Mod
Defines if thermostat will operate with On-Off control (000) or with Auto adapt PID (001).
In On-Off mode heating commissioning output is activated when temperature drops
below setpoint at least as minimum as dt (differential).
In Auto Adapt PID mode thermostat activates or deactivates the heating or cooling
system based to repeated commissioning cycles with duration equal to HCT. Auto Adapt
PID can achieve more accurate temperature control and thus greater economy. HCT
parameter should be adjusted prior to Auto Adapt PID mode use.
TRI
Temperature reading correction parameter. Temperature reading value can be altered
+/-5°C. To utilize that function select that parameter and adjust the value so as to show
the correct temperature.
dT
Differential. Applicable only in On-Off mode (Mod=000).
SHi
Maximum setpoint limit.
SLo
Minumim setpoint limit
Pbn
Proportional band. Applicable only in Auto Adapt PID mode (Mod=001).
HCT
Time indicating the heating or cooling cycle. Enter values from 10 to 15 minutes for
systems vulnerable to frequent activations or having big thermal inertia. Use smaller
values for others.
STP
Integral step. Applicable only in Auto Adapt PID mode (Mod=001). This value is
automatically adjusted when parameter HCT is altered. It is also possible to be adjusted
separately. The bigger the value of the STP parameter the slower the temperature
correction performed by the thermostat. Excessively small STP values can lead to
opposite control result or even loss of control.
RST
Select this parameter in order to restore all values to the factory preset setting.
