Shutting Down

Solar iBoost+ can be left to operate year round. Should you wish to power it down (e.g.
during holidays) the following options are possible:

Switch off at the fused spur - No solar energy will be captured by the Solar iBoost and
timed settings will not operate.

Temporarily remove the batteries from the sender - No solar energy will be captured
but timed settings will continue to operate.

Select OFF in Winter/Summer/OFF timed settings. Solar energy will be captured but
timed settings will not operate.
Accumulated savings and programmed times are retained in memory.
Batteries are low in the sender unit – replace batteries at
earliest opportunity. Do not use rechargeable batteries.
The unit is no longer receiving messages from the sender unit.
Possible causes:
1. Batteries may be exhausted.
2. Solar iBoost+ is positioned too far or near to the sender.
3. Sender unit pairing button may have been pressed
inadvertently outside of the pairing process (see Pairing the
Sender).
The Solar iBoost+ unit is over its working temperature -
check that the unit is clear of obstructions and that there is
adequate airflow to the unit. The unit will automatically
recover when the internal temperature has reduced to
within the normal operating range.
The Solar iBoost+ will check for overload during
initialisation and during normal operation. If overload of
either heating circuit is detected the output will be disabled.
Check the load of the immersion heater and supply voltage
are within specification. This warning can be reset by power
cycling the Solar iBoost+ unit.
