(From the calculation – assuming 4 operations per day on the thermostat, the esti-
mated 1-second scanning rate results in a battery life of 1 year. If the user in-
creases the scanning rate, the batteries’ life is extended.)
If the battery symbol
appears, the batteries are almost exhausted and should
be replaced. Use alkaline batteries type AAA.
Operating notes
The RDD100.1DHW provides Comfort, Economy and Protection mode. The differ-
ence between Comfort and Economy mode is only the room temperature setpoint.
