9.4 Heating
9.5 Cooling
9.6 Water Sprayer Feature
The Heating output operates based on the Main Setpoint and works as follows:
-When the average temperature is below the value returned by [Relative Heating Temperature + Main Setpoint] the Heating output is turned
ON
-When the average temperature rises and surpasses [Relative Heating Temperature + Heating Hysteresis] the Heating output is turned OFF.
Example:
Main Setpoint:
Heating Relative Temperature:
Heating Hysteresis:
When the average temperature falls and stays below 25.0 the Heating output is turned ON. As the temperature rises and
surpasses 26.0°C ( ) the output is turned OFF.
The Cooling output is designed to operate a SprinklingAir-Cooling Evaporation System and it is controlled both by temperature and humidity.
- When the average temperature is above the value returned by “ the corresponding output
is turned ON in cyclic mode, according to the settings configured in the parameters and .
- When the average temperature falls and stays below the calculation this output is
turned OFF.
If at any time the Cooling is turned ON and air humidity surpasses the value configured in then the
Cooling output is turned OFF. The output is turned ON again only if the humidity falls below the calculation
.
Example:
Main Setpoint:
Cooling Relative Temperature:
Cooling Hysteresis:
High Humidity to Force Cooling OFF:
High Humidity Hysteresis to Restart Cooling:
Cooling output ON Time:
Cooling output OFF Time:
When the average temperature surpasses 40.0°C the Cooling output enters the cyclic operation (15 seconds ON 30 seconds
OFF). When the temperature falls below 39.0°C the output is turned OFF. If the air humidity rises above 80.0% RH
during the Cooling process, the Cooling output is OFF until the humidity falls below 75% RH
Humitech Super Water Sprayer feature operates two Water Sprayer outputs. Each output is turned ON separately,
according to the temperature or humidity. When turned ON the Water Sprayer outputs operate in cyclic mode
according to the times configured.
-When the average temperature is above the value returned by the Water Sprayer output is
turned ON in cyclic mode.
-If air humidity is below the value adjusted in , the corresponding Water Sprayer output will also be turned ON in
cyclic mode, regardless of the current average temperature.
The Water Sprayer output will be turned OFF when the following situation occurs:
The average temperature falls and stays below the above-mentioned temperature minus the
The air humidity rises and stays above the sum .
-If at any time the air humidity is above the value configured in outputs
will be turned OFF, regardless of the current average temperature.
- When turned ON the Water Sprayer outputs operate in cyclic mode according to the values configured in the functions
and .
Example:
Main Setpoint: 30.0°C
Water Sprayer 1 RelativeTemperature: 15.0°C
Water Sprayer 1 Hysteresis: 10.0°C
Water Sprayer 2 RelativeTemperature: 20.0°C
Water Sprayer 2 Hysteresis: 5.0°C
Water Sprayer 1 ON Humidity: 20.0% RH
Water Sprayer 1 OFF Humidity Hysteresis: 5.0% RH
Water Sprayer 2 ON Humidity: 8.0% RH
Water Sprayer 2 OFF Humidity Hysteresis: 10.0% RH
High Humidity to Force Water Sprayers OFF: 80.0% RH
High Humidity Hysteresis to Restart Water Sprayers: 5.0% RH
Water Sprayer output ONTime: 5 seconds
Water Sprayer output OFFTime: 10 seconds
When the average temperature surpasses 45.0°C ( ) Water Sprayer 1 output is turned ON. If the temperature keeps rising and

If at any moment the average temperature is below the main setpoint the Water Sprayers outputs will be deactivated.
surpasses 50.0°C (30.0°C + 20.0°C), Water Sprayer 2 output is turned ON. When the relative air humidity is below 20.0% RH Water Sprayer 1
output is turned ON. If humidity falls below 8.0%RH, Water Sprayer 2 output is turned ON.
When the average temperature is below 45.0°C ( ) and air humidity is above 18.0% RH ( ) the Water
Sprayer 2 output is turned OFF.
When the average temperature is below 35.0°C ( ) and air humidity is above 25.0% RH ( ) Water
Sprayer 1 output is turned OFF.
At any time during the operation, if the relative air humidity is above 80.0% RH both Water Sprayer outputs are turned OFF. Outputs can be turned
ON again when the humidity falls below 75.0% RH ( ). Water Sprayer outputs always operate in cyclic mode when turned ON:
.
alarm system is divided into two outputs: alarm 1 and alarm 2:
-Alarm 1 output is turned ON when any of the following parameters is alarmed:
The thresholds for parameter alarms can be configured at the functions
, and
WhenAlarm 1 output is turned ON it operates in cyclic mode according to the value configured at the functionAlarm .
-Alarm 2 output is turned ON always when a power outage occurs. Power outage detection time can be configured at the function
. WhenAlarm Output 2 is activated it remains ON (steady).

Alarm 1 output is turned ON when any of the following situations occurs:
-Average temperature above
-Average temperature below
-Air humidity below
The hysteresis for exiting High/Low Temperature Alarm condition is valid for both:
The hysteresis for exiting Low HumidityAlarm condition is
When turned ON alarm 1 output operates cyclic:
During a power outage the controller waits to make sure it is not a power spike/surge before turning ON alarm 2 output continuously.
Daily setpoint programs allow you to configure a Main Setpoint for each day of the program. This feature makes the controller automatically change
its Main Setpoint for each program day. Day counter is increased at mid-night and the total amount of days cannot be greater than 132. For the
controller to use this feature the operation mode selected must be “ ”.
Example:
Program 1 - duration:
Program 1 Main Setpoint:
Program 2 - duration:
Program 2 Main Setpoint:
Program 3 - duration:
Program 3 Main Setpoint:
Program 4 - duration:
When starting the program the controller is set to the setpoint of program 1: 30.0°C; at midnight of the first day, the day number changes from 1 to 2;
since program 1 duration is 2 days the setpoint for program 1 ( ) remains valid.
Day counter is changed to 3 at the next midnight; since the amount of days is already higher than the duration of program 1, the controller starts to
use the setpoint for program 2: 35.0°C.
When day counter reaches 6 days the controller starts to use the setpoint for program 3 ( ).
The last program configured in this example is the program 3 since the amount of days in program 4 was configured to 0 (disabled). Therefore the
program batch finishes when the counter reaches 10 days. The controller displays a message in the screen and remains in operation with the last
setpoint configured (37.5°C) until the user changes the controller operation.
The internal memory (datalogger) is used to store the following information:
- Sensor faults
-Alarms
- Operation mode
- Number of the program that is running
- Temperature setpoint being used
- Control output status
- Current temperature/humidity readings
