6. Inserting the batteries into the "FHT8R"
heating control
• Slide down and remove the wall holder on the back of the heating control.
• Slide down and remove the cover of the battery compartment (in direction
of the imprinted arrow on the cover).
• Insert two AA batteries; pay attention to the correct polarity. Look into the
battery compartment for an illustration of the correct polarity.
☞
We recommend to use high-quality alkaline batteries only.
Operation of the heating control using accumulators or conven-
tional zinc-carbon batteries is possible, operating time and
radio range of the heating control will, however, be reduced.
Furthermore, there will be a risk of malfunctions.
Make sure to insert the batteries correctly to avoid damage to
the electronic components of the heating control.
• Close the battery compartment.
• The heating control performs a short display test. After the display test, you
have to set date and time (see chapter 9, page 65).
• If the battery symbol (" ") is displayed on the LC display, the battery voltage
is low and the batteries should be replaced as soon as possible (see chap-
ter 13 a), page 94).
The same applies, if the radio range decreases or if data are no longer dis-
played on the LC display.
