n case of condensation the

TC-3 is not react, not closing the
actuator
Mixed inlet water temperature
control is not works
The pump is not starting. (LED of
pump indication is not lighting).
The room temperature control is
not works( the actuators are not
opening or closing) or not measure
the real values (temperature and or
humidity).

Check the wire of dew point
sensor. Check the system is in
cooling mode.
Check first in fully open cases (10V
output) the mixing valve is
completly open as well. Check the
output voltage at 39-40 output
plugs of WTC-3. It must be 0-10V!
U
se a voltmeter! If the voltmeter
s
hows right value only in that case
when the mixing valve disconnec-
ted then need to be check the
connections of the mixing valve
Check the position of temperature
sensor, if It is installed to to the
right place. Check the measur
ed
water temperature with the
configuration program. If the vale is
not r
eal then check the wir
e.
In that case when no demand fr
om
the thermostats then the pump will
stop
Check the position of the program
selector
1. or 2. program:
standard room
thermostat,
3.program: (2. switch OFF):
DRT200 room
thermostat.
Check the right relationship of
room-thermostat-actuator
Check the room air temperature
with a thermometer and compare
the value with the temperature is
measured by DRT-200. If the diffe-
rence is more then 2-3C degrees
then the thermostat is not istalled
to the right place. Move it such a
place wher
e is higher ventillation.
Check the humidity sensor in the
DRT-200. Remove the white
pr
otection tape if its still ther
e
