TWO POINTS 0%-100%
The operating principle is similar to that of the two points ON-OFF, but with the difference
that the communication objects for temperature adjustment management are of 1 byte.
In heating mode, when the detected temperature is lower than the “setpoint -
heat
”
value, the device activates the heating system by sending the relative percentage command to
the actuator that manages it; when the detected temperature reaches the fixed setpoint value, the
device deactivates the heating system.
H
EATING
In cooling mode, when the detected temperature is higher than the “se
cond
” value,
the device activates the cooling system by sending the relative percentage command to the
actuator that manages it; when the measured temperature reaches the fixed setpoint value, the
device deactivates the cooling system.
C
OOLING
To avoid the continuous switching of the solenoid valve, after a 0%-100%-0% sequence,
the next 100% command can only be sent after at least 2 minutes have elapsed.
Setting the adjustment differential
Use the
button keys to set the value of the adjustment
differential of the two-point control algorithm (the gap can
be set from 0.1°C to 2.0°C).
To confirm your choice and move on to the next parameter,
press the
button key within 30 seconds.
