advanced functionality as both a precise geyser timer and a differential controller. Designed to enhance efficiency and ensure optimal water heating, it integrates seamlessly with 220V pumped solar water heating systems as well as standard geysers, providing a versatile tool for all your hot water needs.

Features & Benefits:

• Versatile Use: Ideal for both thermosyphon solar systems and conventional electric geysers, serving as an effective timer and differential controller.
• Intuitive Display: Features a user-friendly display showcasing water temperature, current time, day, heating mode, and any malfunction warnings, ensuring you stay informed.
• Custom Heating Preferences: Offers both automatic and manual heating modes with an easy temperature adjustment range from 30°C to 75°C. The default setting is preset at 55°C for your convenience.
• Multiple Temperature Settings: Four adjustable temperature settings cater to varied heating requirements, providing flexibility and energy efficiency.
• Programmable Daily Timer: A daily timer with four distinct settings allows for customized operation, ensuring hot water is available when you need it, without wasting energy.
• Alert System: Notifies you of error conditions with specific warning codes from E2 to E9, allowing for quick diagnostics and resolution.
• Safety First: An electronic thermostat with a mechanical thermal cut-out at 90°C offers added safety, particularly in solar systems that may reach high temperatures.

Technical Specifications:

• Operating Voltage: 230VAC / 50HZ, with a functional range between 220V – 250V AC.
• Reliability: A main relay contact rating of 30AMP (up to 4KW) and a clear temperature display ranging from 0°C to 99°C, including special indicators for extreme temperatures.
• Safety Measures: Features include a high temperature warning set above 84°C, dry heat detection for empty cylinders, and a mechanical thermal cut-out at 90°C.
• Precision Control: Temperature adjustment ranges from 30°C to 75°C for electrically heated water, with a temperature differential setting from 1°C and a switching differential of 6°C.
• Advanced Monitoring: Equipped with temperature probe failure detection and a broad probe range for both the geyser (-30 to +130°C) and the system’s solar differential (7°C – 15°C, default at 7°C), including an anti-freeze setting (0°C – 15°C, default at 5°C).

This device stands out as an essential component for anyone seeking to optimize their water heating system, combining functionality with safety, energy efficiency, and user-friendly operation. Whether you’re upgrading your current system or installing a new one, it provides the control and peace of mind needed to manage your hot water efficiently.
