when choosing the differential temperature
regulation mode. Continuous switching on and
off can be avoided by choosing a proper differ-
ential 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 gra-
dients).
Regulation period
To set the regulation cycle length (ON period
+ OFF period) when the proportional tem-
perature regulation mode is chosen. Select 5
minutes for low-inertia systems (fan-coil type),
10 minutes for average-inertia systems (alu-
minium radiator type) and 20 minutes for high-
inertia systems (cast-iron radiator type).
Separate temperature probe confi guration
The chronothermostat may be connected to a
separate temperature probe. Probe operation
is determined by this parameter.
•
Probe off
(---): the temperature value de-
tected 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 tem-
perature read by the chronothermostat.
•
Ambient probe
(In): system regulation is
based on the temperature value detected by
the separate probe. This temperature value is
displayed instead of the temperature value de-
tected by the internal probe of the chronother-
mostat. The separate ambient probe is used
when the chronothermostat is necessarily lo-
cated in a room other than the one the tem-
perature of which is to be controlled;
•
External probe
(Out): has no effect on sys-
tem regulation, it is just used to know another
temperature, e.g.: the outside temperature.
Floor temperature limit
To set the temperature limit value read by the
separate probe which turns the system off
when the
fl oor probe is used (for fl oor heating
systems).
