Changing Operation of the CnT connector, 635566’s, On/Off Control.
The On/Off operation characteristics can be changed by either setting Jumper1 and Jumper3 (or SW7-1 and SW7-3 if fitted)
on the indoor PCB or via the “IU Function settings” menu on the wired remote control RC-E5, RC-EX1A or RC-EX3. To make
the setting via the wired remote control please see the remote control installation instructions.
To configure the ON/Off operation via the indoor unit control PCB, (FD models only) see below.
Normal operation, [Default setting], J1 & J3 are intact. (SW7-1 and SW7-3 both on
When CnT contact 1 to 6 is closed, operation starts, and when it is open operation stops.
Re-start from the remote controller is allowed.
Pulse operation, when J1 is cut & J3 is intact, (SW7-1 off and SW7-3 on).
Each time CnT contact 1 to 6 is pulsed open/closed/open, the operation changes over. (on to off/off to on).
Re-start from the remote controller is allowed.
Operation prohibited control (A), when J1 is intact & J3 is cut (SW7-1 on and SW7-3 off).
When CnT contact 1 to 6 is open, the unit will stop and re-start from the remote controller is blocked.
When CnT contact 1 to 6 is closed, the unit remains stopped but re-start from remote controller is allowed.
Operation prohibited control (B), J1 & J3 are cut, (SW7-1 and SW7-3 both off).
When CnT contact 1 to 6 is open, the unit will stop and re-start from the remote controller is blocked.
When CnT contact 1 to 6 is closed, the unit will auto restart.
To configure the ON/Off operation via the SC-BIKN-E interface PCB, (SR models only) see below.
Normal operation, [Default setting], SW2-1 and SW2-3 both on.
When CnT contact 1 to 6 is closed, operation starts, and when it is open operation stops.
Re-start from the remote controller is allowed.
Pulse operation, when SW2-1 off and SW2-3 on.
Each time CnT contact 1 to 6 is pulsed open/closed/open, the operation changes over. (on to off/off to on).
Re-start from the remote controller is allowed.
Operation prohibited control (A), when SW2-1 on and SW2-3 off.
When CnT contact 1 to 6 is open, the unit will stop and re-start from the remote controller is blocked.
When CnT contact 1 to 6 is closed, the unit remains stopped but re-start from remote controller is allowed.
Operation prohibited control (B), SW2-1 and SW2-3 both off.
When CnT contact 1 to 6 is open, the unit will stop and re-start from the remote controller is blocked.
When CnT contact 1 to 6 is closed, the unit will auto restart.
