The Vitotronic 100, type CC1E and type CC1I control
units are designed for the control of single boiler sys-
tems with a constant boiler water temperature.
The Vitotronic control unit is factory-configured as a
"Single boiler constant control".
During operation with a constant boiler water tempera-
ture, the boiler provides heating water at a constant
temperature, independent of the outside temperature.
In single boiler systems, central heating and DHW
heating are provided at a constant flow temperature.
The flow temperature corresponds to the set boiler
water temperature.
Alternatively, your contractor can configure the
Vitotronic control unit as a "Boiler in the Cascade".
The Vitotronic control unit is then used to control the
boiler water temperature of a boiler in a multi boiler
system.
Note
These instructions describe the Vitotronic 100,
type CC1E and CC1I for the following applications:
■
In a single boiler system
■
In a multi boiler system with a higher ranking third
party control unit (e.g. cascade control unit)
For multi boiler systems with Viessmann Vitotronic 300
cascade control units, you will find all the information
about operation in the "Vitotronic 300" operating
instructions.
Commissioning
The commissioning and matching of the control unit to
local conditions and building characteristics, as well as
instructing the user in the operation of the system,
must be carried out by your heating contractor.
As the user of new combustion equipment, you may be
obliged to notify your local flue gas inspector of the
installation [check local regulations]. Your local flue gas
inspector will also inform you [where appropriate]
about work he may be required to carry out on your
combustion equipment (e.g. regular checks, cleaning).
Your system is preset
Your heating system is preset at the factory and is
therefore ready for operation following commissioning
by your contractor:

tings on your room temperature controller or your
