Operation mode „Screed drying“
After „Screed drying“ mode selection the shown flow temperature sequence (see 9.1 ) gets started
immediately. If a lower flow temperature is desired, the flow temperature can be set up with the parameter
„Flow max. temperature“. If screed drying is interrupted caused by a fault (power breakdown, etc.), the
program (after fault correction) continues drying as shown in 9.1 automatically. An optional continuing day
can be selected with parameter „Screed days“. After screed drying completion the boiler will switch to
"heating time mode". The desired temperature can be set for each day (end of the program with setpoint=
0°C).
