Operation Instruction
•
In normal working status, the screen display
RT
(real time
temperature value).
•
①
Cooling mode:
HC set to C. use cooler as load. When
RT
≥
ST
(temperature set value) +
D
(difference value),
work indicator turn on. output relay connect. Load start to
work. When
RT
≤
ST
, work indicator turn off, output
relay disconnect, load stop working.
•
For example,set 10
℃
,difference 3
℃
,cooler work when
RT
≥
13
℃
.cooler stop when
RT
≤
10
℃
.
•
②
Heating mode:
HC set to H,use heater as load. When
RT
≤
ST
-
D
, work indicator turn on. output relay connect.
load start to work. When
RT
≥
ST
, work indicator turn off,
output relay disconnect, load stop working.
•
For example,set 10
℃
,difference 3
℃
,heater work when
RT
≤
