INSTRUCTIONS FOR USE OF THE ELECTRONIC THERMOSTAT
(Fig. C)
The electronic control consists of a thermostat that allows you to choose the ambient temperature from 7°C to 35°C.
INSTRUCTIONS FOR USE AND OPERATION
1. PRESENTATION
The electronic thermostat has 4 buttons and 1 display (Figure 1). The electronic thermostat is started by pressing the [ON/Standby] button: when the
electronic thermostat is in standby, the flashing letters “St by” appear on the display; when it is in the chrono modes, the program appears with the
indication of the time or the number of the selected integrated program (P1, P2, P3), or the setting of the mode temperature.
2. STAND-BY OPERATION
When changing from STAND-BY to one of the operating modes, the electronic thermostat emits a sound lasting 1 second.
Vice-versa, when changing from one of the operating modes to STAND-BY, the electronic thermostat
emits two short sounds with a pause of half a second between them.
When it is powered, the electronic thermostat emits a warning sound to indicate its status according to the
logic described above.
Next to the display is a coloured bar: an arrow on the display indicates one of the three colours depending
on the current temperature setting, as in the table below. This indicator provides a visual indication that
setting high temperatures results in a higher energy consumption.
3. DESCRIPTION OF USE
The electronic thermostat has 8 operating modes: 1 pre-set free chrono program, 3 integrated chrono programs, pilot-wire, comfort, night and
antifreeze. To change from one mode to another, press the FUNCTIONS button

Operating mode description
CHRONO
Follows the weekly programming on two temperature levels (high and low) defined by the user hour by hour.
All the PILOT-WIRE controls are disabled except STOP.
P1 FIXED
PROGRAM
+
P1 fixed weekly program (working week program) on two temperature levels (high and low) pre-defined time hour by
hour.
All the PILOT-WIRE controls are disabled except STOP.
P2 FIXED
PROGRAM
+
P2 fixed weekly program (working week program) on two temperature levels (high and low) pre-defined time hour by
hour.
All the PILOT-WIRE controls are disabled except STOP.
P3 FIXED
PROGRAM
+
P3 fixed weekly program (working week program) on two temperature levels (high and low) pre-defined time hour by
hour.
All the PILOT-WIRE controls are disabled except STOP.
PILOT-WIRE
The locally set high temperature is modified according to the controls received from the Pilot-Wire unit, except in the
case where the Pilot-Wire is not connected, or with class 1 regulators (products with an earth connection).
The ELECTRONIC THERMOSTAT recognises 6 controls: comfort, reduction (high temperature -3.5°C), stop,
antifreeze (7°C), eco1 (high temperature -1°C) and eco2 (high temperature -2°C)
COMFORT
Regulation without time limits on the high temperature level.
All the PILOT-WIRE controls are disabled except STOP.
NIGHT
Regulation without time limits on the low temperature level.
All the PILOT-WIRE controls are disabled except STOP.
ANTIFREEZE
Regulation without time limits on 7°C.
All the PILOT-WIRE controls are disabled except STOP.
Two different temperature levels can be set, high and low. High temperature is used in the chrono modes, P1, P2, P3, Pilot-Wire and comfort. Low
temperature is used in the chrono modes, P1, P2, P3 and night. High temperature can be modified in comfort mode while low temperature can be
modified in night mode using the [+] and [-] keys. The flashing thermometer symbol indicates that modification is in progress. During modification, the
high temperature can be decreased to the current low temperature value and, vice-versa, the low temperature can be increased to the current high
temperature value.
IMPORTANT: changes in the ambient temperature are normal when using electronic thermostats when there are variations in the power requested or
when the environmental conditions change outside the room that is to be heated. The set value is correct only for radiators installed in standard
environments. It is normal for the regulator setting to be different to obtain the same temperature in different environments (influence of the
surrounding environment).
In chrono mode the temperature levels are used as illustrated in figure 3.
