SW2
setting
Open the Kit’s case and set the switches on the circuit board.
(1) For Overseas / Japanese unit setting (SW3-3)
Room air conditioners, different methods are used for setting the temperature in automatic mode, so this switch
needs to be set.
Turn the power on after all the switches have been set.
Settings made while the power is on are invalid.
“Automatic” operation is not available from the centralized control equipment.
When using “automatic” operation using the wireless remote controller, the centralized
control equipment displays automatic cooling (heating) and 25
°
C. Even if the temperature
is changed, it will return to 25
°
C after a while.
However, these settings do not need to be made when using the schedule timer independently.
(The settings are needed when used in conjunction with another DCS Series centralized control equipment.)
In this case, the schedule timer performs an auto address after the power is turned on, so new group numbers are
automatically set. Settings made using the switches will be overwritten.
NOTE also that a separate timer power supply is needed when using the schedule timer independently.
Power supply specs: DC 16V, +10%, -15%, 200mA.
Recommended power supply: Omron S82J-01015A. (Should be used with the output voltage adjusted to the center, DC 16V.)
(3) Settings when recovering from a power outage (SW2-4)
This selects whether to restart operation when the power comes back on after a power outage occurred
during operation. This setting is given priority in cases where the indoor unit has an auto start ON / OFF
jumper. Note also that regardless of whether switch SW2-4 is on or off, the operating mode, set temperature,
fan direction and speed settings, and remote control prohibition status are stored.
The operating status of the air conditioner is reversed
by an instantaneous input of 100 msec or more.
Contact - Open to close: air condition runs.
Close to open: air conditioner is stopped (NOTE 1.).
Contact - Open to close: air condition stops (forced
stop). Close to open: no change in operating status.
Forced stop or remote
controller permission input
ON / OFF control is rejected (operate /
stop / timer prohibition) (NOTE 2.).
During a forced stop, all remote
controller actions are prohibited.
Note:
1. Since centralized control equipment and HA JEM-A-compatible equipment both use last command priority, the contact status
and operating status of the air conditioner might not match sometimes.
Example: If the unit is run from the centralized control equipment while the air conditioner is stopped with an open contact, the
contact will be open and the unit will be running.
2. Operating mode and fan direction and speed settings can be changed.
(4) Contact input function settings (SW3-1 to SW3-2)
When using contact input (S1), choose one of the following functions.
Run / stop Input
Contact specs
No-voltage minute electric current contact
(Minimum applicable load DC 12V, 1mA or lower)
Total wire length max: 100m
