Heating/cooling control can be used on the E5@N-@2@@@, E5@N-@3@@@,
or E5@N-@Q@@@. Heating/cooling control operates when h-c (heating/cool-
ing) is selected for the "standard or heating/cooling" parameter.
The following functions are assigned to outputs in the initial status.
Parameter name
Control output 1 assignment
Control output 2 assignment
Alarm 1 assignment

Alarm 3 assignment (E5AN/EN
only)
Each output is automatically initialized as shown below when the control
mode is changed.

Note (1) No parameter assignment is displayed because there is no control output
2.
(2) Alarm 1 becomes the program END output unless the program pattern is
OFF.
(3) For the E5AN/EN, alarm 3 is assigned for control output (cooling) (alarm
output 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."
