Page 6: About
When the temperature is reached the unit will turn the element off until the water temperature falls. Once the water is up to temperature, Solatherm units with diversion are able to divert surplus power for another purpose such as battery storage. The controller monitors the temperature of the stored water to ensure maximum hot water is maintained. -
Page 7: Display
Display Figure 1. Solatherm Control Units are independent from the grid and require no mains power connection to operate, hence, the unit will only operate and display user information when there is sufficient energy from the sun. It is normal for the LCD display and lights to flicker or not fully display in low light conditions. -

Page 9: Start-Up Procedure
Start-up Procedure NOTE: ENSURE HOT WATER VESSEL IS COMPLETELY FILLED WITH WATER BEFORE COMENCING START UP PROCEDURE. 1. Turn on Isolator. RED LED POWER LIGHT SHOULD BE ON. The LCD will illuminate and start to indicate incoming power (providing supply voltage is over 40 Volts). -
Page 10: Frequently Asked Questions
Q: The controller LCD and lights are flashing or resetting in the morning, during the day or at the end of the day? A: The Solatherm control unit is powered by the photovoltaic array. There is no connection to mains/grid power required for standard operation. The controller will only operate when sufficient energy is available from the sun. - Page 11 Q: Run out of hot water or warm water only. 1. The hot water produced has been consumed during the day. 2. Not enough solar input during the day. Ensure booster is connected and the AC boost timer settings are correct for the household demand or season.
