VALVES
The valve control of the fan coil module entails a
scaling algorithm
of the input control
signals (or
ICS
), i.e., the percentage control variables for heating and for cooling that
are received from the thermostat, which itself may be external or any of the thermostats
incorporated in MAXinBOX FC 0-10V VALVE.
The result of the scaling algorithm and of the application of any other required
restrictions makes up the output control signals (or
OCS
), i.e., the percentage control
values (or 0-10V signals) that will govern the valves.

Fan Coil – Control signal scaling.
This scaling algorithm can be widely customised by the integrator, being possible to
define for each of the modes / valves:
An
effective input range
(i.e., the minimum and maximum values of the
ICS),
An
effective output range
(i.e, the minimum and maximum values of the
OCS),
In addition, the valve control can be customised through the following options:
A
minimum spacing
between successive OCS orders,
A delay in the
mode switchovers
,
The
minimum valve opening
level.
