Heater Demo Kit Instructions

Thank you for visiting All Flex!

You likely have received our heater kit and have come here to obtain instructions on how to utilize the kit.  We invite you to visit other pages of our site to learn more about our flexible heater product offering, our services, and how we can assist you with your thermal management needs.

This heater kit is intended to demonstrate closed loop thermal control so that you can become familiar with All Flex heaters and sensors and how they can potentially be utilized for thermal management in your products.

QUICK START INSTRUCTIONS

 

DESCRIPTION:
With this module you can intelligently control power to most types of electrical device based on the temperature sensed by the included high accuracy NTC temperature sensor. Although this module has an embedded microcontroller no programming knowledge is required. 3 tactile switches allow for configuring various parameters including on & off trigger temperatures. The on board relay can switch up to a maximum of 240V AC at 5A or 14V DC at 10A. The current temperature is displayed in degrees Centigrade via its 3 digit seven segment display and the current relay state by an on board LED.

  • Settings Chart
    Long press the “SET” button to activate the menu.
    Code Description Range Default Value
    P0 Heat C/H C
    P1 Backlash Set 0.1-15 2
    P2 Upper Limit 110 110
    P3 Lower Limit -50 -50

    P5 Delay Start Time 0-10 mins 0
    P6 High Temperature Alarm 0-110 OFF
    Long pressing +- will reset all values to their default

 

  • Displaying the current temperature:
    The thermostat will display the current temperature in oC by default. When in any other mode making no input for approximately 5 seconds will cause the thermostat to return to this default display.

 

  • Setting the trigger temperature:
    To set the trigger temperature press the button marked ‘SET’. The seven segment display will flash. You can now set a trigger temperature (in oC) using the ‘+’ and ‘-‘ buttons in 0.1 degree increments. If no buttons are pressed for approximately 2 seconds the trigger temperature will be stored and the display will return back to the current temperature.

 

  • Setting the parameters:
    To set any parameter first long press the ‘SET’ button for at least 5 seconds. The seven segment display should now display ‘P0’. This represents parameter P0. Pressing the ‘+’ or ‘-‘ buttons will cycle though the various parameters (P0 to P6). Pressing the ‘SET’ button whilst any of there parameters are displayed will allow you to change the value for that parameter using the ‘+’ and ‘-‘ buttons (see below). When finished setting a parameter press the set button to exit that option. If no buttons are pressed for approximately 5 seconds the thermostat will exit the parameter options and will return back to the default temperature display.

 

  • Setting the cooling or heating parameter P0:
    The parameter P0 has two settings, C and H. When set to C (default) the relay will energise when the temperature is reached. Use this setting if connecting to an air-conditioning system. When set to H the relay will de-energise when the temperature is reached. Use this setting if controlling a heating device.

 

  • Setting the hysteresis parameter P1:
    This sets how much change in temperature must occur before the relay will change state. For example if set to the default 2oC and the the trigger temperature has been set to 25oC, it will not de-energise until the temperature falls back below below 23oC. Setting this hysteresis helps stop the thermostat from continually triggering when the temperature drifts around the trip temperature.

 

  • Setting the upper limit of the thermostat parameter P2:
    This parameter limits the maximum trigger temperature that can be set. It can be used as a safety to stop an excessively high trigger temperature from accidentally being set by the user.

 

  • Setting the lower limit of the thermostat parameter P3:
    This parameter limits the minimum trigger temperature that can be set. It can be used as a safety to stop an excessively low trigger temperature from accidentally being set by the user.

 

  • Setting temperature offset correction parameter P4:
    Should you find there is a difference between the displayed temperature and the actual temperature (for instance if the temperature probe is on a long run of cable) you can make minor corrections to the temperature reading with this parameter.

 

  • Setting the trigger delay parameter P5:
    This parameter allows for delaying switching of the relay when the trigger temperature has be reached. The parameter can be set in one minute increments up to a maximum of 10 minutes.

 

  • Setting the high temperature alarm parameter P6:
    Setting a value for this parameter will cause the relay to switch off when the the temperature reaches this setting. The seven segment display will also show ‘—‘ to indicate an alarm condition. The relay will not re-energise until the temperature falls below this value. The default setting is OFF.
