Following functions are available. Select the function in menu
5.4.
Indication of buzzer alarm
When an alarm occurs, the circuit becomes closed between
the port 15 and 16. During normal operation, the port 15 and
17 is closed.
Cooling mode indication / Active cooling mode (4-pipe
cooling)
When the system turns into cooling mode, the circuit
becomes closed between the port 15 and 16. By using this
signal, it is possible to switch 3-way valve for 4-pipe cooling
or to assemble a display circuit indicating cooling mode. For
details of connecting the 3-way valve, refer to page 40 to 41
External pump control (GP10)
External pump (GP10) is used in case additional heater is
placed after 3-way valve that switches heating/hot water
(refer to page 27 for diagram).
Connect the circulation pump as shown below using the port
15 and 16 on X4 terminal.

Hot water circulation pump control (GP11)
In case the distance between hot water tap and hot water
storage tank is far, the hot water supply line temperature is
likely to drop and it may take time to supply hot water from
the tap. In that case, hot water circulation pump (GP11) is
applied to maintain hot water supply line temperature warm
(refer to page 22 for diagram).
For details of connecting the pump, refer to External pump
control (GP10).
NOTE
Mark up any junction boxes with warnings for external
voltage.

Connect the network connected cable (straight, Cat.5e UTP)
with RJ45-contact (male) to contact AA4-X9 on the display
unit (as illustrated). Use the cable grommet (UB2) in the
control module for cable routing.
