Every demand can be carried out by means of a relay and/or a 0-10 V output. If both
the Relay and the 0-10 V option are activated, the demand uses both outputs in
parallel.
Example:
The potential-free relay R14 can be allocated to the shared relay Dem. 1, for exam-
ple. R14 will then become available for potential-free boiler demand in the heating
circuits and e. g. the DHW heating function.
Relay option
If the Relay option is activated, the submenu Relay appears, in which a relay can
be allocated to the demand.
The Boiler pr. min option is used for protecting a boiler against cooling. If the
temperature falls below the adjusted minimum temperature, the allocated relay will
be energised until the minimum temperature is exceeded by 5 K.
The Boiler pr. max option is used for protecting a boiler against overheating. If the
adjusted maximum temperature is exceeded, the allocated relay will be switched off
until the temperature falls by 5 K below the maximum temperature.
For this purpose, a boiler sensor is required.
0-10 V option
If the 0-10 V option is activated, the submenu 0-10 V appears, in which a 0-10 V
output can be allocated to the demand.
With this option, the controller can demand modulating heat generators equipped
with a 0-10 V interface.
The characteristic curve of the 0-10 V signal as a function of the set boiler tempera-
ture is defined by means of 2 set points according to the specifications of the boiler
manufacturer. At a temperature of TSet 1, the voltage signal of the heat generator
is Volt 1. At a temperature of TSet 2, the voltage signal of the heat generator is
Volt 2. The controller automatically calculates the characteristic curve resulting
from these values. If the permanent voltage option is activated, the parameter
Volt appears, by means of which a minimum voltage that is permanently applied to
the output can be defined.
