Universal-XR Unit of Measure Change Instructions
1. General Description
The Model Universal-XR is a 71x29 mm format microprocessor-based controller. It is available in 12/24Vac/dc, 120Vac, or 230Vac versions and is suitable for applications on high, medium, or low temperature refrigeration units. It features three relay outputs to control the compressor, defrost (which can be electrical or hot gas), and evaporator fans. It can operate with PTC or NTC probes. If defrost is terminated by time, it can function with a single thermostat probe. If defrost is terminated by temperature, it includes 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 via the keypad.
2. Quick Start Up Procedure - Up And Running In 5 Easy Steps
This Quick Start Up section is designed to get you up and running with the minimum of fuss. Follow these 5 simple steps:
- STEP 1: Install the new Universal-XR per the installation instructions included with the controller.
- STEP 2: Turn on power.
- STEP 3: THEN WITHIN 1 MINUTE COMPLETE STEPS 3, 4 AND 5. Press the [Set] and [Down Arrow] keys for 3 seconds. The controller will automatically recognize and adjust itself to the type of probes connected. (The display briefly shows 'tPd' followed by 'ntC' or 'PtC').
- STEP 4: Press the [Auxiliary]/[Type Controller] key for 3 seconds. The setting of parameter 'tC' is displayed. Use the [Up Arrow] or [Down Arrow] keys to adjust to the required setting, then confirm by pressing [Set] (see Table 1 below).
- STEP 5: Press [Set] for 3 seconds until the [Celsius] or [Fahrenheit] icon starts to flash. Then, adjust the SET POINT using the [Up Arrow] or [Down Arrow] keys, and press [Set] again to confirm.
Notes:
- All probes must be of the same type, either PTC or NTC.
- Probes must be between -58 to 140°F for auto-recognition to work.
- If 1 minute expires before completing the 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).

Note: As you change parameter tC, defaults change and should be approximately correct for that application. However, it is strongly recommended to check all parameter default values listed in these instructions to ensure they suit your particular application and make further adjustments if necessary. Read the following sections for information about programming.
3. Typical Connections - For General Guidance Only
The following tables describe typical connection configurations for different control types (TC=1 through TC=7). These diagrams illustrate how to wire the Universal-XR controller for various refrigeration applications.
TC=1 Heating: Controls heating systems.
TC=2 Cooling, Off Cycle Defrost, Time Ended: For cooling with time-based defrost.
TC=3 Cooling, Off Cycle Defrost, Temperature Ended: For cooling with temperature-based defrost.
TC=4 Cooling, Off Cycle Defrost, Temperature Ended, Alarm Relay: For cooling with temperature-based defrost and alarm relay.
TC=5 Cooling, Electric or Hot Gas Defrost, Temperature Ended: For cooling with electric or hot gas defrost terminated by temperature.
TC=6 Low Temp, Elec. Or Hot Gas Defrost, Temp. Ended, Fan Control: For low-temperature applications with electric or hot gas defrost, temperature termination, and fan control.
TC=7 Open Map to be Configured for any application: A fully configurable mode.
Power Supply Note: 12/24Vac/dc units use Terminals 4 & 5 for power supply. 120Vac units use Line and Neutral.
Load Description: Load1 is always Compressor or Heat. Load2 is OAA and Load3 is OAb.
4. Parameter Table and Factory Default Settings
IMPORTANT: Always set parameter "tC" first. As you move "tC" between settings 1 to 7, all non-relevant parameters will be masked. After setting "tC", it will be possible to modify all other relevant parameters. Once the program is completed, you may want to save the parameter map to a Hot Key. If "tC" is changed after final programming, the parameters will revert to the defaults listed below.
WARNING: Always switch the power OFF and then ON at the end of programming to update any parameter changes. Make sure you connect the correct number of probes to suit the setting of parameter tC. Failure to do this will cause probe alarms.

8. Other Features of the Universal-XR
As well as the main digital display, there are some small icons on the front panel. These are used to indicate the status of the loads controlled by the instrument. Each icon function is described in the following table.
Table 7: Display Signalling Description
| Combination | Function | Meaning |
|---|---|---|
| ON | Light (AUX) output enabled. | [Auxiliary] |
| ON | Cooling enabled. | [Cooling] |
| FLASHING | Anti-short cycle delay in progress. | [Anti-short cycle] |
| ON | Fan enabled. | [Fan] |
| FLASHING | Delay time on fan activation is running (Fnd > 0) | [Fan delay] |
| ON | Defrost in progress. | [Defrost] |
| FLASHING | Drip time in progress (Fdt > 0) or delay on start defrosting is running (dSd > 0). | [Drip/Delay] |
| ON | Auxiliary output activated. | [Auxiliary Output] |
| ON | Energy Saving activated. | [Energy Saving] |
| ON | Thermostat override enabled. | [Thermostat Override] |

| ON | Programming mode. | [Programming Mode] |
| FLASHING | All measurement units are in Fahrenheit degrees. | [Fahrenheit] |
| FLASHING | Programming mode. | [Programming Mode] |
9. Thermostat Override (not available when parameter tC = 1)
For rapid chilling or freezing, the thermostat can be overridden by pressing the [Up Arrow] button until the [Thermostat Override] icon lights up. The compressor will run in continuous mode, for the time period set in parameter CCE. Normal operation will then resume automatically after the CCE is exhausted or when the CCS is exhausted (Continuous Cycle Set Point). The cycle can also be terminated manually by pressing the [Up Arrow] button again for about 3 seconds.
10. Defrost Types
| tC Parameter Value | Action |
|---|---|
| 1 | No defrost |
| 2 or 3 | Off cycle defrost by timer |
| 4, 5, 6 or 7 | Forced type of defrost: Electrical or Hot Gas |
Note: tdF = 0: defrost is electrical; tdF = 1: defrost is by hot gas.
11. Evaporator Fan Control (only when parameter tC = 6 or 7)
The fan control mode is selected by means of the "FnC" parameter:
| FnC Parameter | Action |
|---|---|
| C_n | Fans will cycle ON and OFF with the compressor and be off during defrost cycle. |
| O_n | Fans will run continuously, but be off during defrost cycle. |
| C_Y | Will switch ON and OFF with the compressor and be on during defrost cycle (*). |
| O_Y | Fans will run continuously and be on during defrost cycle (*). |
(*) Note: Fans will stop if the temperature value set in parameter "FSt" is exceeded. 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. When this period has expired, the refrigeration cycle commences but the evaporator fans remain off until Fnd (fan delay) times out.
12. Special Applications – Dead Band Control
12.1 Dead Band Control (Cooling & Heating) tc=7
With [oAb = db], the compressor relay controls cooling as normal, but the 3rd (auxiliary/fan) relay is used to control a heater. The value entered in parameter HY will now be set equal on both sides of the SET POINT. For example, if [HY = 1°C], that will create a 2°C Dead Band. At [SET POINT + HY], cooling switches on. At [SET POINT – HY], heating switches on. Either cooling or heating switches off when the temperature returns to SET POINT.
13. Alarms
| Message / Mode | Cause | Outputs |
|---|---|---|
| EE Flashing | Data or memory failure | Alarm output ON; Other outputs unchanged. |
| P1 Flashing | Thermostat probe failure | Alarm output ON; Compressor output according to parameters Con and CoF. |
| P2 Alternating with room temperature | Evaporator probe failure | Alarm output ON; Other outputs unchanged; End defrost is timed. |
| P3 Alternating with room temperature | Second evaporator probe failure | Alarm output ON; Other outputs unchanged; End defrost is timed. |
| HA Alternating with room temperature | High temperature alarm | Alarm output ON; Other outputs unchanged. |
| LA Alternating with room temperature | Minimum temperature alarm | Alarm output ON; Other outputs unchanged. |
| HA2 Alternating with room temperature | Condenser max temp alarm | Alarm output ON; Other outputs unchanged. |
| LA2 Alternating with room temperature | Condenser max temp alarm | Alarm output ON; Other outputs unchanged. |
| dA Alternating with room temperature | Door open alarm | Alarm output ON: Outputs re-start if parameter rrd = 1. |
| EA Alternating with room temperature | Generic external alarm | Alarm output ON; Other outputs unchanged. |
| bAL Alternating with room temperature | Serious external alarm | Alarm output ON; Other outputs OFF. |
13.1 Muting Alarm Buzzer & Relay
The alarm buzzer can be muted by pressing any button. The controller will briefly show the reset "rES" label. Parameter tbA defines how the alarm relay will respond to the muting of the buzzer:
- tbA = n: The alarm relay will remain active until the alarm condition is rectified.
- tbA = Y: The alarm relay de-activates when the buzzer is muted.
In either case, the display will flash an alarm label until the condition is rectified.
13.2 Alarm "EE"
The Copeland Universal-XR is provided with an internal watchdog verifying data and memory integrity. Alarm "EE" will flash after detecting a failure in data or in the internal memory. In this case, the alarm output is enabled.
WHAT TO DO:
- Cancel the alarm by pressing a key.
- Check the value of all parameters and restore correct values when wrong.
- Check the correct instrument operation and in case of further errors replace it.
13.3 Alarm Recovery
Probe alarms "P1", "P2", and "P3" start 30 seconds after a fault in a probe is detected; they automatically stop 30 seconds after the probe restarts normal operation. Check connections before replacing the probe.
Temperature alarms "HA" and "LA" automatically stop as soon as the thermostat temperature returns to normal values and when defrost starts. Temperature alarms "HA2" and "LA2" automatically stop as soon as the condenser temperature returns to normal values.
14. Removing Security Level Protection
It is possible to allow access to any parameter from Pr1 level. To do this, go into Pr2 as previously described. Scroll to the label of the parameter you require and then press the [Set] and [Down Arrow] buttons in quick succession. The decimal point LED will be on, indicating that access to this particular parameter is now possible from Pr1 level. Its label will now appear when in Pr1 programming level and its value can be altered. To restore security level protection, use the same procedure (the decimal point LED will go out after pressing both buttons).
15. Mounting
The Universal-XR should be mounted in a panel, in a 29mm (1.14") x 71mm (2.8") hole, and fixed using the special brackets supplied. Ambient temperature for correct operation is 32 to 140°F. Avoid places subject to strong vibrations, corrosive gases, excessive dirt, or humidity (20 to 85% non-condensing RH is the recommended working range). Make sure air can freely circulate through the cooling holes slots at the rear side of the controller.
16. Electrical Connections
The instrument is provided with a screw terminal block to connect cables with a cross section up to 2.5 mm². Before connecting cables, make sure the power supply complies with the instrument's requirements. Separate the probe cables from the power supply cables, from the outputs, and from the power connections. Do not exceed the maximum current rating for each relay; in case of heavier loads, use a suitable external relay.
17. Probes
It is recommended to place the thermostat probe away from rapid air streams to correctly measure the average room temperature. Place the defrost termination probe among the evaporator fins in the coldest place, where most ice is formed, far from heaters or from the warmest place during defrost, to prevent premature defrost termination.
