TEMPERATURE ADJUSTMENT METHODS
TYPE
The
thermostat is factory set to work in
programmable
THERMAL
DIFFERENTIAL
ON/OFF
mode
with a preset
differential value
thermal
(Hysteresis) of 0,3 °C.
Note: adjustable from 0,2 °C to 1,2 °C
(from 0,3 °F to 2,1 °F).
The hysteresis value must be set according to the system's thermal
inertia; a low value is recommended for systems with radiators made
of e.g. cast iron and a high value for systems with fan coils.
As opposed
to the
differential, the temperature can be adjusted
thermal
MODULATING PROPORTIONALLY (PROP)
setting cycles from 7 to 20
minutes (default 10 minutes).
This system maintains the desired temperature more stable, whilst
increasing the user's comfort sensation and saving on energy
consumption.
A long cycle is recommended for systems with high thermal inertia
(cast iron radiators, floor systems) and a short cycle for systems with
low thermal inertia (fan coils).
