P19: This parameter sets the hysteresis value (in °C or °F) applied when driving the on-off  
outputs in response to variations in the room temperature.  
P20: If the thermostat is configured to operate with a neutral zone, this parameter determines  
the amplitude of the neutral zone. This value is assumed to be central with respect to the  
set-point temperature.  
P21: This parameter may be used to define a delay time (in seconds) between the moment  
the fan is switched on and the moment the valve is opened, so as to allow sufficient time for  
the heat exchanger to heat up or cool down.  
P22: This parameter may be used to define a delay time (in seconds) between the moment  
the fan is switched on and the moment the valve is closed, so as to allow sufficient time for  
the heat exchanger or heating element to dissipate all its heat.  
P23: This parameter defines the threshold above which the supply water is considered suf-  
ficiently hot to implement the “minimum temperature thermostat” function in heating mode.  
If this function is not required, set this parameter to zero.  
P24: This parameter defines the threshold below which the supply water is considered suffi-  
ciently cold to implement the “minimum temperature thermostat” function in cooling mode.  
If this function is not required, set this parameter to 99.  
P25: This parameter defines the “Dirty filter warning” interval and may be set to any value  
between 0 and 50 x 100 h, in other words, if the value is set to 10, the warning will be gen-  
erated after 1000 hours.  
Set the value to 0 to disable the “Dirty filter warning”.  
DESCRIPTIONOFEXTENDEDCONFIGURATIONPARAMETERS  
The extended installer configuration parameters are shown in table 2 and explained below.

C03 and C04: These parameters may be used to define the amplitude of the proportional  
band, in heating and cooling mode respectively.  
The parameters can be set to a value within the range shown in table 2, however, due to the  
hysteresis value set-up in P19, the lower limit may be higher, since the two parameters interact.  
C05 and C06: These parameters may be used to set the integral regulation time in heating  
and in cooling mode respectively.  
If these values are set to zero, no integral action is implemented.
