Chapter 6. SETTINGS DURING OPERATION
Time proportional cycle 1/2 setup
(1) In the operation display mode, keep the [para] key
pressed for 2 s or longer.
>>
The unit then enters the parameter setting mode.

(2) Press the [para] key several times.
>>
Display the parameter setting [Cy: Time
proportional cycle 1] or [Cy2: Time proportional
cycle 2].

(3) Press the [<], [
], or [
] key to change the set value
in [Cy].
Setting range: 5 to 120 s The output includes the relay output.
1 to 120 s The output does not include the relay
output.
>>
When no keys are pressed for 2 s or longer, the flashing of the numeric
value is stopped to set the currently displayed value.
(4) Press the [mode] key.
>>
The display is returned to the operation display.
Handling Precautions
• When the heat/cool control is not used, the time proportional cycle is set
using [Cy], and [Cy2] is not displayed. When using the heat/cool control,
the time proportional cycle of MV (manipulated variable) on the heat
side is set using [Cy] and the time proportional cycle of MV (manipulated
variable) on the cool side is set using [Cy2].
• When the proportional cycle setting of the relay output is less than 5 s,
the relay output is operated with time proportional cycle time of 5 s.
