Functions
Functions enable the pre-programmed solar systems (see chapter 4) to be individually adapted to your
system. Thus the system regulator can implement special solutions and "develop" with the system’s
add-ons.
Pre-programmed solar systems and functions can access and evaluate the same sensors. Functions
can even access the outputs already “occupied” by the system control. Thus pre-programmed output
controls can be supplemented or improved by functions. If several functions access the same output,
a logical link of the switching conditions is required. These 'Links' are explained in more detail in
chapter 6.
Examples of common adjustments or add-ons, which arise from the functions are explained in more
detail in chapter 7 ("System examples").

Thermostats
The system regulator has 5 adjustable thermostats, with which individual outputs can be controlled
depending on the temperature.
To activate a thermostat, select the desired thermostat in the menu 'Settings -> 'Service' -> 'Functions'
-> 'thermostats' and press the OK button for 2 seconds (
-->
:
).
The most important Settings of each activated thermostat can be customized. Most importantly, in
addition to selecting the required temperature input and output to be controlled, the switching
thresholds can be set. Both the switch-on and switch-off temperature are factory preset to 20°C.
The thermostat cannot function with these values because at least one hysteresis (differential
temperature between switch-on and switch-off value) of 1°C must be present.
A switch-on temperature higher or
lower than the switch-off temperature
can be selected. Thus, both cooling
and heating functions can be
implemented.
The sensor inputs "E1 (regulator)" to "E7 (regulator)" are available on the regulator or the inputs "E1 (IOBox)" to "E4 (IOBox)"
are available on each of the four possible add-on devices (for additional IO boxes see chapter 9.1).
The sensor outputs "R1 (regulator)" to "R4 (regulator)" are available on the regulator or the outputs "R1 (IOBox)" to "R3
(IOBox)" are available on each of the four possible add-on devices.
