Figure 8 – Logic function XOR
For each channel, a parameter
Delay after bus voltage recovery
is available: this parameter represents the time
interval between the bus voltage recovery and the first reading of the input communication objects for evaluating
the logic functions.
The communication function representing the logic function output is sent on the bus on event of change;
alternatively, a cyclic sending can be set.
7 Room Controller
The room air temperature control is performed thanks to the intercept valve(s) on the heat exchange coil(s), with
an ON/OFF or PWM control algorithm. In order to control those valves, electrothermal actuators and/or
servomotors can be used
7.1 Control algorithms
The picture below shows the components of a common generic control system for ambient temperature. The
room thermostat measures the actual temperature of the air mass (T
eff
) and constantly compares it to the
setpoint value (T
set
).
