PIR MS – Multi Sensor
Hardware: V3.0
Firmware: V4.4
Considerations about the operation:
1.
Do not put the Multi-Sensor directly exposed to
fluorescent lamps or light sources;
2.
The device to control via infrared, must be
unobstructed visual;
3.
Learning can be difficult or even impossible because
of the light emitted by fluorescent lamps that are in
the vicinity of Multi-sensor. Should turn them off
when you want to learn a command IV;
4.
The Pir-Ms supports most protocols used in remote
controls, however it is possible that there is a specific
remote control that can’t be interpreted;
5.
Ability to memorize and reproduce Outputs Infrared
up to 640 bits of data;
6.
Ability to memorize and recognize Inputs Infrared up
to 256 bits of data;
7.
Automatic functions for AC may get to work
unproperly. This is because the replicated command
by Pir-Ms contains always the same time when the
remote control command is learned and the AC unit
could take this time as the correct.
Warnings on the volume control:
The module PIR-MS has the memorization features 20 single
function keys and not a repeating function. Moreover these
functions are not always present in the infrared remote
controllers. The increase in volume or other similar function
should be done by pulses (by pressing the key repeatedly).
The explanation for this behavior is that the PIR-MS is not a
simple command receiver for audio or adjustable values but
an infrared receiver for any type of remote controlled device.
Warnings in control of air conditioners:
Most air conditioning systems, use complex remote
controllers, and when sending a set-point (Ex: Change of
temperature), it is also sent the time and date that is set in the
remote's LCD. Thus learning functions such commands, in
most cases, can lead to unexpected changes in these
systems, eg sending the date and time it was "learned" this
function when creating.
