Time program

Further information can be found in chapter
"Terminology" in the appendix.
Setting the time program for heating/cooling
Factory setting: One time phase from 00:00 to 24:00 h
for every day of the week with the operating status
"Standard".
Note
This setting is suitable for operation with underfloor
■
heating systems.
No time program can be set for a separate cooling
■
circuit.
Extended menu:

2. "Heating" or "Heating/cooling"
3. If necessary, / for the required heating/cooling cir-
cuit.
4. "Time program heating"
or
"Time proghtg/cooling"
5. Set the required time phases and operating status.
For the procedure for setting a time program, see
page 15.
Note
Rooms are neither heated nor cooled between the
■
time phases; only frost protection for the heat pump
is active ("Standby" operating status).
When making settings, please bear in mind that your
■
heating system requires some time to heat or cool
the rooms to the required temperature.
Heating system with heating water buffer cylinder
Further information can be found in chapter
"Terminology" in the appendix.
Setting the time program for the heating water buffer cylinder
Factory setting: One time phase from 00:00 to 24:00 h
for every day of the week with the operating status
"Standard".
The time phases for charging the heating water buf-
■
fer cylinder must cover all time phases for central
heating (for all heating circuits).
If you switch off charging the heating water buffer
■
cylinder by means of the time program (all time pha-
ses are deleted "- - : - -"), then there will be no cen-
tral heating.
We recommend that the heating water buffer cylinder
■
is heated continually.
Central heating/central cooling

Central heating takes place with the max. permissi-
ble flow temperature, irrespective of the outside tem-
perature.
Central cooling takes place with the min. flow tem-
perature, irrespective of the outside temperature.
