Special operating programs and functions

"Screed drying"
This function is switched on by your contractor. Your
screed is dried in line with a set time program (tem-
perature/time profile) suitable for the relevant build-
ing materials. Your settings for central heating have
no effect on the duration of screed drying (max. 32
days). The system no longer provides DHW heating.
The
"Screed drying"
function can be altered or
switched off by your contractor.
■
"External hook-up"
The operating program set at the control unit was
changed over by an external device, e.g. an EM-EA1
extension (DIO electronics module). The operating
program cannot be changed via the control unit for
