programming unit.
Standard unit:
■ ON/OFF switch
■ Terminals for high limit safety cut-out test
■ Keys for emissions test function
■ Optolink laptop interface
■ Temperature controller
DIN TR 96808
or
DIN TR 116807
■ High limit safety cut-out
DIN STB 106005
or
DIN STB 98108
or
DIN STB 116907
■ Operation and fault displays
■ Plug connection chamber
– Connection of external equipment via a system plug
– Connection of three-phase consumers via additional contactors
Programming unit:
■ With digital time switch
■ Backlit display with plain text user prompts
■ Adjustment and display of temperatures and codes
■ Fault message display
■ Rotary selector for the temperature in standard mode
■ Keys:
– Temperature for reduced mode
– Program selection
– Holiday program
– Party and economy mode
– DHW temperature
– Heating curves for boiler water temperature and flow temperature
– Heating circuit selection
– Time / Date
Functions
■ Weather-compensated control of the boiler water and/or flow tem-
perature
■ Electronic maximum and minimum temperature limit
■ Demand-dependent heating circuit pump and burner stop (not for
burners on boilers with a low-end boiler water temperature limit)
■ Adjustment of a variable heating limit
■ Anti-seizing pump protection
■ Integral diagnostic system
■ Flue gas temperature monitoring with flue gas temperature sensor
■ Maintenance display
■ Adaptive cylinder temperature control with priority control (heating
circuit pumps off, mixer closed)
■ Auxiliary function for DHW heating (short-term heating to a higher
temperature)
■ Optimised control of a heating circuit, e.g. underfloor heating circuit,
via a flow and return temperature sensor
■ Screed drying, for underfloor heating systems
