4. Operating mode
To specify the operating modes for the heating circuit. After an interruption of
the mains voltage, the controller automatically returns to the last operating
mode selected.
Only in automatic mode does the controller use the set operating
times and the correspondingly set target flow temperatures!
Manual
In ‚Manual‘ mode, the individual relay outputs and the connected consumers can be checked for proper functioning and correct
assignment.
The operating mode ‚Manual‘ may only be used by specialists for brief function tests, e.g. during commissioning! Func-
tion in manual mode: The relays and thus the connected consumers are switched on and off by pressing a key, with no
regard to the current temperatures and set parameters. At the same time, the current measurement values of tem-
perature sensors are also shown in the display for the purposes of function control.
5. Settings
The basic settings for the control function of the heating circuit are applied.
Basic settings applied.
By no means does the controller replace the safety appliances on
site!
Operating mode
Heating=
Automatic/Normal mode using the set times.
Reference Value =
Fixed flow temperature regardless of the outdoor temperature. The desired flow temperature must be set in
Menu 4.3 .
14 days reference value program
= For the next 14 days, you can enter the menu 4. temperatures for the next 14 days. After 14
days, the reference temperature of the 14th day is used continuously until the operating mode is changed. Different temperature
values can be set in menu 4.4 for every individual day.
S/W Day
Summer / Winter changeover in daytime mode
If this value is exceeded at the outdoor sensor the controller automatically switches the heating circuit off = Summer mode. If the
outdoor temperature drops below this value, the heating circuit is switched on again = Winter mode.
In addition to the operating times in normal daytime operation, this setting is also valid for times with activated comfort.
S/W Night
Summer/Winter changeover in night-time mode
If this value is exceeded at outdoor sensor S1 during the nighttime mode times, the controller automatically switches the heating
circuit off = Summer mode. If the outdoor temperature drops below this value, the heating circuit is switched on again = Winter
mode.
