Usage
These switches are used for setting
change with push switch SWP 1, 2 and 3.
Selects either the external water
temperature sensor or the built-in sensor
to be used to control water temperature.
Allows or disallows the analog signals
from a remote location.
Selects either the water temperature or
the capacity control ratio.
(Effective only when SW2-7 is set to ON.)
Enables or disables the automatic
restoration of operation after power failure
(in the same mode as the unit was in
before a power failure).
Selects analog input 4-20mA/
0-10V/1-5V/2-10V.
(Effective only when SW2-7 is set to ON
and SW3-4 is set to OFF.)
Switches the LED display of the control
board.
(Display is switched in the 3 second
intervals.)
