"t1A" Air Temperature Adjustment
(applies to non-Danfoss temperature sensors only)
Min. -20.0 K
This parameter is a relative value and allows adjustment of the control
Max. 20.0 K
Default 0.0 K sensor temperature.
For instance, at a measured temperature of 7*C and "tAd" set to -2 K,
"t2A"
the input from the control sensor will be 5*C instead.
"t3A"
"t4A"
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.
