ADDITIONAL INDICATORS
KLIC-DA LT does monitor other information received from the Altherma LT system, and
therefore is able to report it to the KNX bus:
Temperatures
(an external temperature or that of the DHW tank, the output
water flow, the input water flow or of the refrigerant).
State of the actuators
(pump, compressor, backup heaters…).
Additional information
(water flow, electrical consumption to date, energy
production to date).
2.5
START-UP
Both user interfaces in the Altherma system (i.e., the main control and the additional
control) are powered from the P1/P2 bus. In addition, when the whole Altherma system
is switched on, the main control
collects information on the status of the installation and
then shares it with the additional control.
KLIC-DA, however, is powered from the KNX bus instead of the P1/P2 bus. Therefore,
it may initialise at a different moment than the main control, so it is advisable to restart
the Altherma system after installing KLIC-DA and downloading the application.
Notwithstanding the above, in order to guarantee consistency between the actual
status of the system and that of the communication objects sent to the KNX bus (
which
will not lose their values after a power failure
), whenever KLIC-DA establishes
communication with the main control, it will send the appropriate commands so the
Altherma system switches to the last status the domotic system is aware of.
1. Once KLIC-DA gets at least one valid frame from the Altherma system, KLIC-
DA will send a reset order (it will have no effect if the Altherma system is
already running the initial communication sequence).
2. During the initial communication sequence (~30 seconds), the main user control
will show the word “Busy”.
3. A few more seconds after the initial communication sequence, KLIC-DA will
send the proper orders to switch the Altherma system to the status it was aware
of prior to the power failure (or to the factory defaults, on the very first start-up).
