Type of connected card

The chronothermostat can check whether the base is connected. If it is not 
connected dashes will be displayed whereas when it is connected the writing 
rEL is displayed. 

Temperature scale

To select the temperature scale to be displayed: Celsius (centigrade) or 
Fahrenheit. When choosing the Fahrenheit scale, temperatures may range 
between 0.0 and 99.9 °F.

Type of regulation

To select the temperature regulation mode: differential (Std) or proportional 
(ProP). This parameter is used for heating only.

Thermal differential

To set the thermal differential value to be used when choosing the differential 
temperature regulation mode. Continuous switching on and off can be avoided 
by choosing a proper differential value according to the thermal inertia of 
the heating system. It is recommended to set a low thermal differential (LO) 
in heating systems with radiators and high thermal differential (HI) in heating 
systems with fan-coils.

Regulation band

To select the proper value according to the thermal gradient of the system 
(broadband for high gradients– narrow band for low gradients).

Regulation period

To set the regulation cycle length (ON  OFF period) when the proportional 
temperature regulation mode is chosen. Select 5 minutes for low-inertia systems 
(fan-coil type), 10 minutes for average-inertia systems (aluminium radiator type) and 
20 minutes for high-inertia systems (cast-iron radiator type).

External temperature probe configuratio

n

The chronothermostat may be connected to a an external temperature probe. 
Probe operation is determined by this parameter.

• 

Probe off (---): the temperature value detected by the probe is not used
(although the probe is connected).

•  Floor probe (FLO): when the temperature detected by the probe reaches the 

value set in the Floor temperature limit parameter, the system will be turned off
regardless of the temperature read by the chronothermostat.

Floor temperature limit

To set the temperature limit value read by the external probe which turns the 
system off when the floor probe is used (for floor heating systems).

Ambient temperature correction

To sum/subtract an offset value to/from the temperature value read by the 
chronothermostat.
