Setting a time program
Example:
You want to set the same time program
for every day except Monday:
Select the period "Monday–Sunday"

Operating status for heating/cooling
The different operating statuses indicate
how central heating/cooling is imple-
mented via a heating/cooling circuit.
"Standard"
Central heating/cooling is implemented
with the standard room temperature
"Set room temp." (see page 25). The
flow temperature is automatically
matched to the outside temperature.
"Reduced"
Central heating/cooling is implemented
with the reduced room temperature "Set
red. room temp" (see page 25). The
flow temperature is automatically
matched to the outside temperature.
