4.6.2 Hydraulic integration

A mixer must be installed when combining a calorifier with

underfloor heating. A minimum circulation water quantity

is not required.

4.6.2.1 Cascades

As a basic principle, the Hoval TopTronic should per-

form cascade control. This ensures an environmentally

and product-friendly method of operation. However, if an

external cascading strategy is planned and boiler perfor-

mance control is carried out, frequent cycles should be

avoided (at least 12 minutes burner running time).

Please observe the notes in the configuration

documents of the responsible Hoval sales

company with respect to the appropriate hy-

draulic switches!

Example:

UltraGas

(125 - 1150)

Gas boiler with

- water heating,

- Wall distributor with separate return

- 1 mixed heating circuit and water heating to high-

temperature return

- 1 mixed heating circuit to low-temperature return

Hydraulic schematic BCST050

Please close unused connections tightly

Important information:

• The example schematics merely show the

basic principle and do not contain all in-

formation required for installation. Instal-

lation must be carried out according to the

conditions on-site, dimensioning and local

regulations.

•

With underfloor heating, a flow temperature

limit thermostat must be installed.

• Shut-off devices to the safety equipment

(pressure expansion tank, safety valve,

etc.) must be secured against unintentional

closing!

• Install sacks to prevent single-pipe gravity

circulation!

• An automatic air vent (AAV) must be in-

stalled before the shut-off valve. This is not

supplied by Hoval.
