Lightly press
SET TEMPERATURE
on the display (Fig. 21) and keep it
pressed for about 3 seconds to change the
TEMPERATURE
DIFFERENTIAL
(d.t.) during the
PROGRAMMING
phase (Fig. 15B).
The writing “
dt
” will be shown on the display and the digits below will refer
to the temperature differential currently set in connection with the related
program (Fig. 16C).
It is therefore possible to set the temperature differential within a range of
0.2°C÷2.0°C by pressing the following keys: and .

FROST PROTECTION FUNCTION
The
FROST PROTECTION FUNCTION
remains on when the
thermostat is switched off.
If the detected temperature falls below 7 °C (7°C - 0.2°C=6.8°C), the
device activates a system which keeps water circulating and prevents it
from freezing inside the pipes. (Fig.17).
In the
WINTER
program ( ), the thermostat activates the heating
system when the following temperature is detected in the room:
SET TEMPERATURE - TEMPERATURE SEMI-DIFFERENTIAL
The heating system is switched off when the following temperature is
detected in the room:
SET TEMPE TEMPERATURE DIFFERENTIAL
Vice-versa, in the
SUMMER
program ( ), the cooling and/or conditioning
system is activated when the following temperature is detected in the
room:
SET TEMPE TEMPERATURE SEMI-DIFFERENTIAL
The cooling and/or conditioning system is switched off when the detected
temperature is as follows:
SET TEMPERATURE – TEMPERATURE DIFFERENTIAL
The pre-set TEMPERATURE DIFFERENTIAL in the thermostat is
0.4 °C for the
WINTER
program ( ) and 0.8°C for the
SUMMER
program ( ). This means, for example, the following:
Program: WINTER ( )

The thermostat detects two discharge thresholds of the batteries.
On reaching the
FIRST THRESHOLD
the symbol of a
DISCHARGED BATTERY
(Fig. 21) appears and maintains unaltered the instrument’s functions (Fig. 18A).
On reaching the
SECOND THRESHOLD
the thermostat switches off, disenabling
the operation of the heating system and flashing the
BATTERY DISCHARGED
symbol (Fig. 18B). To reset the functions of the
T-Touch 503
thermostat it is
necessary to substitute the batteries.

The thermostat will then be switched on (ON) or off (OFF) according to
the
REMOTE
command and to the status of the thermostat itself.
The statuses are reported in the table shown below (Fig.20):
