Any control order is
ignored
, but taken into account after leaving this mode.
The forced position resumes after a
power failure
.
An
Off order
will be performed as usual, and leads to leaving the forced
position mode.
Upon the reception of
On order
, the fan control order will be sent again, as
well as the On status, but there will be no action on the valves.
The pre-set output value for this mode does not depend on the
offsets
, being
up to the integrator whether to set a value greater than Offset 1.
Mode switch orders
are not executed until the forced position mode is left,
although they are responded by sending the mode status object.
If the
fan coil module is off
, forced position orders are ignored.
Finally, it is possible to
enable fan speed manual control
during the normal operation
and when the valve is closed in cooling mode. There are the following objects related
to this functionality: enabling / disabling manual control object and its status and the
manual control variable object (which will be applied to the fan speed).
The manual control orders will be ignored if:
The fan coil is off.
The fan coil is on but the valve is closed.
There is an exception in this case: if the option to
keep the fan activated in
cooling mode when valve closes
is enabled, the manual control orders will
be applied, instead of the value set by parameter (see Figure 12
, “Speed in
cooling mode”).
Force position is active.
The control orders are sent during any delay.
Furthermore, it is possible to establish the
duration of manual control
, i.e., the time to
reactivate the automatic mode. This time is reset when a new control order is received,
when turning the fan coil off and on or after a bus failure.
