The SimpleHome module 20046821 can be used to measure the power absorbed
or produced over a single-phase system with a voltage of 230 Vac. By installing this
module in the SimpleHome system and connecting it to the BUS, it will be possible
to view the power value measured by the module on one of the supervisors (e.g.
Planux Manager, Serial Bridge, Minitouch, etc.). In addition to simply recording
measurements, a list of loads can be set for the disconnection of digital outputs
on the SimpleHome modules (connected, for example, to controlled sockets) if
the recorded consumption value exceeds the limit set during programming. This
application is useful for ensuring the energy supplier's thermal switch is not
triggered. The outputs are disconnected in accordance with the specified order.
After a certain period of time (which can be programmed), the module will attempt
to reactivate the outputs in reverse order. An absorption value can be set for each
of the loads entered on the control, so that reconnection only occurs at the very
moment in which the power entered for that load is available on the system.
A SimpleHome system output can be set so that when the load control intervenes,
the output is activated to signal excessive consumption and indicate any downtime
caused by the disconnection of the outputs. It is also possible to set an instant
disconnection threshold on the module; when this is exceeded the module will
deactivate all specified outputs instead of disconnecting each output one-by-one
with the relevant control.
The module can be used to store information for the metering of recorded energy,
and functions as a log. The total sum of the recorded power values can be viewed
by entering several devices on a single system. For this function to work, a
compatible supervisor must be fitted to the system.
Operation example:
Timed disconnection limit: 3500 W. Instant disconnection limit: 4000 W. Load 1:
consumption 800 W, disconnection time 5 minutes. Load 2: consumption 1500 W,
disconnection time 5 minutes. When 3500 W is exceeded, the module will begin
by disconnecting load 1, followed by load 2. When the set disconnection time has
elapsed, the module will attempt to reactivate the load disconnected most recently.
If in that instant the module reads a value of 2500 W it will not reactivate load 2,
which has a consumption of 1500 W, to avoid exceeding the set disconnection limit
(3500 W); it will, however, reactivate load 1 as the consumption of this load will not
cause the limit to be exceeded. The module will then only reactivate load 2 when
sufficient power is available on the system.
Tolerance and hysteresis values must be taken into account, as they may cause the
readings to vary by approximately 100 W.
