Detailed descriptions of the parameters are provided
below.
5.8.1.1 Switch off boiler at
Explanation of [Switch off boiler at]
This parameter determines at what temperature of the
external heat source the ETA boiler switches to
[Locked] mode.
If the temperature of the external heat source lies
below this temperature [Switch off boiler at], the ETA
boiler always supplies the heat. If this temperature is
exceeded, the ETA boiler switches to [Locked] mode.
The parameter can be found under:
5.8.1.2 Enable diverter valve
Explanation of [Enable diverter valve]
Optional: Only with diverter valve
This parameter is used to set the minimum
temperature for the switchover between the ETA boiler
and the external heat source.
If the temperature of the external heat source is below
this minimum temperature, the diverter valve switches
to the ETA boiler, which then supplies the heat. If this
temperature is exceeded, the valve switches to the
external heat source, which supplies the heat.
The parameter can be found under:
5.8.1.3 Enable temperature
Explanation of [Enable temperature]
Optional: only with charging pump
This parameter sets the minimum temperature of the
external heat source, for starting the charging pump of
the external heat source.
The parameter can be found under:
5.8.1.4 Thermostat diff.
Explanation of [Thermostat diff.]
Optional: only with charging pump
This parameter is used to set the minimum difference
between the temperature of the external heat source
[Ext. heat] and the tank that needs charging [Tank tem-
perature], to start the charging pump of the external
heat source.
