7.1.16Use of boiler sensor 2

Function Two single-stage heat generators

For sensing of the temperature in the second heat generator with double boilers or two single-stage heat generators (see "Heat Generator" menu, parameter 1 boiler type = 3)

Two measuring points in the combustion chamber

In order to reduce standby losses by increasing the burner runtimes. With automatic sensor switching between boiler sensor 1 and 2 after the burner switching cycle, the On signal for the burner will be determined by the upper sensor (BS1) and the Off signal by the lower sensor (BS2) based on the specified demand value and switching differential(s).

7.1.17External heat generator cut-off

Function If the assigned variable input is short circuited, there will be a permanent deactivation of the heat generator. It is cancelled again once the short-circuit is remedied.

ATTENTION

This function is meant exclusively for external override signals and not for safety switch off!

7.1.18Heat generator forced discharge

Function When the temperature in the heat generator exceeds the set maximum temperature limit, any excess energy is dissipated into circuits downstream. This function applies to all controllers on the bus system.

Set values OFF

No heat dissipation

Dissipation into hot-water tank

With provision tanks only

ATTENTION

Thermal mixing valve at water heater outlet obligatory because of scalding hazard.
