Dimensions with ± 1 % tolerance; transport weight indication with ± 4 % tolerance and operating weight indication with ± 2 %

tolerance

The indicated transport weight already includes the surcharges for normal sheet metal thickness tolerances, hence difference

downwards is possible.

Dimensioning insertion opening:

Positioning height: addition of at least 100 mm to dimension H1 resp. dimension H2

(mounted / not mounted fittings)

Positioning width: addition of at least 200 mm to dimension B1 resp. dimension B2

(mounted / not mounted fittings) 1)

Smallest transport dimensions once fittings, burner and terminal box have been removed (without cable ducting; with cable ducting

+ 75 mm on right). 2)

The boiler operating weight must be absorbed by the foundation in the area of the front and rear supports. 3)

Maximum weight incl. 100 % filled with water 4)

brief description of the system:

Control of the minimum return flow temperature via a separate control element (SR) in the boiler circuit and a boiler circuit pump as

primary circuit pump.

function description of the system:

The return flow temperature is controlled by actuating the three-way valve (SR). The return flow temperature sensor (FZ) measures the

boiler return flow temperature. If it falls below the setpoint, the volumetric flow of heating water to the boiler return is continuously

throttled by actuating the three-way valve (SR). When the return flow temperature rises above the setpoint, the three-way valve (SR)

reopens and the volumetric flow to the heating circuit increases.

Special planning notes:

A low-loss header or alternatively a flow header with bypass and non-return valve must be included when planning.

The boiler circuit pump must be switched to continuous operation or with an overrun of 60 minutes.

The accompanying temperature sensor built into the boiler supply flow connection socket must not be used for boiler temperature

control. For temperature control, use the temperature sensor supplied separately which must be built into the low-loss header.

The diagrams show only the control elements necessary for control. The boiler equipment required can be found in the

corresponding piping diagrams.

The system diagram provides a general guide to the possible configuration without obligation or claims as to its completeness. The

practical implementation is subject to currently applicable technical rules. Safety equipment must be installed in accordance with

local regulations.
