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 period + 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 configuration
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.
