Speed V1 is activated when the temperature value is lower than the “set-point -
valve
-
1heat
” value (in heating mode) or higher than the “set-point +
valve
+
1cond
” value
(in air-conditioning mode), and deactivated when the temperature value reaches the “set-
point -
valve
” value (in heating mode) or the “set-point +
valve
” value (in air-conditioning
mode). The first speed is also deactivated when a higher speed needs to be activated.
Speed V2 is activated when the temperature value is lower than the “set-point -
valve
-
1heat
-
2heat
” value (in heating mode) or higher than the “set-point +
valve
+
1cond
+
2cond
” value (in air-conditioning mode), and deactivated when the temperature
value reaches the “set-point -
valve
-
1heat
” value (in heating mode) or the “set-point
+
valve
+
1cond
” value (in air-conditioning mode). The second speed is also deactivated
when a higher speed needs to be activated.
Speed V3 is activated when the temperature value is lower than the “set-point -
valve
-
1heat
-
2heat
-
3heat
” value (in heating mode) or higher than the “set-point +
valve
+
1cond
+
2cond
+
3cond
” value (in air-conditioning mode), and deactivated
when the temperature value reaches the “set-point -
valve
-
1heat
-
2heat
” value (in
heating mode) or the “set-point +
valve
+
1cond
+
2cond
” value (in air-conditioning
mode).
With regards the heating (air-conditioning) solenoid valve, you can see that once the detected
temperature is lower (higher) than the “set-point -
valve
” (“set-point +
valve
”) value,
the timed thermostat sends the activation command to the solenoid valve that manages the
heating system; the solenoid valve is deactivated when the detected temperature reaches
the fixed set-point value. In this way, the heating (air-conditioning) of the fan coil can also be
exploited for irradiation, without any speed being activated.
To avoid continuous switchovers, the timed thermostat can wait up to 2 minutes before
sending the activation command to the actuator that controls the temperature adjustment
system, or to the actuator channels that command the fan coil speeds.
Setting the valve adjustment differential
Use the
button keys to set the value of the adjustment
differential of the fan coil valve control algorithm (the gap can be
set from 0,1°C to 2,0°C). If the control logic is common, the
parameter remains the same in both heating and air-conditioning
mode. To confirm your choice and move on to the next parameter,
press the
button key within 30 seconds.
