is the setpoint for the supply air temperature at which the unit
will switch to a lower speed in case of failure to attain the pre-
programmed temperature conditions.
Т4
is the temperature increase relative to
T1
for switching to the
pre-programmed speed.
Page 3/04. Setting up humidity/СО2 sensor feedback operation.
The
«Humidity sensor»
parameter enables changing the humidity
measurement location. To control the humidity level at the control
panel mounting location (if the panel is equipped with a humidity
sensor) select the
«th-Tune»
parameter.
If the unit is equipped with an external humidity/CO
2
sensor
and the
«exhaust air»
parameter is selected, the humidity/CO
2
measurements are taken at the sensor mounting location.
The fan speed (if the Auto fan mode is selected) will vary within the
parameters defined by setpoints from U1 and U3 to U2 and U4 so
that the humidity/CO
2
levels are maintained below the
«Humidity/
СО
2
set.»
threshold value.
