Range of RF Transmission
Because of interference from other devices and the building
structure, it is not possible to exactly define the wireless
transmission range.
General Guideline
The maximum distance between the W7070A Wireless ZAPP
Receiver and the wireless wall modules / the RT7070A
Wireless Handheld should be less than 30 meters, and there
should be a maximum of two walls between the W7070A and
the wireless wall modules / the RT7070A Wireless Handheld.
RF transmission between the W7070A and the
wireless wall modules / the RT7070A Wireless
Handheld may be disrupted by interference from
metal objects in the building (metal cabinets and
doors, mirrors, concrete ceilings, iron grills, alu-
minum laminated plates, radio transmitters such as
wireless phones, and power switching devices).
− Establish and check radio communication of the
wireless wall modules with regards to interference,
e.g. Use LonMaker or EXCELON in conjunction with
nvoRfState.LastCommand to verify a successful
transmission from the RT7070A Wireless Handheld
to the W707A Wireless ZAPP Receiver.
− If interference occurs, select an alternative location
for installation.
MOUNTING
Mount the wall module on an inside wall approximately 54 in.
(1.3 m) from the floor (or as specified on the installation
drawings) to allow exposure to the average zone temperature.
Do not mount the wall module on an outside wall, on a wall
containing water pipes, or near air ducts. Avoid locations that
are exposed to discharge air from registers or radiation from
lights, appliances, or the sun.

Removing the Housing Cover
The wall module comes with a sub-base that mounts
separately for ease of installation. The housing cover can be
removed as follows (see also Fig. 5):
1.
Insert the tip of an awl or a similar narrow, pointed
implement into the small hole in the latch.
2.
Pry off the cover.
Fig. 5. Opening the housing
Batteries
The batteries (two standard alkaline AA or LR6 or AM3
batteries) have a min. lifetime of 2 years.
Inserting Batteries
1.
Open the housing (see Fig. 5) by pressing the snap-on
lock on the bottom of the housing while removing the
cover.
2.
Remove any discharged batteries, if necessary.
NOTE: Batteries should not be disposed of in the household
garbage. You may be required by local law to
dispose of discharged batteries in a certain manner.
Always replace both batteries. Use only 1.5 V
mignon batteries of the type AA or LR6 or AM3.
Ensure that the polarity is correct (see Fig. 6 on
page 8).
3.
Insert the supplied (or replacement) batteries into the
battery compartment.
Low Batteries
If the batteries are nearing the end of their useful life, the
word "BATT" will appear in the LCD. This means that the
batteries must be replaced (see section "Inserting Batteries"
above).
