"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"
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.
"S1C" S1 Config/S1C
S2 Config/S2C
Default Stn
S3 Config/S3C
Available options are:
"S2C"
"Stn": for a standard temperature sensor NTC 5 K @ 25°C and TPE precision.
Default Stn
"Htn": for a high temperature sensor NTC 100 K @ 25°C.
"Ldr": for a light sensor (values given in Luminens).
"S3C"
"dig": for a digital sensor with simple ON/OFF indication
Default Stn (motion, magnet, switch, buttom).
"S1A" S1 Application/S1A
S2 Application/S2A
Default SCo
S3 Application/S3A
Available options are:
"nC": not connected.
"S2A"
"SCo": temperature control.
"EuA": evaporator temperature.
Default nC
"Con": condenser temperature (Condenser cleaning).
"S3A"
"AuS": only for showing temperature on display.
"Ldr": light sensor, Luminens.
Default nC
"ECo": external input to control ECO mode.
"doC": door contact, contact closed when door closed.
"doo": door contact, contact open when door closed.
"Pir": motion sensor (only "S3").
"diC" DI Config
This is the digital input used for a digital sensor or bus communications.
Default non
"non": not used.
"doC": door contact, contact closed when door closed.
"doo": door contact, contact open when door closed.
"ECo": external input to control ECO mode.
"Pir": motion sensor. Passive infrared.
"o1C" D01 Config
Condenser relay will follow the compressor ON/OFF, it will be turned On whenever compressor is ON and turned off when com-
Default Con
pressor is OFF.
"Con ": condenser fan control
"PiC": pilot Relay (no zero cross) – if using pilot relay to control a
condenser, this option must be used instead of "Con".
