Floor drying
3.5
SERVice parameter SP60 (for second heating circuit: SP260, cf. 3.6)
is used to activate a fl oor drying process (functional heating or screed
curing). After the fl oor drying has been completed, the controller
operates regularly according to the switch position and the switching
commands. SERVice parameter SP60 (or SP260) then shows ‚9‘.
