5.2. INPUTS
ZAS has two A/D inputs that can be configured as:
Switch/Sensor
A Switch/Sensor connected to an input, consists of an electrical mechanism
which may have its contacts open or closed under normal conditions. These
mechanisms do not recover their normal position automatically as with the push
button.
A transition of a digital signal from low to high or high to low is called "Edge".
9
Falling Edge
: closed contact to open contact.
9
Rising Edge
: open contact to closed contact.
When selecting an input as Switch/Sensor, the 1-bit object
“[Switch/Sensor]
Sensor Edge”
will be sent to the bus every time a falling or rising edge takes place
(with the corresponding configured value by parameter).
This type of input allows configuring a
delay
for sending the communication
object as well as a
cyclical sending
and an
automatic status sending
after a
power failure.
Temperature Sensor
A temperature sensor provides the real temperature measure of a room or
place.
The ZAS application program allows configuring both inputs as temperature
sensors and, in the menu
Thermostat
, the measure provided by these temperature
sensors can be mixed and set as temperature reference for the thermostat.
When configuring an input as temperature sensor, the temperature
calibration
,
the temperature
sending period
, the minimum
temperature change for sending
the temperature value to the bus can be established.
Moreover
freezing and overheating protection
can be enabled.
5.3. BUTTONS
ZAS has
8 tactile buttons
for general use,
two arrow-shaped buttons
(temperature control and scrolling) and two buttons for accessing the
Menu
and
validating the selected options (
OK
).
The 8 buttons for general use, located in 4 rows, can be configured in the following
way:
