The Valve(s) screen (see Figure 12) is accessible by default after enabling the fan coil
module. It contains the following parameters:
CONTROL SIGNAL SCALING
Minimum of the ICS (from Thermostat)
: sets the minimum value of the
input signal, in terms of percentage,
that is desired
to make the valve open.
For lower values, the valve will be left closed. The default value is “0%”.
Maximum of the ICS (from Thermostat)
: sets the maximum value of the
input signal, in terms of percentage,
that is desired
to make the valve keep
opening. Input values greater than this will be ignored as the valve is
considered already open. The default value is “100%”.
Minimum of the OCS (to Actuator)
: sets the minimum voltage or value of
the output signal, in terms of percentage,
that causes
the valve begins to
open (lower voltages have no effect on the valve). This is valve-specific. The
default value is “0%”.
Maximum of the OCS (to Actuator)
: sets the maximum voltage or value of
the output signal, in terms of percentage,
that causes
the valve keeps
opening (greater voltages have no effect on the valve). This is valve-specific.
The default value is “100%”.
The above four parameters are available
for each valve
(in case of having two valves).
Notes
:
Please ensure to set minimum values that are lower than the maximum
values.
This scaling does not apply to other functions with a higher priority, such as
Alarms and Purge (please see Annex I: Fan Coil Priorities)
.
CONTROL SIGNAL CHANGE LIMITS
Minimum Change Between Two Successive OCS Orders
: sets the
minimum change of the OCS (in terms of percentage, between 0% and 10%)
that should make the device actually operate the valve (local control) or
update the valve control objects (remote control). This prevents continuous
operation of the valve in case the OCS changes frequently.
