Air Temperature Adjustment
(applies to non-Danfoss temperature sensors only)
This parameter is a relative value and allows adjustment of the control
sensor temperature.
For instance, at a measured temperature of 7*C and "
tAd
" set to -2 K,
the input from the control sensor will be 5*C instead.

Inputs and outputs are configurable
There are two steps:
1.
Define the type of sensor attached to the input:
-
temperature
: light/digital.
2. Define the application for the sensor:
-
temperature
: control/condenser/evaporator.
-
light
: ECO/display/both.
- motion
-
digital
: door sensor.
Please contact your local Danfoss representative for information about
default settings.
NOTE: coded sensors will impact on the number of possible
configurations.
For instance: Danfoss supplies only 2-pole defrost sensors, so input "
S3
"
will most likely be used as a defrost/evaporator temperature sensor input.
