4-4 Executing Heating/Cooling Control
4-4-1 Heating/Cooling Control
Heating/cooling control operates when h-c (heating/cooling) is selected for
the “standard or heating/cooling” parameter.
The following functions are assigned to outputs in the initial status.
Each output is automatically initialized as shown below when the control
mode is changed.
Example: E5CZ
Note For the E5AZ/EZ, alarm 3 is assigned for control output (cooling) (alarm out-
put 2 is assigned for alarm 2).
• The heating/cooling operation of the control outputs will switch when the
“direct/reverse operation” parameter is set to “direct.”
• When heating/cooling control is selected, the “dead band” and “cooling
coefficient” parameters can be used.
In this manual, assigned control outputs and alarm outputs are indicated as
follows: “Control output 1 must be assigned” or “Alarm 1 must be assigned.”
7. Press the U and D keys to set 1.
8. To return to the operation level, press the O key for one second.
