Summer mode
The automatic summer mode becomes active when the outdoor temperature
exceeds the adjusted summer temperature TSummer. This can be limited to a
daytime frame with the parameters Daytime on and Daytime off. Outside the
adjusted time frame, the lower temperature TNight is used in summer mode. In
summer mode, the heating circuit is switched off.
Remote access
The following types of remote access are possible:
Remote control: A device which allows manual adjustment of the heating curve,
thus influencing the set flow temperature.
Î In order to use a remote control, set the Type to RTA
Room control unit: A device incorporating a remote control as well as an addi-
tional operating mode switch.
Î In order to use a room control unit, set the Type to BAS.
The operating mode switch of the room control unit is used for adjusting the op-
erating mode of the controller. If a room control unit is used, the operating mode
can be adjusted by means of the room control unit only. The controller menu only
allows the activation of the operating mode Holiday.
Antifreeze function
The antifreeze function of the heating circuit can be used to temporarily activate
an inactive heating circuit during sudden temperature drop in order to protect it
against frost damage.
The temperature at the allocated antifreeze sensor Sen. Frost is monitored. If the
temperature falls below the adjusted antifreeze temperature TFrost, the heating
circuit will be activated until the antifreeze temperature is exceeded by 2 K, but at
least for 30 min.
Chimney sweeper function
The chimney sweeper function can be used for enabling quick access to measure-
ment conditions without having to navigate through the menu.
The chimney sweeper funtion is activated by default. The chimney sweeper mode
can be activated by pressing microbutton
♦
for 3 s.
In the chimney sweeper mode, the valve opens, the heating circuit pump is acti-
vated. If the chimney sweeper function is active, the Lightwheel
®
flashes yellow.
Additionally, Chimney sweeper and a countdown of 30 min are indicated on the
display.
When the countdown has elapsed, the chimney sweeper mode is automatically de-
activated. If, during the countdown, microbutton
♦
is again pressed for more than
3 s, the chimney sweeper mode will end.
