CONFIGURATION To make the association with an output module press keys and simultaneously, after having set the output module in learn configuration (see the relative instruction sheet). The actual transmission of a command is signaled on the display by the temporary swit- ching on of symbol , RF transmission. OPERATION The timer-thermostat operates in combination with a 3A or 16A output module in BISTABLE operating mode, sending switch on/switch off commands depending on its temperature regulation mode and the type of operation selected (heating or air conditioning). The timer-thermostat periodically retransmits the command, every 5 minutes, to the ombined actuator. If the actuator does not receive the message for 4 consecutive times, it commands opening of the relay (OFF) and signals the fault with the green LED blinking. SIGNALS Transmission of a command The transmission of an RF command (ON/OFF) is signaled on the display by the temporary switching on of symbol . Radio frequency communicationOPERATING INSTRUCTIONS

The timer-thermostat offers 3 different operating modes:: - AUTOMATIC - MANUAL - OFF/ANTIFREEZE Key is used to switch from one mode to another. In automatic operation the timer-thermostat uses a program that can be different for every day of the week. The text AUTO, the ambient temperature measured and the symbol of the set point relative to the current quarter of an hour appear on the display. In the hourly profile the column relative to the current hour blinks with the representation of the active set point. In manual operation the timer-thermostat permanently uses a temperature set point that can be freely set. The text MAN and the ambient temperature measured appear on the display. Antifreeze operation is only active in heating. In this case the timer-thermostat uses the set point of the ntifreeze temperature set. The text OFF and the ambient temperature measured appear on the display. Operating modesOPERATING INSTRUCTIONS

When operating, the activation of the heating or air conditioning is signaled as follows: Heating The symbol shows switching on of the heating.
