SAUTER flexotron®400 - RDT410
Control modes
P100012103 16
Shutdown mode (Only if frost protection sensor has been configured)
Whenever the running mode switches to ”Off”, (normal shut-down or frost
protection is activated) the controller will go into ”Shutdown mode”. The
shutdown controller will control the output that is tied to the frost protection
function to maintain a constant 25°C at the frost protection sensor.
Outdoor compensation
In control mode 2, Supply air control with outdoor temperature compensation, the
supply air temperature setpoint can be displaced according to outdoor
temperature. The displacement starts from outdoor temperature S.P and reaches
the setpoint value + the compensation (CMP) at -20°C outdoor temperature. For
example: Normal setpoint = 20, S.P=10 and CMP = 5 will give the following
result:

Damper
It is possible to set a minimum limit value to the damper output signal. The
damper-output will then not go lower than the set value during normal operation.
On shut-down however the signal will go to zero.
In the output mode heating
– damper the damper will be fully open for
temperatures higher than the setpoint. On increasing heat demand the damper
will first close to the minimum value before the heating output starts to increase.
In the output mode cooling
– damper the damper will be fully open for
temperatures lower than the setpoint. On increasing cooling demand the damper
will first close to the minimum value before the cooling output starts to increase.
DI1, Fan indication
Unless the fan indication input is active (closed) indicating that the fan is running,
the controller will not start normal temperature control and an alarm will be
generated. An alarm will also be generated if the input is active (closed) when the
fan control output is off.
DI2, Extended running
Activation of this input will force the controller to running mode even if internal
scheduler is in Off-mode. The unit will run as long as the input is activated.
