LE R410a Operating Instructions Button and their functions SINGLE BUTTON FUNCTIONS BUTTON FUNCTION Type Controller menu: Keep this button pressed for at least 3 sec within 1 min after power on to enter the “Type Controller Menu” (tC) AUX output control: Switches the AUX relay output (if enabled as such). Manual Defrost: Keep this pressed for 3 seconds to start a manual defrost cycle. - Page 4 LE R410a Operating Instructions Other features of the Controller As well as the main digital display, there are some small icons on the front panel. These are used to monitor the loads controlled by the instrument. Each icon function is described in the following table. Display signalling description ICON FUNCTION...
- Page 5 LE R410a Operating Instructions Parameter FSt sets the fan stop temperature. This is the maximum temperature, detected by the evaporator probe, above which the evaporator fans will stop. Leave FSt above ambient temperature during commissioning to avoid fan short cycle. After finishing the defrost phase, there is a stand still drain time, set by parameter Fdt.

LE R410a Operating Instructions Mounting The Universal-R should be mounted in a panel, in a 29 x 71 mm hole, and fixed using the special brackets supplied. Ambient temperature for correct operation is 0 to 50°C. Avoid places subject to strong vibrations, corrosive gases, excessive dirt of humidity (20 to 85% non-condensing RH is the recommended working range). - Page 7 LE R410a Operating Instructions Parameter Table (and factory default settings) IMPORTANT: Always set parameter “tC” first. As you move between settings 1 to 7, all none-relevant parameters will be masked. After setting “tC”, it will be possible to modify all the other relevant parameters. WARNING!! Always switch the power OFF and then ON at the end of the programming to update any parameter changes.

- Page 11 LE R410a Operating Instructions Display visualisation Description outputs activation delay at start up; (0 to 255 min) time delay before any output relay activates following “power on”. Thermostat override: (0 to 990min; res. 10min) period during which the compressor will run continuously, irrespective of temperature. Setting this parameter to 0 inhibits this function.
- Page 12 LE R410a Operating Instructions Display visualisation Description Fan stop temperature: (-55 to 50°C or -67 to 122°F) temperature above which the evaporator fan stops (during the normal refrigeration cycle). Fan delay after defrost: (0 to 255min) the time interval between the end of defrost and evaporator fans starting. Runs concurrently with Fdt (Drain down time).
- Page 13 LE R410a Operating Instructions Display visualisation Description Alarm muting: 0 = Alarm relay remains active when the alarm buzzer is muted; 1 = Alarm relay is cancelled when the alarm buzzer is muted.

- Page 14 LE R410a Operating Instructions Display visualisation Description Differential for temperature condenser alarm recovery: 0.1 to 25.5°C or 1 to 45°F. Condenser temperature alarm delay: (0 to 255min) time interval between the detection of an alarm condition at the condenser and the relative alarm signalling.
