Temperature controller NA8810A+

Professional temperature controller with NTC sensor included. Features include simple operation and easy installation. The control is based on the on/off (ON-OFF) method with adjustable hysteresis. The regulator has a temperature measurement channel (T1) and a control output (30A). It is used both in refrigeration equipment and installations and in heating processes. It is used in the food industry, plastics processing and everywhere where it is necessary to regulate temperature in a reliable and economical way. We also recommend it to everyone planning to build a backyard smokehouse, for alcohol distillation and other home applications. The controller has dimensions of 78x33mm and is designed to be mounted in a 70x28mm hole in the board, using mounting brackets. The maximum thickness of the board must not exceed 15mm.

Technical data

Application:

HEAT mode

Example:
Set temperature (SET): 80,0°C,
Hysteresis (h): 1,0°C
In HEAT mode, the controller starts heating when the temperature of sensor T1 is lower than the set temperature - hysteresis [SET-h], and ends heating when the temperature on the chamber sensor is higher than the set temperature + hysteresis [SET+h].

COOL mode

Example:
Set temperature (SET): 2,0°C,
Hysteresis (h): 1,0°C
In COOL mode, the controller starts cooling when the temperature of sensor T1 exceeds the set temperature + hysteresis [SET+h], and ends cooling when the temperature at the chamber sensor is lower than the set temperature hysteresis [SET-h].

Example of application

The controller is used in the food industry (refrigeration chambers), plastics processing and wherever there is a need for reliable and economical temperature control. We also recommend it to everyone planning to build a backyard smokehouse, for alcohol distillation and other domestic applications.

Audible temperature alarm

NA8810A + controller has the function of signaling exceeding the temperature above the set T max value and below T min.
For parameters :

• U52 : Delay for audible temperature alarm.
• U53 : After power supply , delay for the first alarm signal ( 0=function disabled).
• U54 : T max Value that is added to the temperature task causing an audible top alarm if : T read >= T set +U54
• U55 : T min Value that is added to the temperature task causing an audible low alarm if : T read =< T set +U53

Below is an example of use:

D1 input:

When NO or NC contacts No.10 and No.7 are shorted or opened during the operation of the controller, the symbol "iA" will be displayed on the screen, indicating that the controller is locked in response to an external warning signal, which will cause R1 output to open and the buzzer to sound. Manual contacts, e.g. main switch or other external sensors, e.g. inductive, float, limit, optical, audible, etc. can be used to short circuit or open.

Parameters for input D1 (U60):

• 0: (off) NO normally open state (contacts 7 and 10 must be shorted to trigger the alarm).
• 1: NO - when shorted, locked until the "P" key is pressed
• 2: NO - unlocked automatically after opening the contacts normally closed state NC (to trigger the alarm it is necessary to open contacts 7 and 10)
• 3: NC - locked after opening until the "P" key is pressed
• 4: NC - unlocked automatically after shorting the contacts

U61: Delay for external alarm input D1
