If the amount of ventilation is too high, even in low mode, it is possible to have the
fans work intermittently or at a very low speed with setting 19(29)‑1.
INFORMATION
This function is NOT possible when there is a direct duct connection.
INFORMATION
For EKVDX combinations, this operation is disabled. Default setting is –1–01 and
should not be changed.
If the electrical heater is used, set setting 19(29)‑8 to 03 or 04 and setting 18(28)‑9
to 01. For more details, see the PCB heater manual.
WARNING
When combined with an EKVDX unit, do NOT install operating ignition sources
(example: open flames, an operating gas appliance or an operating electric heater) in
the duct work.
Terminals J2 and JC function as contact signal input to switch the heat reclaim
ventilation unit on or off.
INFORMATION
For EKVDX combinations, J2/JC function cannot be used. EKVDX is provided with
T1T2 external input to replace these functions.
The filter contamination check can ONLY be done in the same conditions as
19(29)‑0‑04 or 05. E.g., if the unit is operating in bypass mode, filter contamination
CANNOT be checked. In this case, a timer counts the hours. After a target value is
reached, the conditions are changed for a short time to be able to perform a filter
contamination check.
Setting 18(28)‑11‑02 resets the timer to 0.
Setting 18(28)‑11‑03 performs an immediate filter contamination check.
After finishing 18(28)‑11‑02 and 03, the setting automatically returns to
18(28)‑11‑01 and unit operation continues as before. Settings 18(28)‑11‑02 and 03
can ONLY be used when setting 19(29)‑0 is set to 01 or 02.
INFORMATION
This function is not possible in case of errors.
INFORMATION
For more detailed instructions on installation and operation, field settings,... refer to
the Installer and user reference guide of the EKVDX module.
