The above are the four working states of the chiller controlled by the intelligent temperature controller. Refrigeration and
micro-cooling state conversion time is the shortest, (about 5-10 seconds) and can be converted several times in one minute. If
the thermal load is turned on, the chiller mainly works in these two working conditions, which can precisely control the
temperature of the cooling water. (The actual test water temperature fluctuations of about 0.3 degrees or so). When the
thermal load is off, the water temperature will overshoot downward, and the refrigeration compressor will stop working when
it reaches the A0 set value.
Need to pay special attention to is; chiller condition conversion and water temperature changes between there will be a time
difference, the parameter A6 is to describe the system inertia of the relevant parameters, according to this parameter, the
controller can calculate the corresponding action in advance, reduce the water temperature overshoot.
Refrigeration Compressor: When the temperature rises to the water temperature set value + refrigeration return difference,
and the compressor protection delay over the set time, the compressor starts to work. The compressor stops working when the
temperature drops to the water temperature setting value - heating return difference.
Refrigerant Solenoid Valve:
(1). The compressor works, when the temperature drops to (equal to, below) the water temperature set value, and the
refrigerant solenoid valve cut-off duration has been greater than the time set by the state transition delay (A3), the refrigerant
solenoid valve on. When the temperature rises to (higher than) the water temperature setting value or above, and the duration
of the refrigerant solenoid valve is greater than the time set by the state transition delay (A3), the refrigerant solenoid valve
cuts off.
(2). When the compressor stops running, the refrigerant solenoid valve is on.
(3). When the compressor starts to work (startup), the refrigerant solenoid valve must be in the cut-off state (under normal
circumstances, this condition is satisfied).
Electric Heating Rod: When the water temperature decreases to below the water temperature setting value —electric
heating rod control return difference, the electric heating rod starts to work. When the water temperature rises above the water
temperature setting value - electric heating rod control return difference, the electric heating rod stops working.
2 Water Temperature Setting Value
When the thermostat operates in the constant temperature mode, the water temperature setting value is constant at F0,
just like an ordinary thermostat.
When the thermostat works in intelligent mode, the water temperature set value is variable as follows:
When the room temperature plus F1 is less than F9, the water temperature set value is equal to F9.
When the room temperature plus F1 is greater than F8, the water temperature setpoint is equal to F8.
When room temperature plus F1 is less than or equal to F8, or greater than or equal to F9, the water temperature set value
is equal to room temperature + F1.

(2) Alarm Conditions
See the setting code table:
Er1：Room temperature﹥Air temperature super high alarm value (F6 setting value);
Er2：Water temperature﹥setting temperature + refrigeration return difference F2+water temperature super high alarm F4
Er3：Water temperature﹤setting temperature-heating return difference A0-water temperature ultra-low alarm F5
Er4：Room temperature sensor short circuit or open circuit
Er5：Water temperature sensor short circuit or open circuit
Er2, Er3 to meet the power-on alarm delay (A1) or power-on forced cooling 30 seconds after the water temperature into
the target temperature band (i.e., between the set temperature and the set temperature).
(i.e. between the set temperature and the set temperature + refrigeration return difference F2) before the alarm will be
effective.
(3) Alarm Control Status
When there is an Er3 alarm, the cooling and heating relay will operate according to normal logic.
When the Er4 alarm occurs, the water temperature setting (F0) of the controller operates according to the factory setting.
(If the controller works in constant temperature mode, E4 does not alarm)
When the Er5 alarm occurs, the system should turn to a shutdown state regardless of the operation in that state.
(4) Alarm Stop Sound
In the thermostat alarm state, pressing any key can stop the alarm buzzer sound, but the alarm display will not stop until
the alarm conditions are eliminated.
(5) External Input Alarm: External input alarm signal, and meet the time delay setting A9 after the time, the display Er6, the
system control is not affected, the alarm beeper
The alarm buzzer will sound.
(6) When Er1-Er6 occurs, the alarm buzzer sounds, and when the mute alarm key is pressed, the buzzer stops sounding. The
alarm output relay is automatically reset when the fault is removed.
reset automatically.
(7) Whenever an alarm occurs (except Er3), the electric heating rod will stop working. When the alarm is lifted, the electric
heating pad will work according to logic.
4 Key Tone
There is a key tone when the controller key is pressed, and a short tone is prompted every time a key is pressed.
5) Power-up Display
After powering on the display flashes for 3 seconds while displaying the indicator and digital tube, and the buzzer sounds.
After entering the normal logic operation state.
6) Temperature Correction
Room temperature correction and water temperature correction, when the display (room temperature and water
temperature) temperature and the actual deviation can be adjusted A4, A5, for correction.
7) Power-on Processing
After the thermostat is powered on and after the power-on delay (A2) time, the thermostat enters the 100% full-power
refrigeration state for 25 seconds. Then only according to the actual air temperature, water temperature control chiller work.
(Note: This is the "power on forced cooling" function. If the water temperature is higher than the set value of the water
temperature after the forced cooling, the compressor does not need to stop when the heating is back to the difference. (This
function is designed to facilitate the maintenance work.)
