Real Time Clock; Miscellaneous - Danfoss Optyma Plus User Manual

Integration Time Tn
If the Tn value is increased, the fan speed will change.
Amplification factor Kp max
The regulation uses this Kp, when the measured value is far from reference
Fan speed
The actual fan speed is read out here as a % of nominal speed.
Change in fan speed
A permitted change in fan speed can be entered for when the fan speed is to be low-
ered. The setting can be entered as a percentage value per second.
Jog speed
Set the fan's start-up speed here. After ten seconds the function jog function will stop
and the fan speed will then be controlled by the normal regulation.
Jog speed at low temperatures
Enter the desired jog speed for outside temperatures of -20°C and lower here.
(For outside temperatures between +10 and -20, the controller will calculate and
utilise a speed between the two jog settings.)
Fan control definition
0: Off
1: The fan is connected to terminal 5-6 and is speed-controlled by an internal phase
cut. The relay on terminal 15-16 connects at speed requirements of 95% or higher.
2: The fan is connected to an external speed control device. The speed control signal
is connected to terminals 28-29. The relay on terminal 15-16 will connect when
regulation is required. (During external control, the settings F14, F15 and F16 will
remain in force)
Minimum fan speed
Set the lowest permitted fan speed here. The fan will be stopped if the user enters a
lower speed.
Maximum fan speed
The fan's top speed can be limited here. The value can be entered by setting the
nominal speed of 100% to the desired percentage.
Manual fan speed control
An override of the fan speed control can be performed here. This function is only
relevant when the main switch is in service mode.
The LED on the controller's front will show whether Fan is in progress supplied either
through fan speed control output or fan relay.

Real time clock

When using data communication the clock is automatically adjusted by the system
unit. If the controller is without data communication, the clock will have a power
reserve of four hours.
Switch to day operation
Enter the time at which the control reference becomes the entered set point.
Change to night operation
Enter the time at which the control reference is raised with r13.

Clock: Minute setting
Clock: Date setting
Clock: Month setting
Clock: Year setting

Miscellaneous

If the controller is built into a network with data communication, it must have an ad-
dress, and the system unit of the data communication must then know this address.
The address is set between 0 and 240, depending on the system unit and the selected
data communication.
The function is not used when the data communication is MODBUS. It is retrieved
here via the system's scan function.
Access code 1 (Access to all settings)
If the settings in the controller are to be protected with an access code you can set a
numerical value between 0 and 100. If not, you can cancel the function with setting 0.
(99 will always give you access).
