Common questions with regards to an installed system
Wired display and WiFi link is off
Possible cause:
-
Ripple Control by the power company
-
The isolator switch or circuit breaker is off
Power companies have control over the power of your hot water cylinder and can switch it off at any time with a remote signal to reduce the load on their grid during high usage times.
Action:
-
The solar water heating will not be affected and will keep on heating to a maximum temperature of 75⁰C after which the Eco Solar Controller will have an orange LED indicator flashing.
-
Wait for the power company to switch the system back on and it might take up to 6 hours.

Temperature probe installed too close to the element
This happens when the smart controller pick up a rapid temperature climb inside the tank which is not normal for water heating.
Action:
-
Open the water tap to check if the cylinder have water
-
Move the temperature probe further away from the element
-
The temperature probe is not supposed to be inside the PTC element but on the tank.
