Specification
Design
The control unit comprises:
■ PCB
■ Digital display
■ Selection keys
■ Terminals:
– Sensors
– Solar circuit pump
– KM BUS
– Power supply (on-site ON/OFF switch)
■ PWM output for actuating the solar circuit pump

The standard delivery includes collector temperature sensor and cyl-
inder temperature sensor.
Collector temperature sensor
For connection inside the appliance
On-site extension of the connecting lead:
■
2-core lead, length up to 60 m with a cross-section of 1.5 mm
2
(copper)
■ Never route this lead alongside 230/400 V cables
Specification, collector temperature sensor
Lead length 2.5 m
IP rating IP 32 to EN 60529; ensure through de-
sign/installation
Sensor type Viessmann NTC 20 kΩ at 25 °C
Permissible ambient temperature
– Operation −20 to +200 °C
– Storage and transport −20 to +70 °C
Cylinder temperature sensor
For connection inside the appliance
On-site extension of the connecting lead:
■
2-core lead, length up to 60 m with a cross-section of 1.5 mm
2
(copper)
■ Never route this lead alongside 230/400 V cables
Cylinder temperature sensor specification
Lead length 3.75 m
IP rating IP 32 to EN 60529; ensure through de-
sign/installation
Sensor type Viessmann NTC 10 kΩ at 25 °C
Permissible ambient temperature
– Operation 0 to +90 °C
– Storage and transport −20 to +70 °C
In systems with Viessmann DHW cylinders, the cylinder temperature
sensor is installed directly into the threaded elbow in the heating
water return: see chapter headed "Specification" for the relevant
DHW cylinder, and chapter headed "Installation accessories".
Functions
■ Switching the solar circuit pump for DHW heating and/or swimming
pool water heating
■ Limiting electronically the temperature in the DHW cylinder (safety
shutdown at 90 °C)
■ Collector safety shutdown
Information regarding auxiliary function for DHW heating and
suppression of reheating by the boiler
Systems with Vitotronic control units with KM BUS offer optional sup-
pression of reheating by the boiler and auxiliary functions for DHW
heating.
Systems with other Viessmann control units offer only optional sup-
pression of reheating by the boiler.
For further functions, see chapter headed "Functions".
