There are 4 temperature levels available. In manual mode only one
temperature level is active (icon in the frame indicates which mode is
currently choosen). For each temperature levels you can set a dierent
temperature.
The NSB (Night SetBack) function can automatically change temperatures
on VS35 daily thermostats via VS30 programmable thermostat connected to
a wiring centre (or another external clock). NSB function switches between
comfortable temperature and economic temperature .
The VS35 thermostat allows you to adjust the displayed temperature ± 3.0°C.
You can do it according to the following steps:
To activate the automatic mode, select the icon. On display together with
the icon, the controller indicates active temperature mode: or .
- Comfort mode
- Standard mode
- Economic mode
- Frost protection mode. Usually used in a longer period of absence
or during the holidays (available only in heating mode).
Press any button to highlight the screen, then follow the steps below:
Note: You can also set the Oset temperature value using the service
parameter d02.
Note: For the NSB function to work, it is necessary to connect the wirings
properly. Connection diagrams can be found on the previous page.
