Solar circuit status ON/OFF; selection of the output
Maximum limit status ON/OFF (ON = cylinder limit reached at T.ref.
or T.lim.)
Status OFF if the maximum limit at the collector is active.
Status ON the collector temperature is higher than the minimum
threshold.
Status ON the reference temperature is lower than the maximum
threshold T.ref. max.
Status ON if the temperature at the limit sensor is lower than T.lim.
max.
Status ON if the collector temperature is higher than the reference
temperature by the amount of Diff. on or Diff. off.
Status OFF if the solar function is deactivated by the Solar priority
function.
Status ON when the time window for the stabilisation time applies
Counter which counts down the stabilisation time
Status OFF if the solar function is prevented from starting by blocking
during the blocking time of the Drainback function.
➢ The Maximum limit output variable switches to status ON if the maximum threshold of the
reference sensor T.ref. max. or the maximum threshold of the limit sensor (if connected)
T.lim. max. is reached.
➢ If no Solar priority function has been programmed, the Priority output variable is always set
to status ON.
➢ If there is no stabilisation time defined, the Time window output variable is always set to
status ON.
➢ If there is no Drainback function programmed, the Blocking (drainback f.) status is always
set to ON.
