until 23:00. The economic tempera-
ture is maintained between 23:00 and
06:00. Program 0 is the frost protec-
tion program. Here, the entire day and
night the frost protection temperature is
maintained.
4.4 Modifying programs
• To modify a program, follow the steps
below:
• Press “prog” (9)
• Then repeatedly press “prog” (9)
until you are on the day of the week
for which you want to choose the
program (modification is only possible
of program 10 thru 19).
• Run through the program profile
(21) of that day of the week (starting
at 00: 00 hours) in order to modify
the program. If you want comfort
temperature on a block of time,
press (3). If you want economic
temperature on a block of time, press
(4). After the choice between
comfort and economic temperature
you automatically continue to the next
block of time. Once you are satisfied
with the program profile of the day,
exit with “ok” (14).
4.5 Temporarily deviating from a
program
You can deviate from a program by
selecting the opposite mode. For exam-
ple: The program has set the thermo-
stat to economic temperature. But you
temporarily want a higher temperature.
Press (3). The thermostat temporar-
ily switches to comfort temperature. The
thermostat returns to the programmed
setting by pressing “ok” (14), or when a
new hour begins.
To deviate from a program for more than
an hour, press and hold (3) for 2 sec-
onds. Press again to change the time
of the deviation. Up to 24 hours may be
deviated from the program. The thermo-
stat then automatically switches back in
the programmed temperature. To devi-
ate from the comfort temperature follow
the same actions, but instead press .
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) first to enable
the delay. Then press “DLY” (12) until
“DLY” appears on the display and exit
with “ok” (14). To turn off the delay, fol-
low the same procedure but make
sure that “DLY” is not shown in the dis-
play.
The function “1C/2C”
You can set the permissible temperature
fluctuation 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,
first press “mode” (15) and then press
“1C/2C” (11) until you see the desired
span in the display. Exit with “ok” (14).
