Type of board connected
The chronothermostat can verify whether the base is connected. If it is not, the short lines
are displayed, whereas if it is connected the wording rEL appears. In the radio frequency
version, the writing rAd is displayed.
Temperature scale
Selects the scale, degrees Celsius (centigrade) or Fahrenheit, that will be used for display
of all the temperatures. If the Fahrenheit scale is used, the temperatures can range from
0.0 °F to 99.9 °F.
Type of regulation
Selects the mode of temperature regulation: with differential (Std) or proportional (ProP).
This parameter is used for heating only.
Thermal differential
Imposes the thermal differential when the mode of temperature regulation with differential
has been chosen. Choosing the differential appropriately, on the basis of the thermal
inertia of the heating plant, one avoids continuously switching on and off (hunting). The low
thermal differential (LO) is recommended for heating plant with radiators, the high one (HI)
for plant with Fan-Coils.
Regulation band
Select the appropriate value according to the thermal gradient of the plant (wide band for
steep gradients – narrow band for low gradients).
