With constant, digital boiler and heating circuit control for heating systems with one heating circuit without mixer and without low loss header. Prepared for the connection of a room temperature controller (accessory) for room temperature-controlled operation. Adjustable flow temperature for heating operation, demand-dependent heating circuit pumps and burner shutdown.

With weather-compensated, digital boiler and heating circuit control for operation with modulating boiler water temperature. For heating systems with a directly connected heating circuit without mixer and/or in conjunction with an extension set for 1 or 2 heating circuit(s) with mixer (included in package or as an accessory). An extension (accessories) is required for the heating circuit (without mixer) with low loss header and heating circuit pump. With 2 pump outlets for 1 storage tank loading pump (connected at the factory), 1 secondary heating circuit pump or 1 drinking water circulation pump (depending on the hydraulic scheme).

Periods for the heating circuits, drinking water heating and drinking water circulation can be set separately. Adjustable cycle operation for drinking water circulation. With storage temperature control. Increased drinking water hygiene possible by heating to an increased drinking water temperature setpoint. With automatic summer/winter time changeover, integrated diagnosis system, maintenance notification and controlled screed drying with effect on all heating circuits. Settings for operating modes, longer warm-up operation, holiday program, holiday-at-home program, chimney sweep test, demand-dependent heating circuit pumps and burner shutdown, as well as summer economy mode and variable heating limit. Possibility to set the room temperature (3 room temperature levels), the drinking water temperature and to query temperatures.

Integrated water pressure sensor for measuring the system pressure with adjustable system flow temperature setpoint and diagnostics.

Simple operation via 7-inch gray scale touch display with plain text support, large font and high-contrast display as well as context-related help.

Capable of communication via CAN-BUS, PlusBus, WLAN and low-power radio. Communication module integrated in the device. Remote control and monitoring of the device via smartphone with the ViCare app possible in connection with an integrated internet interface and on-site internet access via WLAN. Connection of an external operating program with an effect on all heating circuits or external blocking via an extension as an accessory via PlusBus possible. External specification of temperature set value (variable) via 0 to 10 V interface (accessories) and locking of external exhaust air devices possible. The WAGO Gateway (accessory) can be connected via the Viessmann CAN data interface. Data can be exchanged between the device and an external control system via the WAGO Gateway via one of the following data interfaces: KNX/TP, Modbus RTU or Modbus TCP. For weather-compensated operation Connection of wired Vitotrol 200-E remote control or Vitotrol 300-E remote control and connection of extensions with PlusBus communication possible. Device contains system switch, electronic maximum temperature limiter, temperature monitor and temperature limiter, operating and fault display.
