In Cooling Mode, when the current temperature drops below the set value of OFF, the
relay circuit turns off, and turns on when the current temperature rises higher than
the set value of ON.
In Heating Mode, when the current temperature drops below the set value of ON, the
relay circuit turns on, and turns off when the current temperature rises higher than
the set value of OFF.
When the set value of ON is changed, the set value of OFF remains unchanged.
When the set value of OFF is changed, the set value of ON remains unchanged.
And two thermostat function is set the each point regardless the mutual set points.
An each function of the two-step, the floating and the limit can be carried out by
a combination of settings. In case of cooling mode, the temp. setting point of OFF
should be lower than that of ON. In case of heating mode, the temp. setting point of
OFF should be higher than that of ON.
Failure in observing the following could result in injuries

CAUTION
of operators, or damage and malfunction of the device.
●Be sure to check the each setting point and press [ENT] key to replace each setting
value and then return to normal operation.
●The minimum value difference between [ON] and [OFF] is 0.5℃. Do not make the [DIFF]
unnecessarily small. It may shorten the life span of the thermostat.

2.Change ON-OFF set value
Follow the instruction below when construction contractors setup the all values
(initializing for factory preset mode or shaking down, for example).
The following method can change ON-OFF set values of thermostat No.1 and No.2.
<Setting sequence>
Pressing none
The device is in normal operation, and the present temperature
is displayed.

Pressing the [ENT] key
Durning setting, from any mode, returning to normal operation is
possible after replacing values in memory. Existing values remain
valid until [ENT(Enter)] key is pressed, and normal operation
continues. Each set value remains protected even when the power
is disrupted. When the power is disrupted within one second after
returning to normal operation, the memory may be lost.
3．Example of changeing [OFF1] and [ON1] setting.
Following is the example of changing from ［OFF1] and ［ON1］ set values 0℃ and 2℃,
[OFF2] and [ON2] set values 1℃ and 3℃ to ［OFF1］and［ON1］set values 10℃ and 5℃,
［OFF2］ and ［ON2］ set values 1℃ and 3℃.
1.Press［SEL］key to confirm that［oF1］and［OFF1-value］are blinking alternately at
7SEG.. LED. The set value of [OFF1-value] means ［off1］value of 0℃.
2.Press［▲］key change from ［0.0］℃→［0.5］℃→・・・［9.5］℃→［10.0］℃.
3.Press［SEL］key to confirm that［on1］and［ON1-value］are blinking alternately at
7SEG.. LED. The set value of [ON1-value] means ［on1］value of 2℃.
4.Press［▼] key change from ［2.0］℃→［2.5］℃→・・・［4.5］℃→［5.0］℃.
5.Press［SEL］key to confirm that［oF2］and［OFF2-value］are blinking alternately at
7SEG.. LED. The set value of [OFF2-value] means ［off2］value of 1℃.
6.Press［SEL］key to confirm that［on2］and［ON2-value］are blinking alternately at
7SEG.. LED. The set value of [ON2-value] means ［on2］value of 3℃.
7.Press ［SEL］key shift through each setting for confirming.
8.Press［ENT］key to replase each setting value and then return to normal operation.
4.Keylock Function
Type ULE can lock keys to prevent wrong operations by pressing [UP] key and [ENT]
key simultaneously for five seconds. While the key locking function is actuated,
Setting Change mode cannot be selected by pressing [SEL] key. Only [Loc] is displayed
on and off. No other modes can be selected either by pressing other keys. Only [Loc]
is displayed on and off. The device will operate at preset values of [ON] and [OFF]
while Keylock function is actuated.
How to lock keys
Press [UP] key and [ENT] key simultaneously for five seconds.
How to cancel Keylock function
Press [UP] key and [ENT] key simultaneously for five seconds. [Loc] will be displayed on
and off. Keep pressing those keys. When the preset temperature is displayed, keylock
Function is canceled.
Failure in observing the following could result in injuries
!
CAUTION
of operators, or damage and malfunction of the device.
●When the device resets itself after an electric power failure, keylock Function
is canceled and should be actuated again.
●Key operations should be done while the present temperature is displayed.
[Setting the values for [OFF1]]
When [oFF1] and [OFF1-value] blinks alternately,
and the orange LED at the [OFF1} position,the
value for the [OFF1-value] setting can be changed.
Change [OFF1-value] by 0.5℃.
When the set value of OFF1 is changed,the set
value ON1 remains unchanged.
[Setting the value for[ON1]]
When [on1] and [ON1-value] blinks alternately,
and the orange LED at the [ON1] position, the
value for the [ON1-value] setting can be changed.
Change [ON1-value] by 0.5℃.
When the set value of ON1 is changed,the set
value OFF1 remains unchanged.
[Setting the values for [OFF2]]
When [oFF2] and [OFF2-value] blinks alternately,
and the orange LED at the [OFF2] position, the
value for the [OFF2-value] setting can be changed.
Change [OFF2-value] by 0.5℃.
When the set value of OFF2 is changed,the set
value ON2 remains unchanged.
[Setting the value for[ON2]]
When [on2] and [ON2-value] blinks alternately,
and the orange LED at the [ON2] position, the
value for the [ON2-value] setting can be changed.
Change [ON2-value] by 0.5℃.
When the set value of ON2 is changed,the set
value OFF2 remains unchanged.
[Returns to the current temperature mode]
