Executing Heating/Cooling Control Section 4-4
The following functions are assigned to outputs in the initial status.
Each output assignment is automatically initialized as shown below when the
control mode is changed.
Example: E5CN
Note (1) No parameter assignment is displayed because there is no control output
2.
(2) The output set for the Auxiliary Output 1 Assignment parameter becomes
the program END output unless the program pattern is OFF.
(3) For the E5AN/EN, the Auxiliary Output 3 Assignment parameter is set for
control output (cooling) (the Auxiliary Output 2 Assignment parameter is
set for alarm 2).
• The heating/cooling operation of the control outputs will switch when the
Direct/Reverse Operation parameter is set to “direct.”
• When DRS (Invert Direct/Reverse Operation) is assigned for an Event
Input Assignment (1 or 2), control will start with the contents set for the
Direct/Reverse Operation parameter inverted when the event input turns
ON, and with the contents left according to the setting when the event
input turns OFF. For details on event inputs and control combined with the
Direct/Reverse Operation parameter, refer to Control by Inverting Direct/
Reverse Operation on page 90.
• When heating/cooling control is selected, the Dead Band and Cooling
Coefficient parameters can be used.
