Troubleshooting; Weak Battery - HomeMatic IP HmIP-WTH-2 Montage- Und Bedienungsanleitung

Troubleshooting

Once the batteries have been inserted, the wall
thermostat will perform a self-test/restart (approx. 2
seconds). Afterwards, initialisation is carried out. The test
display will indicate that initialisation is complete: orange
and green lighting.
Never recharge standard batteries. Do not throw
the batteries into a fire. Do not expose batteries
to excessive heat. Do not short-circuit batteries.
Doing so will present a risk of explosion.
Used batteries should not be disposed of with
regular domestic waste! Instead, take them to
your local battery disposal point.

Weak battery

Provided that the voltage value permits it, the wall
thermostat will remain ready for operation also if the
battery voltage is low. Depending on the particular load,
it may be possible to send transmissions again repeatedly,
once the batteries have been allowed a brief recovery
period. If the voltage drops too far during transmission,
the empty battery symbol ( ) and the corresponding error
code will be displayed on the device (see „9.4 Error codes
and flashing sequences" on page 82). In this case,
replace the empty batteries by two new batteries (see „8
Replacing batteries" on page 79).
