The device can be configured with the ETS software, to perform the following functions:
Temperature control
• at 2 points, with ON/OFF commands or 0%/100% commands;
• integral proportional control, with PWM commands or continuous adjustment (0% 100%).
Fan coil management
• fan coil speed control with ON/OFF selection commands;
• management of 2way or 4way systems, with ON/OFF commands or 0%/100% commands.
Operating mode setting
• from the BUS, with distinct 1bit objects (OFF, ECONOMY, PRE-COMFORT, COMFORT);
• from the BUS, with a 1byte object.
Operating Setpoint setting
• from the BUS, with a 2byte object.
Temperature measurement
• with a built-in sensor;
• mixed built-in sensor/external KNX sensor/external NTC probe sensor with definition of the relative
weight.
Measuring relative humidity
• reception of the relative humidity measurement from an external KNX sensor;
•
setting of up to5 relative humidity thresholds, with BUS commands sent when the threshold is
exceeded and restored:
- 1 bit, 2 bit, 1 byte commands to act on the humidification/dehumidification system;
- HVAC mode commands to act, upon feedback, on the heating/cooling system;
- set-point values to act, upon feedback, on the heating/cooling system;
• calculation of specific humidity;
• indication of the thermal well-being status.
Underfloor probe
• setting of threshold value for floor temperature alarm.
Temperature control for specific zones
In "Slave" control mode:
• with the operating mode received by the Master device, and the use of a local Setpoint;
• with the Setpoint value received by the Master device, and local residual current device for
temperature.
In "autonomous" control mode:
• with local selection of operating mode and Setpoints;
• with local selection of operating Setpoint.
scenes
• storage and activation of 8 scenes (value 0..63).
Other functions
• setting of the Setpoint (OFF, ECONOMY, PRE-COMFORT, COMFORT) from the BUS;
• setting of the operating setpoint from the BUS;
• setting of the type of operation (heating / cooling) from the BUS;
•
transmission of the status information (mode, type), measured temperature and current Setpoint
on the BUS;
• management of the status information arriving from the commanded actuator;
• management of the status signalling window for temporarily switching off the thermostat;
• auxiliary input for fronts management, brief/prolonged operation, dimmer with single or double
push-button, roller shutters with single or double push-button, scenes and window contact;
• logic operations AND/NAND/OR/NOR/XOR/XNOR up to 8 logic inputs;
• management of display parameters.
