4.6 Other settings
The function “CL/HT”
The thermostat can be connected to
a heating system or a cooling system.
The thermostat should be set on “HT”
for a heating system and on “CL” for a
cooling system. If necessary, adjust the
setting by pressing “mode” (15). Then
press “CL/HT” (13) until the desired
mode appears. Exit with “ok” (14).
The function “DLY”
The thermostat optionally can start your
heating system delayed (for a cooling
system, this is set by default). The ther-
mostat only starts your system after it
has been switched off for 5 minutes.
Presson“mode”(15)rsttoenable
the delay. Then press “DLY” (12) until
“DLY” appears on the display and exit

The function “1C/2C”
You can set the permissible temperature
uctuationor“span”.Thespandeter-
mines how much the ambient tempera-
ture may increase or decrease before
the thermostat responds. For example:
with a span of 1°C and a comfort tem-
perature set to 20°C, the temperature
maydecreasetoamaximumof19.5°C
(for a heating system) or increase to
20.5°C (for a cooling system) before the
thermostat responds. To set the span,
rstpress“mode”(15)andthenpress
“1C/2C” (11) until you see the desired
span in the display. Exit with “ok” (14).
