2.7 Installing the b-touch control panel
2.7.1 Special points regarding the control panel
Positioning
• You can fasten the control panel either to the wall or to a
standard junction box.
• By default, the indoor temperature is measured by the IR
sensor next to the discharge grille.
The control panel contains a temperature sensor and a
connection for a possible extra temperature sensor. Posi-
tion the control panel in a logical place if you want to use
one of these sensors as an indoor temperature sensor.
Cabling
Note:
n
Take the following into account, otherwise errors
may occur:
- The control cable between the control panel and the
(first) connected unit may not be longer than 50
m(165 ft.).
- Keep control cables away from electromagnetic fields
and interference sources such as high-voltage cables
and fluorescent light starters, for example.
- Lay the control cables out straight or roll them in a
bifilar coil by folding cables in half before rolling
them. As a result, the magnetic fields will cancel each
other out to an important extent.
Note:
n
Use Biddle control cables only. Standard modular
telephone cable is NOT suitable.
Multiple units operated from a single control panel
• A maximum of 10 units can be connected to a single con-
trol panel. To do so, the units must be daisy chained.
• The total length of the control cables must not exceed
100m (330ft). If the distance becomes too great, an addi-
tional control panel must be connected.
• Only units from the same product series, with the same
battery type and preferably of the same capacity, can be
applied in combination with a single control panel.
