Hi Lance. Thanks for your comment. Our technical team have suggested the following: For the AH1-5 with SCL set to 1, the value displayed will show a decimal point between -9.9°C to 19.9°C. This means from -10°C to -50°C, there is no decimal point and from +20°C to +80°C there is also no decimal point. For a heating application that needs a decimal point, you would need a more accurate process controller. Usually for heating applications over 20°C, whole numbers - with no decimals - are sufficient. For the AC1-5 with SCL set to 1, then the decimal point is always there. However, ensure you use a thermocouple or a PT100 - as PTC/NTC probes have a tolerance themselves of approx.+/- 1°C. So if decimal points are needed then it must mean serious accuracy is required from the probe also.

@@HawcoCoUk Thanks for replying. It just seemed so random to have the decimal point for some of the range, but not the rest. I'm trying a Carel IR33 in PID mode now - will see how it goes.

Dear Kad Kadbrf Both the Carel Easy Cool and Carel Easy Freeze controllers are designed for refrigeration applications only. For a controller to be used at 37C, you would require a different kind of controller, such as the LAE AC1-5. Take a look at this video - ruclips.net/video/U17XnfOZsk4/видео.html - which explains more about the parameters of this controller - or visit our website for more details www.hawco.co.uk/en/refrigeration/controllers/lae/lae-panel-two-stage-thermostat The Hawco Team

@@HawcoCoUk thank you <3

Hi Susy Ar The default setting on a Carel Easy Cool controller is set to Celsius. To change this to deg F, first push and hold the set button to go into the parameters. (The default password for Carel is 22) Then, use the up or down arrows to find the probe setting you need, which is parameter /5. Select option 0 for Celsius and select option 1 for Fahrenheit. Press the set button to save the changes. Be aware that this will only change the display from C to F. It will not convert the temperature readings from Celsius to Fahrenheit. So for example, 20°C will be displayed as 20°F (it will not convert the set point to 68°F). I hope this helps. The Hawco Team

Hawco thanks so much. I wanna trying 😉

Hi Ravi The flashing eco light shows that the economy setpoint has been activated. The economy setpoint is a different setpoint that can be initiated during times when the cabinet is not being used (for example at night when a store is closed) If you wanted to deactivate this setting, you will need to navigate to the CNF folder. The parameter H31 controls the function of the UP key while the parameter H32 controls the function of the DOWN key. Either one of these will be set to 3 (which means economy mode activation). Press this key to activate or deactive the economy setpoint mode. Please remember any changes to any parameter in the CNF folder will require you to power down the controller or the cabinet and switch back on to fully save the new parameters. Hope this helps. The Hawco Team

Hi Antonio It depends on the temperature you are hoping to achieve but you can set a LAE AT2-5 controller to switch off by either time or by temperature, whichever is reached first. For example, the two parameters you would need are: The DLI parameter which controls the defrost end temperature The DTO parameter which controls the maximum defrosting duration If you need any further advice on a specific application, email technical@hawco.co.uk and we will try to help you. The Hawco Team

Thanks for your comment. The OSP parameter refers to the temperature value that should be added to the setpoint when using the economy function mode. You should engage and disengage the economy function mode manually through a pre-configured key or controller digital input. You can configure the down key to do this. In this case, you should set parameter H32 to “3”. After that, power the unit off/on via the isolator. Then the DOWN button can be used to manually turn off/on economy function mode. The same function can also be found with IDPlus 971 and IDPlus 974 controllers. Refer to the Eliwell instruction manual for the IDPlus range of controllers for full details - see bit.ly/2WlSuon. Details of OSP setting can be found on page 26 and the H32 parameter on page 29. Hope that helps. Get in touch with technical@hawco.co.uk if you need further advice.

@@HawcoCoUk Ok? I gather that from the manual but specifically how? If my setpoint (SET) is set at -19 Degrees C and I put in an OSP setpoint of +5 Degrees, how does it affect my E1 (enviroment probe) reading. Will the actual independant measured temp be -14 or -24?

For this scenario, the probe will look to increase the set point by 5 deg C. from -19C to -14C while economy function mode is active

@@HawcoCoUk Ok, now it makes sense. Thank you

Hi Holly. Thanks for your question. With medical fridges, we always recommend that you go back to the fridge manufacturer for any help like this. Hope they are able to answer your question. The Hawco team

@@HawcoCoUk thankyou

Hi Mohamed The parameter you want is SCL. With SCL set to “2: This means that a decimal point is not present (ie “20 deg c”) With SCL set to “1”: This means that a decimal point is present. This now means that what was once “20 deg c is now 2.0 deg c” However, if you ever change the SCL parameter from “2” to “1” (or vice versa) please ensure you check all the parameters as they will all be affected - ie HYS (hysteresis) was “05 deg c” is now “0.5 deg c” automatically!! Hope that makes sense. The Hawco team

@@HawcoCoUk..Thank you very much for your reply- I understand that if I put HYS at 1.0 and SP at 38 ° C this might give me an average temperature of about 37.5 ° C

Dear Mohamed Setting HYS to “1.0” is too small a tolerance for the controller and probe to read unless you are using a K-type / J-type thermocouple. If you are using an NTC or PTC thermistor, you should increase HYS to at least “2.0”. Hope that helps. The Hawco team

Thanks for your suggestion. We will produce a video explaining a PID system when we record our next set of videos. In the meantime, here is a link to the manual for the LAE AC1-5 that contains information on setting PID parameters for this controller. www.hawco.co.uk/en/media/bluelogic/legacyproducts_uploadfiles/l/a/lae-ac1-5-controller-instructions_6.pdf If you need any help with a particular application, contact us at technical@hawco.co.uk and we will do our best to help you.

Dear Timmy The defrost parameter (d0) allows you to choose the defrost type required, depending on whether an electric heater or the injection of hot gas is the method being employed. There are five options available, which are 0=heater; 1=hot gas; 2=heater by time; 3=hot gas by time and 4=heater by time with temperature control. You can download a technical leaflet about the Easy Freeze controller with all of the parameters on this page of the Carel website - www.careluk.com/product/easy-freeze If you have any further questions, contact us at technical@hawco.co.uk.

Could you confirm the model number of the Carel controller you are using. Then we can send the right instruction sheet to you which should help you with your issue. Thanks

@@HawcoCoUk Hi , I can't see the model number but it says Easy Cool

Carel use the model number PZD*SNP0E1 for their Easy Cool controller. Details of the controller can be found on their website here - bit.ly/32hN4e2 If you need to buy a replacement controller, they are available from the Hawco website at www.hawco.co.uk/en/carel-easy-cool-controller-for-normal Hope that helps.

@@HawcoCoUk Hi , can you plz make a video for how to program carel easy cool

Hi James The set point required should be between +8°C and +12°C, depending on the product (e.g. wine, beer, ale etc). Defrost cycles will be minimal as the evap temp will be above +1°C. The easiest way to set up your controller would be to start by applying one of the four standard defaults (AP1-AP2-AP3-AP4) which come with the Eliwell IDPlus 961.Then you can change the setpoint as required. The most suitable default application for a beer chiller is AP2. To find out how to load this default application, refer to page 14 of the IDPlus instruction manual which can be downloaded here - bit.ly/2WlSuon Then to adjust the setpoint to between +8°C and +12°C, refer to page 19 of the same instruction manual. A full description of the AP2 default parameters can be found on page 25. If you need any more advice, email technical@hawco.co.uk and we will do our best to help you.

Top stuff thanks a lot for the reply

Thank you for your comment. Every application is different and there are a number of factors you need to consider to get the right setting for your particular situation. If you can send some more details about what you would like to achieve to technical@hawco.co.uk we would be happy to try to help you.

Hi Diaa, Thanks for your question. To clarify, higher setpoint (SPH) and lower setpoint (SPL) is the range our target setpoint (1SP) can be selected between. It is good to set a higher and lower setpoint as it allows end users to change the setpoint (1SP) within the range or margin set up by the installer.
