• Heating
If the temperature measured drops below the target value, then output
A3 is activated until the temperature measured reaches the target value
+ hysteresis.

• Temperature difference
For independent temperature difference controllers, minimum (e.g. solid
fuel boiler) and maximum temperature limits possible.
If the difference between both measurement points exceeds the hystere-
sis set, then A3 is activated.
In addition, one may also define a maximum temperature for the energy
consumer and a minimum temperature for the energy source.

1. TUBE COLLECTOR OR START FUNCTION
If the function is active, then the solar circuit pump is started using a
time frame, independently of the actual collector temperature. In this
way, the medium is transported to the measuring point for the collector
temperature.
