The presence detection takes place via a
presence key on the controller or via the
presence object (e.g. presence detector). A
press on the presence key activates the comfort
mode extension.
The presence detection takes place via an
external presence detector. The detector will be
coupled via the presence object. If presence is
detected, the comfort mode will be activated as
long as the presence detector detects
movement. The presence key is without
function.
During a presence detection the controller can
temporarily switch into the comfort extension –
depending on the active operating mode. The
parameter determines the time after which the
comfort mode extension is automatically
terminated.
Only if "Presence detection" = "presence key".
In parameterized mixed mode it is possible to
switch-over between heating and cooling.
Depending on the operating mode and the room
temperature, the switch-over takes place
automatically.
Switch-over takes place only via the "Heating /
cooling switch-over" object 35.
Only with the "heating and cooling" or "basic /
additional heating/cooling" mixed modes.
Determines when an operating mode switch-
over telegram will be transmitted automatically
to the bus via the "Heating / cooling switch-over"
object 35.
Only if "Switch-over between heating and
cooling" = "automatic"!
This parameter enables the "Disable controller"
object 40. There is no control until enabled
(actuating variables = 0).
When controller disable is active (dew-point
operation), the "
" LED lights up.
The valve is periodically opened (every 24
hours). Works against calcification and thus
prevents the valve from getting stuck.
