IMPORTANT

All distribution manifold inline installations can not be free

standing and must be securely fastened to the floor and

the wall.

Wall mount or wall and floor installations must be capable

of supporting the weight of the boilers, distribution

manifold(s) and insulation.

Cascade System Guide

Wall Mounted Multiple Boilers (without manifold)

Using standard Viessmann components, a maximum of 4 same size boilers can be connected in a cascade system using

a LL distribution manifold or field piped system (as shown below).

For systems requiring more than 4 boilers a custom Viessmann control is required.

For systems that do not use the LLDM (field piped

systems) the contractor must size the pump according to

the pressure drop of the piping and the pressure drop of

the boiler heat exchanger.

For a list of recommended heating circuit/boiler pumps

refer to page 11.

A low loss header must be installed between the primary

boiler circuit and secondary system circuit. The LLH must

be sized to accommodate the highest flow rate.

All supply and return pipes are field supplied.

Control options for cascade system not using LLDM.

Vitocontrol-S WB2B cascade control.

For systems up to 4 boilers of the same size, using KMK

bus communication between the Vitotronic HC1 boiler

control and the Vitocontrol-S WB2B cascade control.

BMS or third party cascading controller

For systems up to 4 boilers of the same size, using

0-10VDC temperature signal between the Vitotronic 200

HO1 and the third party controller.

Control for Heating System Loop

Additional Mixing Valves

Vitocontrol-S, is capable of controlling (1) high

temperature circuit and (2) low temperature circuits with

mixing valves.

Refer to the price book 1 and 2 for available 3 and 4 way

mixing valve sizes and corresponding part numbers.

BMS tie-ins to the Vitocontrol-S will require additional

integration equipment, the following integration equipment

is available from Viessmann;

0-10VDC Extension input module

Versatronik 505 BACIP Gateway

Versatronik 505 LONIP Gateway

External mixing valve controllers are required when

controlling 3 or more mixing valve circuits, use one

Vitotronic 200 HK1M (PN 7134627) in conjunction with

the Vitocontrol-S for each additional mixing valve circuit

in the system.

Additional equipment required when installing a Vitotronic

200 HK1M are as follows;

- (1) LON Connection cable 23 ft. (7 m) (7143495)

- (1) LON Terminal end resistors 92 pieces ( 7143497)

- (1) LON Communication modules for HK1M (7172173)

- (1) LON Communication modules for WB2B (7179113)

Venting Systems

Each boiler must be vented separately using one of the

following certified venting systems:

- Coaxial PP(s)

- Stainless steel

- CPVC Vent

- Flexible PP(s)

- PP(s) rigid venting

Refer to the Venting Installation Instructions

for more detail.

Preparing the single boiler connections to the pump power module and coding addresses that needs to be changed.

Coding changes for the Vitotronic 200, HO1 boiler:

- No coding changes are required, boiler control is capable

of automatic recognition, if the BMS system fails to

recognize the Vitotronic 100 HO1, please refer to the

Vitodens 200 WB2B Start-up/Service Manual.
