Thermo - On / Off control option
With DX-Interface series 1 it is possible to perform the thermo-On/thermo-Off control by three different ways.
• Standard thermo-On / thermo-Off control (Default setting).
Suitable for installations controlled by suction or discharge temperature.
The thermo-On / thermo-Off logic is decided based on the difference between the inlet temperature to the coil and the
set temperature on the remote controller or central controller.
•
By an external input.
The thermo-On / thermo-Off control can be driven externally by an input signal connected to the CN3 socket of the
PCB1 of the DX-Kit.
Setting note: DIP Switch 1 – Pin 6 of DX-Kit PCB2 (small PCB) must be switched on (PCB2-DSW1#6 switched ON).
Once the PCB DSW has been set, the input “i1” of CN3 is automatically set for thermo-On / thermo-Off control. The
setting of input “i2” is kept as set on the remote controller.
Please refer to Hitachi Indoor Units Service Manual for further information about the setting and connection of the
auxiliary inputs to CN3 socket.
•
By the duty signal.
For systems controlled by a duty signal it is possible to force the thermo-Off by the duty signal itself. When the duty
signal becomes the minimum of its range (0 V or 4 mA) the system will be switched to thermo-Off condition. To be
switched to thermo-On condition the duty must become higher than the 8% of its range.
