On power failures and ETS downloads, chrono-thermostat boxes behave
the same as other user-defined timers: the user configuration will not be lost,
although after an ETS download it will be necessary to enable the chrono-
thermostat manually.
Each chrono-thermostat box entails the following three objects:
• “[Pn][Bi] Chrono-thermostat: Enabling”: permits activating (value “1”)
or deactivating (value “0”) the chrono-thermostat analogously as from
the on-screen switch button of the box, which will show the icon
while deactivated.
• “[Pn][Bi] Chrono-thermostat: Temperature Setpoint”: this is the
object through which the timed temperature setpoints will be sent.
• “[Pn][Bi] Chrono-Thermostat: On/Off”: this is the object through which
the timed switch-off orders will be sent.
g) Alarm
Figure 81 Alarm
Boxes configured as alarms perform user warnings on anomalous events. For
this purpose, boxes of this type are related to a binary object ([Pn][Bi] Alarm
Trigger) that permits receiving alarm messages from the bus, thus making
Z41 Lite emit a continuous beep while the screen light blinks. In addition, the
screen will automatically browse to the page containing the alarm box that has
been triggered. After that moment, pressing on any button of the screen will
interrupt the beeps and blinks although the box will still show an intermitting
icon, which means that the alarm is still active and unconfirmed. Additionally,
the icon of the page that contains the box will also show an exclamation.
