Field Setting
3.7
Detailed Explanation of Setting Modes
3.7.1 Cool/Heat Mode Switching (Heat Pump Connection)
There are the following 5 cool/heat switching modes.
(1) Set cool/heat separately for each condensing unit system by indoor unit remote controller.
(2) Set cool/heat separately for each condensing unit system by cool/heat selector.
(3) Set cool/heat for more than single condensing unit system simultaneously in accordance with unified master
condensing unit by indoor unit remote controller.
(4) Set cool/heat for more than single condensing unit system simultaneously in accordance with unified master
condensing unit by cool/heat switching remote controller.
(5) Set cool/heat at all condensing unit systems simultaneously for each condensing unit external control adaptor by using
the central remote controller.
(1) Set Cool / Heat Separately for Each Condensing Unit System by Indoor Unit Remote Controller
It does not matter whether or not there is condensing - condensing unit wiring.
Set condensing unit PCB DS1-1 to IN (factory setting).
Set cool/heat switching to IND (individual) for “Setting mode 1” (factory setting).
3. Data such as addresses and number of units is expressed as binary numbers.
The No. 1 cool/heat unified address is expressed as a binary number consisting of the lower 6
digits. (0 - 63)
(Example 1)
In (Example 1) the address is 010110 (binary number), which
translates to 16 + 4 + 2 = 22 (base 10 number). In other words, the
address is 22.
4. The number of connected Branch Selector units for No.9 and 10 / the number of terminal
blocks for No. 12 and 13 is expressed as an 8-digit binary number, which is the combination of
4 upper, and 4 lower digits respectively. (0 - 128)
(Example 2)
In (Example 2) the address for No. 12 is 0101, the address for No. 13
is 0110, and the combination of the 2 is 01010110 (binary number),
which translates to 64 + 16 + 4 + 2 = 86 (base 10 number). In other
words, the number of terminal block is 86.
