Check that the polarity of the batteries is
correct. Two commercially available AA type
(Mignon/ LR6) batteries (1.5 V) or
rechargeable batteries (1.2 V) are required.
Close the housing by lowering the forward part of the housing (with the PCB)
from above over the rear panel. The latch mechanism on the underside must
engage with a clear "click".
Installation of the XS 1B-D control unit
The control unit is battery-powered and communicates wirelessly with the motor
control unit.
Avoid selecting an installation position in direct sunlight, as this will result in
incorrect indoor temperature measurements. The measuring sensor is built into
the underside of the control unit. For the same reason, the control unit should
not be installed above a radiator. Please also ensure that no direct draft from
windows or doors distorts the measurement values.
The control unit must only be installed and used in dry, interior
spaces. Relative air humidity must not exceed 80%. Avoid
condensation.
