Fan control
In addition to the fan functions during defrost the fans may also be stopped as a func-
tion of the compressor operation and if necessary a door function.
Fan stop on compressor cut out
Here you can select whether the fan must be stopped when the compressor is cut
out.
Delayed fan stop when compressor is cut out
If you have chosen to stop the fan when the compressor is cut out you can delay the fan
stop after the compressor has stopped. Here you set the time delay.
Fan stop temperature
The function stops the fans in an error situation, so that they will not provide power
to the appliance. If the defrost sensor registers a higher temperature than the one set
here, the fans will be stopped. There will be re-start at 2 K below the setting.
The function is not active during a defrost, start-up after a defrost, or if the AKV-ON
signal is interrupted.
With setting +50°C the function is interrupted.
Miscellaneous
Delay of output signal after start-up
After start-up or a power failure the controller's functions can be delayed so that over-
loading of the electricity supply network is avoided. Here you can set the time delay.
Digital input control
The controller has a digital input "DI" which can be used for one of the following func-
tions:
1) Door alarm. Connect a door switch and the controller will register when the DI
input is open. Subsequently, the controller will allow the function "door alarm".
2) Defrost. A contact function with returm spring is fitted. The controller will register
when the DI input is activated. The controller will then start a defrost cycle. If the
signal is to be received by several controllers it is important that ALL connections are
mounted the same way (DI to DI and GND to GND).
3) Night operation. Connect a switch. When the switch is cut in, there will be night
operation.
4) Main switch. Regulation is carried out when the input is short-circuited, and regula-
tion is stopped when the input is put in pos. OFF.
5) Coordinated defrost with cable connections. See wiring diagram. (If coordinated
defrost via data communication is used, setting 5 must not be used).
0) Setting should be 0 (OFF) when the DI input is not used
Address
If the controller is built into a network with data communication, it must have an
address, and the master gateway of the data communication must then know this
address.
These settings can only be made when a data communication module has been
mounted in the controller and the installation of the data communication cable has
been completed.
This installation is mentioned in a separate document "RC.8A.C"..
The address is set between 1 and 60
The address is sent to the gateway when the menu is set in pos. ON
Access code
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
OFF.
