CAUTION
Before carrying out wiring, turn off the power
to the controller and check that cables to be
connected are not alive with a tester or the like
because there is a possibility of electric shock.

Correspondence between parameter OT and heating-side/cooling-side output types
OT=6 OT=7 OT=8 OT=9 OT=10 OT=11 OT=12
* OT is a setup parameter.
You can change the settings of the parameter OT to change the
control output type.
See “2. Initial Settings,” for more information.
The control output types, “relay output” and “voltage pulse output” shown in the table above refer to those of time proportional control.
To change the type to a relay output for on-off control, select “Relay Terminals” and change the setpoint of the proportional band to “0.”

When switching target SP 1 to 8:
* If all of the contact inputs are set to OFF,
the controller uses the immediately
preceding target setpoint.
Note: External Contact Input
If the power is turned
on when the external
contact input is OFF,
the mode (SPN, R/L,
or A/M) existing before
the power is turned off
will be continued.
