Maximum temperature: °C Set the maximum cylinder charging temperature for the cylinder
protection.
If the temperature at the bottom cylinder temperature sensor is
higher than the set maximum cylinder charging temperature, the
solar charging is interrupted.
The solar charging is only enabled again once the temperature
at the bottom cylinder temperature sensor has fallen by between
1.5 K and 9 K, depending on the maximum temperature. The set
maximum temperature must not exceed the maximum permissible
cylinder temperature of the cylinder.
Factory setting: 75 °C
Solar cylinder, bottom: °C Display of the current temperature in the lower section of the solar
cylinder
2nd diff. temp. control
Switch-on differential: K Setting the differential value for starting the differential temperature
control, such as solar heating support.
If the temperature difference between differential temperature
sensor 1 and differential temperature sensor 2 is greater than the
set switch-on differential and the set minimum temperature at
differential temperature sensor 1, the differential temperature
control is started.
Factory setting: 12 K
Switch-off differential: K Setting the differential value for stopping the temperature differ-
ence control, such as solar heating support.
If the temperature difference between differential temperature
sensor 1 and differential temperature sensor 2 is lower than the
set switch-off differential and the set maximum temperature at
differential temperature sensor 2, the differential temperature
control is stopped.
Factory setting: 5 K
Minimum temperature: °C Setting the minimum temperature for starting the differential tem-
perature control.
Factory setting: 0 °C
Maximum temperature: °C Setting the maximum temperature for stopping the differential tem-
perature control.
Factory setting: 99 °C
Diff. temp. sensor 1: Display of the current temperature at differential temperature
sensor 1
Diff. temp. sensor 2: Display of the current temperature at differential temperature
sensor 2
Diff. temp. sens. output: Display of the current control command at the connected actuator
Radio link
Sys. control reception strength: Read the reception strength between the radio receiver unit and
system control.
– 4: The radio link is within the acceptable range. If the reception
strength is < 4, the radio link is not stable.
– 10: The radio link is highly stable.
Remote control 1
Remote control 2
OT sensor reception strength: Read the reception strength between the radio receiver unit and
outdoor temperature sensor.
– 4: The radio link is within the acceptable range. If the reception
strength is < 4, the radio link is not stable.
– 10: The radio link is highly stable.
Screed drying profile Setting target flow temperature per day in accordance with the
construction regulations
