DIP Switch Settings - FTC4
Located on the FTC4 printed circuit board are 4 sets of small white switches known as DIP switches. The DIP
switch number is printed on the circuit board next to the relevant switches. The word ON is printed on the circuit
board and on the DIP switch block itself. To move the switch you will need to use a pin or the corner of a small flat
headed electrical screwdriver or similar.
DIP switch settings are listed below. Make sure to turn off both indoor unit and outdoor unit power supplies before
changing the switch settings.
For multiple outdoor units control with FTC4 (Slave), see separate manual supplied with the FTC4 (Slave) circuit board.
Notes
*1. OUT11 will be available. For safety reasons, this function is not available for certain errors. (In that case,
system operation must be stopped and only the water circulation pump keeps running.)
*2. SW4-2 is available only when SW4-1 is ON.
*3. If emergency mode is no longer required, return the switch to OFF position.
*4.
All pre-plumbed cylinders except for the 150 litre model come with DIP switches pre-set for 2 zone
function, in the case that only one zone is to be utilised you MUST turn OFF SW 2-6 and SW 2-7.
