1. GENERAL DESCRIPTION
Model Universal-XR is a 71x29 mm format microprocessor based controller, suitable for applications on high, medium or
low temperature refrigeration units. It is provided with three relay outputs to control compressor, defrost - which can be both
electrical or hot gas - and evaporator fans. It can work with PTC or NTC probes. Where defrost is being terminated by time,
it can operate with just one thermostat probe. Where defrost is being terminated by temperature, it has an input for an
evaporator probe(s).
The Universal-XR is equipped with a flashing visual alarm and buzzer.
Each instrument is fully configurable through special parameters that can be easily programmed through the keypad.
2. QUICK START UP PROCEDURE – Up and running in 5 easy steps

Notes:
1. All probes must be of the same type, either PTC or NTC.
2. Probes must be at between --58 to 140°F for auto recognition to work;
3. If 1 minute expires before you have completed quick set up, either cycle the power OFF then ON to start the set up again or
enter Pr2 as per the instructions and adjust your parameter settings manually (see Section 9).

UNIVERSAL–XR60CX
Install the new Universal-XR per the installation instructions included with the controller.
Turn on power,
THEN WITHIN 1 MINUTE COMPLETE STEPS 3, 4 AND 5.
Press the "SET" and "DOWN" key for 3 seconds and the controller will automatically recognise and
adjust itself to the type of probes connected. (The display briefly shows tPd followed by ntC or PtC).
Press the "AUX/tC" key for 3 seconds and the setting of parameter tC is displayed. Use the UP or
DOWN keys to adjust to required setting then confirm by pressing SET (see table 1 below).
Press SET for 3 seconds until the °C or °F icon starts to flash, then adjust the SET POINT using the UP
or DOWN keys, then press SET again to confirm.

Questions and answers
The evap fan icon will not come on and no fan
Possible causes for the evaporator fan icon not coming on and the fan not working in a Dixell UNIVERSAL XR60CX include:
1. Fon = 0 and FoF ≠ 0 or FoF = 0: Fans are always off in both cases.
2. FSt parameter set too high: If the temperature detected by the evaporator probe is above the FSt setting, the fans remain off.
3. Evaporator probe (P2P) not present: If P2P = 0, the system may not detect the evaporator temperature, preventing fan operation.
4. FnC setting: Depending on the FnC value (e.g., C_n, o_n, C_Y, o_Y), the fan may be set not to run during certain conditions like defrost or compressor off.
5. Fan delay (Fnd): After defrost, the fan may be delayed for drip time.
Check these parameters to diagnose the issue.
