RTH Radiation value (radiation threshold) in W/m

above which rinsing is allowed.
Without a radiation sensor, the computer calculates the necessary temperature
increase for the long-term mean that launches rinsing from this value.

OPS Outputs used for rinsing. If a control output is allocated to the output, then the
analog stage 100 is additionally output at this control output.
(ex works = OPS1)
Setting range: combination of all outputs (such as OPS1, OPS23, OPS123…)
WTL Waiting time of low priority. This is the time in which the collector should reach
the temperature necessary for priority operation. If the waiting time is set to 0
the solar priority timer is deactivated. (ex works = 5 min)
Setting range: 0 to 99 minutes in increments of 1 min
PRT Pump run-time of low-priority. If the solar radiation to switch to priority is not
sufficient, the low priority is allowed again for this time.
If the pump run-time PRT is set to 0, the low priority is only allowed when
the maximum threshold for priority is reached (= absolute priority).
(ex works = 20 min)
Setting range: 0 to 99 minutes in increments of 1 min
After-running time ART
During the start phase, the pumps may repeatedly switch on and off for a long time,
especially with solar and heating systems with long hydraulic system lines. That is
detrimental especially for high efficiency pumps. This response can be reduced by using a
speed control or increasing the pump after-run time.
