The measurement on a lower point will result in an incorrect reading (lower temperature). This implication is that the panel will be warmer than the indicated temperature and therefore stop the pump too soon.

Check all of the above (More information on page 46) • Clean pump (More information on page 48) www.geyserwise.co.za Error code: E5 - Over temperature protection Possible cause: Geyser temperature exceeds 85°C Action(s): Open hot water tap to reduce temperature in geyser (More information on page 47) www.geyserwise.co.za... - Page 24 Remedial action The thermal pocket too close to the element. It's recommended that you contact an electrician or GeyserWise technician to deal with the E1 error code. Remedial action The following steps should be taken by the electrician or technician. PLEASE DO NOT DO THIS YOURSELF.
- Page 25 Switch off mains to geyser at DB board for 3 seconds. Switch the geyser back on at the DB board. Press the red power button on the GeyserWise to switch on element. You should see at least 1°C temperature rise in 20 minutes without any water withdrawals.
- Page 26 Remedial action Check if there is any water in the drip tray under the geyser. If there is any water, dry the drip tray and water www.geyserwise.co.za leak detector. The source of the water should be investigated. Error code: Communication failure Please note that the geyser element will not work during an E7 error code.
- Page 27 October until the end of March. This effectively means that the element does not switch on at all for six months of the year and all water heating is from solar. On the GeyserWise controller, use the following procedure to ensure the element seldom or never switches on: Press the SET button once and a temperature setting will appear.

We do not recommend temperatures as high as 90°C, but would like to offer a workable solution in case of higher temperatures. At the moment all our MAX models come with the following thermostat: Thermal cut-out sold with GeyserWise MAX model Cut-out temperature is at 90°C. *NB: Please note cut-out temperature. -
Page 29: How To Deal With Power Failure In Case Of 220V Pump Application
If a 220V pump is used in a pumped solar system there will be no back-up power to drive the pump in case of a power failure. The display of the GeyserWise will also not be working during the time the electricity is off. -
Page 30: Geyserwise Anti-Freeze Function
GeyserWise has an anti-freeze function where the pump will start circulating warm water from the geyser to the collector once the collector temperature reaches 5°C (default) to prevent the panel from freezing. Please note the appropriate panels for frost prone areas and anti-freeze valves are still needed. ESKOM also recommend an indirect system for frost-prone areas. - Page 31 Instruction manual Notes www.geyserwise.co.za...
