-58°F ~ 230°F
Set Value
Cut-off temp. When temp rises and reaches SV,
heating device will be turned off. When temp drops
and reaches SV, cooling device will be turned off.

Heating Differential Value
When measured temp PV < SV - Hd, the
controller turns on heating equipment.

0.1 ~ 25
Cooling Differential Value
When measured temp PV > SV + Cd, the
controller turns on cooling equipment.

Calibrate the reading
Optional. If measured temperature is 3 degree higher
than the real temperature, set CA=-3.

***Further explanation about Compressor Time Delay (PT):
The time delay is a way of over-riding the temperature sensor so that regardless of detected temperature the output
device will not turn on unless the specified time duration has elapsed. Under refrigeration mode, after the power is on, if
the measured temperature is higher than (SV + Cd), the device won’t start refrigeration immediately, but waiting for a
delay time. Delay time is calculated right after the moment refrigeration stops.
When the time interval of two refrigeration cycles is larger than the preset delay time, the device will start refrigeration
immediately. (For example, PT=2. It’s been 3 minutes when the temperature reaches the turn-on temperature again. The
fridge starts immediately.)
When the time interval between two refrigeration cycles is less than preset delay, the equipment won’t start refrigeration
until preset delay is satisfied. (For example, PT=5. Your fridge stopped 3 minutes ago. Although it’s now turn-on-
temperature, you have to wait 2 more minutes before your fridge starts again.)
