Battery Reserve
The battery reserve, after at least
three days of charging while con-
nected to the power supply is ap-
prox. 16 hours. During this time the
settings are retained.
Note: Do not disconnect the timer
for long periods from the power
mains. Deep discharging shortens
the service life of the timer.
– Switch off the heater only for serv-
ice work.
For interrupted power supply (e.
g., maintenance work or power
failure), the display extinguishes.
When the boiler is to be put out
of operation, perform one of the
following:
– Change the limiting temperature
for automatic heater switch-off on
the heater regulator TA 210 E.
or
– Set the operating mode switch on
the appliance to “I”.
