Keyboard ■ The keys carry out different functions on the basis of the instrument status and they will be described step by step in this user manual. Multipurpose keys are not built into the instrument, that is to say contemporary pressures of 2 or more keys. - Page 8 3. Upon receipt of the configuration string, the remote actuator is configured and resumes the normal operation while the Chronos RF requires date and time insertion ( the programming keys will be active only after you have hooked the thermostat at the base) Note: to associate a second remote actuator, activate the configuration of the actuator channel and, while this last is in configuration mode, remove the thermostat from the base and re-put it (the cronothermostat starts the...
- Page 9 • Clock setting Once the instrument is mains powered, set the clock (time and date insertion). The parameters to enter are the following: seconds (only synchronisation at value 00), minutes, hours, year, month, day. Use the keys to increase and decrease the values and the key confirm and to move to the next parameter.
- Page 10 HOUR TEMPERATURE At this point the chronothermostat will begin to operate with the set default parameters (see page 33) displaying the day of the week, the time, the environment temperature and the graphic of the program on.

5. Once all parameters are set, to exit and to go back to the programming menu, press for a short time the key To exit and to go back to the normal operation (automatic, manual) press for a long time the key or wait for the time-out expiration (30 seconds about). -
Page 17: Operating Mode
Operating mode This parameter allows to specify the operating mode of the chronothermostat, between winter-heating ( ) and summer-cooling ( For further information about the operating mode see the chapter “Regulation types” on page 24. Regulation type (only for heating mode) For heating mode it’s possible to choose between on/off regulation (Reg 0) or proportional (rEg P) or proportional programming (reg tP) to use if the remote actuator is a valve for ThermoPro RF radiators). -
Page 18: Regulation Parameters
Regulation parameters In case of on/ off regulation the only parameter to set is the hysteresis (dIF), which can have values between 0.1°C e 1°C. In case of proportional regulation the parameters to set are the regulation band (bnd) e il periodo di regolazione (PEr). - Page 19 If the key lock is active and one key is pressed, the display shows for a few seconds the writing bLoc with flashing dashes: enter the password to unlock the keyboard, which will be locked for 30 seconds from the last pressure. System operation hours This page shows the total number of hours of the system operation (relais ON) for the current mode...

Page 20: Manual Operation
MANUAL OPERATION During manual operation the instrument performs as a normal thermostat, adjusting on the basis of the Tm temperature (manual setpoint), independently from the day and the time where it is. The manual operation is signalled with the switch on of the symbol on field (5). -
Page 21: Off Operation
OFF OPERATION In off mode the instrument doesn’t perform any regulation (*) but it continues to display the day, the time and the measured temperature. (*) When in heating / winter mode the instrument maintains a minimum temperature - Toff antifreeze temperature - to avoid the freezing of the systems where the instrument is installed. -
Page 22: Minimum And Maximum Value
MINIMUM AND MAXIMUM VALUE It’s possible to display the measured values of minimum and maximum temperature. To display these values press the key (maximum value Hi) or (minimum value L0). During the display it’s possible the resetting of these values pressing the key until 3 dashes appear in place of the temperature. - Page 23 long time the key until the display shows the writing Aut0 appears on field (3). 3. Choose with the key automatic time change activation (Aut0 0n) or its deactivation (Aut0 0FF) and confirm with the key 4. If 0FF we go back to the date/time change; if 0n the current setting for the passage to summer time is displayed (indicated with the symbol...

Page 24: Regulation Type
REGULATION TYPE The Chronos has got two types of regulation: • ON/OFF regulation During ON/OFF regulation the chronothermostat measures once a minute the environment temperature and it carries out the regulation on the basis of the following logic: heating mode cooling mode relay ON relay ON... - Page 25 to the setpoint value – band, the more the activation time will be predominant in comparison with the deactivation time; on the contrary, the more the measured temperature is next to the setpoint value + band, the more the deactivation time will be predominant in comparison with the activation time).

Page 26: Timed Manual
• Emergency regulation (for heating mode only) The instrument performs a regulation of emergency if an error occurs during the reading of the probe or in case of time loss. In case of probe error, if the antifreeze function is not deactivated, the instrument activates the load for 10 minutes every 4 hours. - Page 27 Timed off If in off status you set a timing, such off status will be maintained until the end of the timing; operation will then switched to the one active before the deactivation (automatic or manual). If you set a timing, the display shows the symbol Attention: the timing is calculated in minutes and for this reason if for example you set a timing of 3 days at 12:15 on Tuesday it will expire at 12:15 on Friday.

Page 28: Instrument Reset
INSTRUMENT RESET If you want to erase all performed settings and to recharge the default values, proceed as follows: 1. to switch off and to switch on the power of the chronothermostat (230 V versions) or to disconnect the time thermostat from the wall-mounted base and reconnect it (battery versions). -
