1.  Descripton FD-PAC / Warranty exclusion 

Control kit for connecting an optional heat exchanger on a FDC outdoor unit for cooling and heating 
(refrigerant R410A).The control kit is fully wired and contain the electronics with microprocessor for 
communication with the FDC outdoor unit. The selfdiagnose system provides a fast recognition of 
problems and provides alpha numeric codes on the remote controller. Via DIP switches the PCB 
needs to be configured in relation with the optional equipment. The temperature sensors are included 
in this delivery. 
 
The equipment will be controlled via a remote controller with actual time and timer functions, 
ventilation selections and operation/warning connections (CNT contact). 
 
The control kit can be switched on/off via an external 230V AC signal. Via optional PCB’s the control 
kit can be combined in a central controller.  
 

Caution: The manufacturer is obliged to give warranty on the delivered components and 
therefor not responsible for the operation and control of the equipment which is connected to 
the control kit FD-PAC!  
Furthermore there is no warranty or a possibility to claim ensuing damage which is the result 
of wrong calculation, selection of heat exchangers, positioning of sensors, planning and 
installation mistakes. 
 
When using the control kit in combination with cold water equipment via plate heat exchangers 
there must be a minimum of 15% glycol in the system. For other constructions or applications 
a minimum of 15% glycol is recommended.
