4.Switch Settings
T u rn the power on after all the switches have been set.
NOTE
Settings made while the power is on are invalid.
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.
Destination SW3-3 setting
OFF

Overseas ON
(2) Group number settings (SW1 and SW2-1 to SW2-3)
Set these when using the central controller. (Set to the
than one unit to the same number.
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
central controller.)
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 source is needed when using the
schedule timer independently.
Power source specs: DC 16V, +10%, -15%, 200mA.
Recommended power source: 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.
SW2-4 setting

(4) Contact input function settings (SW3-1 to SW3-2)

NOTE1: Since central 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 central controller while the air
conditioner is stopped with an open contact, the contact will be
open and the unit will be running.
NOTE2: Operating mode and fan direction and speed settings can be changed.

What Happens
"Automatic" operation is not available from the central controller.
When using "automatic" operation using the wireless remote
controller, the central controller displays automatic cooling
(heating) and 77 °
F (25°C). Even if the temperature is changed, it
will return to 77°F (25°C) after a while.

The Operating / error signals can be read from the contact output (S5).
Output specs
M1: T u rn MR 1 ON when the air conditioner is running.
M2: T u rn MR 2 when a communication error has occurred between the KRP928B2S and
the air conditioner, or MR 1 is ON and the unit has stopped after an error.
MR 2 is not turned ON during a warning.
