C820RQ - LED THERMOSTAT
ADVANCED FUNCTIONS
The C820RQ is a room thermostat that allows temperature setpoint adjustment in ON/OFF or TPI mode.
OPTIMISATION
When the thermostat is set with ON/OFF control, this function allows the required setpoint temperature to be reached by
acting on the on/off times of the heating/cooling system according to the type of system installed and the set differential,
minimising the energy consumption of the system itself.
TPI LOGIC (Time Proportional & Integral control)
If the thermostat is powered by 230V mains, 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 system switch-on time.
Depending on a number of settable parameters, such as the energy class of the flat, the type of emission terminal, the
proportional band, the control period and the room temperature, the thermostat optimises the system's running time with
proportional and integral action.
The output is always a single contact but time-controlled. As the room temperature reaches the setpoint temperature, the
switch-on time of the thermostat in each period decreases. In this way, the TPI control reduces boiler starts and maintains a
more constant comfort level around the required setpoint. This translates into greater 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 for temperature correction
- 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
- Data displayed on the homepage
- ON/OFF - TPI control function
- Optimisation for ON/OFF function
