Do you have a question about the Geyserwise Delta T and is the answer not in the manual?
The central unit performing programmed functions and sending instructions to the pump and element.
Provides system status, geyser temperature, collector temperature, pump/element status, and electricity usage.
Measures geyser temperature and acts as a thermostat, including a thermal cut-out.
Senses collector panel temperature and relays information to the control box via an extension cable.
Suitable for 220V pumped solar hot water heaters, following manufacturer instructions for other components.
Installation, maintenance, and dismantling by trained personnel only, per manual and safety instructions.
Details operating voltage, relay ratings, voltage range, ambient temperatures, and temperature ranges.
Prohibits operation outdoors, in damp rooms, or where electrical components may be dangerous.
Highlights risks of electrocution and fire due to short circuits during installation.
Manufacturer not responsible for damage from improper installation, operation, or usage.
Outlines key steps: safety, control box, display, thermostat replacement, collector probe, connections, and setup.
Crucial precautions include switching off power at DB and testing with a multimeter to ensure no current.
Choose a dry location near the isolator switch, ensuring the control box is protected from elements.
Mount in an accessible location, not reachable by children, connecting cable to the control box.
Remove existing thermostat and install the GeyserWise temperature probe with built-in thermal cut-out.
Position the probe on the return side of the collector panel at its highest point for accurate temperature measurement.
