Operating instructions
Your ThermoSphere Micro Electric Boiler will
automatically begin operating when you turn on a hot
water tap, and water is flowing faster than 1.5 litres per
minute.
The heated water temperature can be set manually by
using the decrease and increase push buttons.
Temperature can be set between a minimum of 20°C and
the maximum of 50°C.
The display also shows water flow rate in litres per
minute (LPM).
The minimum flow rate that can be displayed is 0.1 LPM
and the maximum displayed is 99 LPM.
LED indicators
The LED indicator on the cover indicates the operational
status of the unit.
Slow flashing GREEN
Standby mode. Waiting for water to be turned on.
Flashing alternate RED and
GREEN
The unit is self-diagnosing an error that it will
attempt to resolve.
When the error has been resolved, the LED will
return to slow or fast flashing
GREEN
.
Fast flashing GREEN
Unit is operating and water is being heated.
Flashing RED continuously
Irresolvable error and mechanical lockout. Unit will
no longer operate until the error is cleared. See
error codes on page 19.
This cannot be resolved by switching the unit off
and on again. Manual intervention is required.
If this occurs you should call ThermoSphere to tell
us the error code and we will arrange for a service
technician to help resolve the problem either
remotely or via a site visit if required.
Repair should not be attempted by anyone
without consent from ThermoSphere as this
will void the warranty.
Solid GREEN
The inbound temperature of the water exceeds
the set temperature. No heating required.
Error codes
If the unit experiences some type of malfunction, the
LED indicator will also display an error code.
You will see Er appear in the temperature setting
window and then an alpha-numerical code in the
flow rate window.
For example the image above shows error code A6
which means the outlet water is 5°C above the set
temperature.
