1 General Warnings

1.1 Please Read Before Using This Manual

This manual is part of the product and should be kept near the instrument for easy and quick reference. The instrument shall not be used for purposes different from those described hereunder. It cannot be used as a safety device. Check the application limits before proceeding. Copeland Controls S.r.l. reserves the right to change the composition of its products, even without notice, ensuring the same and unchanged functionality.

1.2 Safety Precautions

• Check the supply voltage is correct before connecting the instrument.
• Do not expose to water or moisture: use the controller only within the operating limits avoiding sudden temperature changes with high atmospheric humidity to prevent formation of condensation.
• Warning: disconnect all electrical connections before any kind of maintenance.
• Fit the probe where it is not accessible by the End User. The instrument must not be opened.
• In case of failure or faulty operation send the instrument back to the distributor or to "Copeland Controls S.r.l." (see address) with a detailed description of the fault.
• Consider the maximum current which can be applied to each relay (see Technical Data).
• Ensure that the wires for probes, loads and the power supply are separated and far enough from each other, without crossing or intertwining.
• In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel with inductive loads could be useful.

2 General Description

The XR30CHC, 32x74x60mm format, is a microprocessor-based controller suitable for applications on medium or low temperature ventilated refrigeration units. It has 2 relay outputs to control compressor and fans, light or defrost. The device is also provided with up to 3 NTC, PTC or PT1000 probe inputs to control temperature, to manage the condenser and for visualization purpose. There are also two configurable digital inputs. By using the HOT-KEY it is possible to program the instrument in a quick and easy way. The controller has Bluetooth 4.2 connectivity.

3 Regulation

The regulation is performed according to the temperature measured by the thermostat probe with a positive differential from the set point: if the temperature increases and reaches set point plus differential, the compressor will start. The compressor will stop when the temperature reaches the set point value again.

Diagram: A graph showing temperature on the Y-axis and time on the X-axis. A line represents the temperature, with two thresholds marked: 'SET' and 'SET + HY'. The compressor is shown to turn ON when the temperature crosses 'SET + HY' and OFF when it crosses 'SET'.

4 Energy Saving Algorithm

4.1 Description

The device permits to set different temperature to be used during normal and reduced power use. The standard SET-POINT (SET) is used to maintain the temperature at a certain value when the energy saving status (ES) is not active. On the other side, when the ES status is active a different SET-POINT (SET_ES), higher than the standard one, will be used. The parameter HES will have to be set to change the regulation temperature according to the following formula: SET_ES = SET + HES

There are also two different differential values for SET and SET_ES, which are used for compressor cut-in and cut-out: when ES status is active the HYE parameter will be used instead of the HY parameter.

4.2 Basic Energy Saving Algorithm

The energy saving status will be always saved in the internal memory to resume previous operation if a power failure occurs. It needs the presence of a door switch to work (for example: i1F=dor).

4.2.1 Parameters Involved

• i1F or i2F: set as door input to monitor the appliance usage
• StE: interval to change from normal to energy saving mode
• EtS: interval to change from energy saving to normal mode
• HES: differential for SETPOINT when energy saving mode active
• HYE: differential for regulation when energy saving mode is active
• dS: interval for door opening detection
• LdE: light output controlled (OFF when energy saving mode is active)

Diagram: Two tables showing state transitions. One table shows transitions from Normal to Energy Saving mode, triggered by conditions like 'Pushing the DOWN button for 3 sec (if enabled)' or 'Door continuously closed for the StE time'. The other table shows transitions from Energy Saving to Normal mode, triggered by conditions like 'Controller in ES mode for the Ets time' or 'If the controller is in ES mode, it returns in Standard mode (normal set-point) after opening the door more than dS time'.

Note: The cycling mode (ES - Normal mode ES etc.) works if i1F=dor and EtS and StE are different from zero. If EtS=0 or StE=0, the controller will not change the operating mode, and it will be possible to change from the normal mode to the energy saving mode by using ES button or by setting i1F=ES.

5 Pull Down Function

The Pull Down is automatically activated:

• When the regulation probe temperature T is: T>SET+HY+oHt value in normal mode
• T>SET+HES+HYE+oHE value in energy saving mode

In this case, a different set-point value (SET+CCS) will be enabled. As soon as the room temperature reaches the SET+CCS value, the compressor will be stopped and the normal regulation will restart. NOTE: Pull Down function is disabled when CCS=0 or CCt=0.

The CCt parameter sets the maximum activation time for any pull down. When CCt expires, the Pull Down will be immediately stopped and the standard SET-POINT will be restored.

6 Condenser Fan

6.1 General Description

The condenser fan is can be managed by dedicated control. To enable it, a condenser probe must be selected by using par. FAC. Here follows the description of all the related parameters:

• FAC: to select the condenser fan probe
• St2: to select the condenser fan deactivation setpoint
• HY2: differential for condenser fan activation
• FCC parameter it can be selected the condenser fan working mode:
  • FCC=C-n: condenser fan will switch ON and OFF with the compressor and will not run during defrost
  • FCC=o-n: condenser fan will run even if the compressor is off, and will not run during defrost
  • FCC=C-Y: condenser fan will switch ON and OFF with the compressor and will run during defrost
  • FCC=o-Y: condenser fan will run continuously, also during defrost.

7 Defrost

7.1 Defrost Mode

Any defrost operation can be controlled in the following way:

• EdF=rtC: by using an internal real-time clock (only for models equipped with RTC)
• EdF=in: timed defrost, in this case a new defrost will start as soon as the idF timer expires

7.2 Timed Mode

Defrost control is timed only. A couple of parameters is used to control the interval between defrost cycles (idF) and its maximum length (MdF). During the defrost cycle is possible to select some different display indications by using the dFd parameter.

8 Digital Output Configuration

Depending on the model, one or more digital outputs (relays) can be configurated with one of the following functionalities.

8.1 ON/OFF Output (OAX = ONF)

In case of fault because of the thermostat probe, the start and stop of the compressor are timed through parameters CoF and Con.

When oAx=onF, the output is activated when the controller is turned on and de-activated when the controller is turned off.

8.2 Dead Band Regulation

With oAx=db the output can be used to control, for example, a heater element. It is used to implement a dead band regulation. If so:

• oAx=db cut in is SET-HY
• oA1=db cut out is SET

8.3 Alarm Output

With oAx=ALr the output operates as alarm output. It is activated every time an alarm happens. Its status depends on the tba parameter: if tbA=Y, the output is deactivated by pressing any key. If tbA=n, the alarm output stays on until the alarm condition recovers.

8.4 Activation During Energy Saving Cycles

With oAx=HES, the output is activated when the energy saving cycle begins.
