•2 core CY 0.5mm-1/5mm connection between controller and unit(s)

•When controlling more than one system, the units must be addressed using the Rotary

Dial S1 switch on the indoor PCB

•Both the HA/HB and Jack plug versions of the controllers look very similar except for

the fly lead that is connected to the bottom of the jack plugged version. Bear this in

mind when attempting to wire the controllers. The jack plugged version cannot be

connected using HA/HB even though the terminals are present
