C820RQ - LED THERMOSTAT
ADVANCED FUNCTIONS
C820RQ is a room thermostat that allows the temperature setpoint adjustment in ON/OFF or TPI modes.
OPTIMISATION
When the thermostat is set in ON/OFF, the required setpoint temperature can be achieved by acting on the on/off times
of the heating/cooling system according to the type of the installed system and the set differential, minimising the energy
consumption of the system itself.
TPI LOGIC (Time Proportional & Integral control)
If the thermostat is power supplied at 230V, the special TPI algorithm can be used. In this control mode, the thermostat
reaches the setpoint with accuracy and precision to maintain a more constant level of comfort, while guaranteeing the
shortest possible switch-on time.
According to a number of settable parameters, such as the energy class of the flat, the type of emission terminal, the
proportional band, the regulation period and the room temperature, the C820RQ optimises the system's working time with a
proportional and integral action.
The output is always a single contact but controlled over the time. As soon as the room temperature reaches the setpoint
temperature, the thermostat switch-on time decreases in every period. In this way the TPI control reduces boiler starts and
maintains a more constant comfort level around the required setpoint. This allows a better comfort and cost savings for the
end-user.
It is also possible to access two different menus for configuring certain parameters:
■ USER MENU
- Password setting
- Stand-by time
- Display light intensity
- Offset to correct the temperature
- Season (summer/winter)
- Firmware release version
■ ADVANCED MENU
- Winter season: minimum and maximum set point value
- Summer season: minimum and maximum set point value
- Antifreeze setting
