INFORMATION
Refer to the installer and user reference guide of the user interface for more
information on how to change field settings.
NOTICE
In case an EKVDX indoor unit is installed, extreme setpoints can result in constant
thermostat ON behaviour. To prevent this, slightly increase (decrease) the respective
cooling (heating) setpoint.
INFORMATION
In case combined with EKVDX, on VAM, mode numbers 17, 18 and 19 CANNOT be
used. Use 27, 28, 29.
Field settings via user interface: for EKVDX, choose indoor unit 0. For VAM, choose
indoor unit 1.
In this chapter
19.1 To set the discharge temperature correction factor
The setpoint on the user interface of the EKVDX is related to the target discharge
temperature (Th4c), not to the target room temperature. Therefore, the measured
air temperature is not an accurate representation of the room temperature. Set a
correction factor 'c' to compensate for heat transfer in the duct length between
EKVDX and the room.
Formula:
for a given duct length between EKVDX and the room, c=length×0.10°C
Example:
For 10 m of duct: c=1°C.
19.2 To deactivate the R32 safety system
During a test run of the system and during maintenance, deactivate the R32 safety
system (active by default):
1
Set VAM setting 19(29)‑15-01
2
Set one of the two EKVDX settings: 15(25)‑13-3 (=OFF for 24 hours) OR
15(25)‑13-1 (=OFF)
After completion of test run or maintenance, activate the R32 safety system again:
3
Set VAM setting 19(29)‑15-02
4
Set EKVDX setting 15(25)‑13-02
