Switch-on diff.
–
You can use this function to define a differential value for
starting the differential temperature control, such as solar
heating support.
If the difference between differential temperature sensor 1
and differential temperature sensor 2 exceeds the specified
switch-on differential and the minimum temperature at differ-
ential temperature sensor 1, the system control then controls
the differential temperature output. The differential temperat-
ure control starts.

Switch-off diff.
–
You can use this function to define a differential value
for stopping the differential temperature control, such as
solar heating support.
If the difference between differential temperature sensor 1
and differential temperature sensor 2 falls below the spe-
cified switch-off differential or exceeds the maximum temper-
ature at differential temperature sensor 2, the system control
then controls the differential temperature output. The differ-
ential temperature control stops.

You can use this function to set a maximum value for the
air quality.
If the air quality exceeds the maximum value specified, the
system control activates the
recoVAIR.../4
ventilation unit
accordingly. You will find a detailed functional description in
the
recoVAIR.../4
manual.

tem control is.
4: The radio link is within the acceptable range. If the recep-
tion strength is < 4, the radio link is not stable.

door temperature sensor is.
4: The radio link is within the acceptable range. If the recep-
tion strength is < 4, the radio link is not stable.
10: The radio link is highly stable.
