than 25

, the compressor starts to cooling, and the auxiliary display shows

the objective cooling temperature as 15

; when the water temperature is

lower than 15

, the compressor stops to cooling, at the same time the

auxiliary display shows the temperature upper limit as 25

.

Remark: In advanced application mode, it is upper and lower economic
control mode to set 0 as R_CS parameter, 1 as R_CM parameter. Usually
it is not necessary for users to change.

Press Menu key

under working interface, then the auxiliary display

shows T00, and the main display shows setting temperature. After

parameters set, press Enter key

to save and press Menu key

enter into temperature control precision setting, now the auxiliary display
shows T01(temperature control precision), the main display shows the
precision of the temperature difference control, which can be set by Left-shift

key

, Add key

and Reduce key

.

Remark: Units with Start/Stop economic temperature control mode can
not working under single-point high precision temperature control
mode by setting R_CS and R_CM parameter.
3. Tracking control mode:

In this mode, the water temperature in the bath can be controlled via adding
another temperature sensor by configuration of the sensors’ port of the unit.
This temperature sensor can sense the temperature of the environment or

user’s

equipments. Please refer to Part 3.4 for detailed setting method.

Remark: Ordinary chillers are not available of tracking temperature
control mode function, it is optional for customers.
