HEATING CONTROLS
The HeatingBOX actuator incorporates
four or eight outputs
, each of them capable of
controlling one or several heating valves at 24V or 230V.
The actuator provides a set of common options to configure the general operation of
these valves:
A
start-up delay
, to prevent performing control orders over the outputs
immediately after the device initialisation. Note that this start-up delay is
interrupted if alarm or lock orders (see section 2.4.1.1) are received.
Short-circuit, overload and all-valves-closed
notifications
, which are
periodically sent through specific one-bit objects in case such events occur:
Short-circuit
or
overload
: in case a short circuit or overload is detected on
a particular output:
HeatingBOX 24V
periodically reports both errors via a single
communication object.
HeatingBOX 230V
reports both errors independently. If a short circuit is
detected at an output, it will be periodically notified through a specific
object of that output, while overload error is reported jointly for outputs 1-
4 and 5-8, through an object per group.
In the event of any of the two errors, the current flow through the
corresponding output or group of outputs will be interrupted (the valve will
return to idle position) and the associated LED or LEDs will flash every
second. This status will be maintained until a new control order is received.
If 4 errors are detected in a 3 minutes period on any of the channels, the
device will lock all regulation for the next 3 minutes and the programming
LED will flash together with all the output LEDs. There will also be a status
object to notify the activation and deactivation of the lock.
All valves closed
: it may be significant for the climate system whether all
valves are currently closed or not (e.g., to switch off the climate unit in case
they are). This notification can be restricted for
a specific set of valves
(so
