TECHNICAL DATA OF THE CHRONOTHERMOSTAT
Operating temperature: -0°C +50°C
Humidity: 95% maximum at 40°C
Power supply: low voltage (3V), obtained from communication with the boiler control board
Protection degree: IP30
Dimensions: 140x90x32 mm
Compliance: directive 2004/108/CE (EMC), directive 2006/95/CE (LVD).
Temperature controls classes in accordance with the delegated regulation (EU) No 811/2013:
Class 1, FIAMMA OT11 used in ON/OFF operation.
Class 5, FIAMMA OT11 used in modulating operation. Class 6, FIAMMA OT11 used with outside temperature compensation.
Weight: 170 g
The digital chronothermostat FIAMMA OT11 series integrates the functions of room temperature control and remote control of home heating system in a single interface, specially designed to make available all its functionalities in intuitive mode.
Control of the heating system is complete, allowing to manage advanced features such as solar thermal panels (if supported by the thermoregulation board).
It is possible to choose between different modes of thermoregulation, even using an external probe (connected to the boiler) for climatic compensation.
Weekly programming is particularly versatile because it provides 4 temperature levels settable and no restriction number of time slots per day, consisting of individual intervals equal to a quarter of an hour and can be viewed on the appropriate graph of the daily program.
The communication between the thermostat and the control board of the boiler takes place by means of a two-wire cable; the data are exchanged with the communication protocol compatible OpenTherm TM v3.0 Smart Power Mode – Medium Power.
PLEASE NOTE: This will work with any Elektra boiler with serial number 77377 and onwards
