Thermona THERM 20 TCXE.A
Code: 1041.8Product detailed description
Low-temperature wall-mounted boilers Thermona THERM 20 TCXE.A with continuous-flow DHW heating
TURBO version
Boiler features and functions:
- The new control electronics are designed with an emphasis on increased user comfort, a display integrated directly on the board, and the replacement of mechanical parameter switches with software settings secured by an entry code, etc.
- The automation software has been updated and includes several patented solutions - e.g. a self-diagnostic system and fault evaluation
- The board design places emphasis on higher reliability of the operating elements
- The board includes a universal terminal block for both a room thermostat and an OpenTherm-communication controller (eliminating the need for the IU 02 unit)
- The electronics include both hardware and software for controlling a boiler cascade
- The software allows convenient service parameter settings via PC (authorised service only)
- The DIMS 01 automation monitoring and tester can still be used (different connectors - wiring adapter pieces required)
- For boilers with a tank, the software allows switching off domestic hot water (DHW) heating at the left end position of the DHW temperature control knob
- Possibility of connection to a solar system
Improved features of the new boilers:
- Suppression of EMC interference caused by the ignition spark and contact switching
- Pump operation control, fan operation control
- Flue gas discharge control by pressure switch or flue gas thermostat
- Power supply of the safety and flue gas thermostat by safe low voltage
- Provision of irreversible shutdown
- Smooth flame modulation with PWM current regulator
- Temperature control by PID-type regulation
- Heating temperature monitoring by an NTC temperature sensor (continuous-flow water heating boilers only)
- DHW temperature monitoring by an NTC temperature sensor
- DHW tank thermostat input (heating of an indirect tank)
- Communication with an external controller (OpenTherm) or cascade system (with IU04 and IU05 interfaces)
- Communication port for a desktop or laptop computer for boiler monitoring and setting of operating parameters
- Optional integrated weather-compensated control using an external temperature sensor
- Information menu for checking operating parameters
- Setting of boiler operating parameters (setup menu)
- Boiler configuration setting after entering an access code (setup menu 2)
- Fault detection via the history menu
- Three rotary controls for selecting the operating mode, the desired heating temperature and the desired DHW temperature (continuous-flow heating only)
- Monitoring of heating water flow, or pressure, by a flow/pressure switch
