Furthermore, the following output can be obtained.
(3) Operation output (voltage free contact)
The signal can be obtained as a voltage free contact external
signal during operation.

(4) Alarm output (voltage free contact)
Signals for high temperature alarm,
low temperature alarm and system
alarms can be obtained as an
external signal of the voltage free
contacts.
NOTE: One signal for all outputs.

(5) Hot water outlet temperature (analog signal)
The outlet temperature of water can be obtained from the control panel as
a 4 mA to 20 mA external signal.
When obtaining the hot water outlet temperature via analog signal, the
output range should be: 4 mA

(6) Emergency stop input (voltage free contact)
(standard models only):
When there is a requirement for
components other than the unit, such
as master control panels or
temperature switches, to force the
unit to do an emergency stop from
the control circuit, these terminals can
be used to conduct the emergency
stop.
(Emergency stop refers to a loop that
forcefully stops the power supply to
the sequencer which contains the
unit’s control program.)
The unit cannot restart while the
emergency stop input is consistently
supplied.
Furthermore, since the loop forces
the power supply to the sequencer and touch panel to be shut down, the
operation history will not remain in the alarm log.
