Check connection of electric
power at plug 1 and 2 with
measurement unit
Check the connection between
the 46-47 plug of WTC-3 and
3-4plug of DRT-200 (polarity,
demage, shortcut).
Reversed polarity NOT allowed!
C
heck the program setting on
program selector at back side of
WTC-3
Set the proper address for every
DRT-200 (1..7). check the status of
every connected DRT-200 via
configuration program
According to the factory default the
master DRT-200 can change only
the H/C mode.
Check the settings of H/C change
over with configuration program
Check the settings of C/E change
over with configuration program
Check the settings of ON/OFF
change over with configuration
program
This is not a fault. WTC-3 is in
change over mode. Wait until the
delay is in progress (default: 10
minutes
Disconnect the dew point sensor.
The condensation sign must to
finish at WTC-3. Check the wire
for demage, brake or shortcut.
Check the connection. This could
happen only in case if the dew
