Heat exchange function
The heat exchange function can be used for transferring heat from a heat source
to a heat sink.
The relay (system-dependent) is energised when all switch-on conditions are ful-
lled:
• the temperature difference between the sensors heat source and heat sink has
exceeded the switch-on temperature difference.
• the temperature at the heat source sensor has exceeded the minimum temperature
• the temperature at the heat sink sensor has fallen below the maximum temperature
When the Set temperature difference is exceeded, pump speed control starts. For
every increase or decrease by the rise value, the pump speed will be adjusted by 10 %.

Afterheating / Thermostat function
The thermostat function works independently from the solar operation and can e.
g. be used for using surplus energy or for afterheating.
• AH O < AH F thermostat function for afterheating
• AH O > AH F thermostat function for using surplus energy
In order to block the thermostat function for a certain period, there are 3 time
frames t1 … t3. The switch-on and switch-off times can be adjusted in steps of 15
min. If the switch-on and the switch-off times are identical, the time frame is inactive.
If the thermostat function is supposed to run from 06:00 a.m. and 09:00 a.m. only,
adjust t1 O to 06:00 a.m. and t1 F to 09:00 a.m.
The rst time frame is factory set from 06:00 to 22:00.
If all time frames are set to 00:00, the thermostat function is solely temperature
dependent.
