This forum has been designed as a Technical Support Hub for frequently asked questions we receive on the Air Handling products we supply.
Along with tutorials on navigating through our iSmart Air Handling Unit Software, this forum is home to troubleshooting guides for products such as CAREL, Belimo, Titan, Axio, Sontay and many more. Please get in touch if you have a query that you haven't found an answer to below.
Please, can you forward confirmation of how to make this change to the limits on the supply temperature of the AHU software? Our Unit is controlled on return temperature, however, we would like to implement a minimum supply and a maximum allowed supply temperature.
Press the PRG Button, navigate to Service menu --> Service Settings --> Password "0000" --> Thermoregulation --> Scroll down to Screen Gfc04 (visible on the top left of the screen). Make sure that on the last line of the screen the "Supply Limit" parameter is set to "High/Low". Once this step is confirmed, scroll down to Screen Gfc07 (visible on the top left of the screen). Here you would need to set the Minimum and Maximum allowed temperatures on the supply for both Summer and Winter conditions.
