4. REGULATION
4.1 REGULATION TYPES
Parameter “tMr” defines the management of the probe inputs for temperature regulation: 1. nu: not used. P1 will be used by default 2. LoE: regulation performed on the minimum value between selected probes 3. HiE: regulation performed on the maximum value between selected probes 4. AvG: regulation performed on weighted average of probes:
=
(01
1
+ 02 (01 +
2 02
+ +
03 03
3 + + 04)
04
4)
Where: · PAx (x=1,2,3,4): select the temperature probes to use (nP, P1, P2, P3 or P4) · C0x (x=1,2,3,4): weight value applied to each probe
Notes: · If probe PAx (x=1,2,3,4) = nP the respective probe is not considered · If probe PAx (x=1,2,3,4) is in error the probe number in error is not considered · If all selected probes for calculating the regulation temperature value are in error, the
compressor output will be controlled following par. Con and CoF.
4.2 SINGLE ONOFF COMPRESSOR 4.2.1 COOLING/HEATING ACTION
The regulation is based on the temperature measured by the regulation temperature value with a tolerance (HY) respect to the set point. · T > SET+HY (cooling) or T < SET-HY (heating):
output oAx=CP1 activation · T < SET (cooling) or T > SET (heating): output
oAx=CP1 deactivation
4.2.2 DEAD BAND
The regulation is based on the temperature measured by the regulation temperature value with a couple of differentials respect to the set point. · T > SET+HY: cooling output activation · T < SET: cooling output deactivation · T < SET-HYd: output oAx=db activation · T > SET: output oAx=db deactivation
Par. rAr set a delay between cooling and heating output activations and vice-versa.
4.3 DOUBLE ONOFF COMPRESSOR
This regulation can be activated when oAx=CP1 and oAy=CP2 and is valid only for ONOFF compressor. It allows the activation of the second compressor according to a step logic (2CC =HAF) or a parallel logic (2CC=FUL). Please refer to the complete manual for more information.

5. PUMP DOWN
PUMP DOWN process removes the liquid from the low pressure side, preventing liquid from entering the compressor during off-cycle and potentially damaging it. It requires a solenoid valve to close the liquid line. This function requires the following parameters to be properly configured:
· oAx (x=1,2,3…)=CP1 or CP2: a digital output set as “compressor” output · oAy (y=1,2,3…)=So1: a digital output set as “solenoid valve” output · Pdn=Y: to enable the PUMP DOWN logic · Pdt>0: maximum time for PUMP DOWN function · ixF (X=1,2)=LPS: low pressure contact to stop the PUMP DOWN · PdA>0: delay before signaling low pressure contact failure
6. PULL DOWN
The pull down activates the compressor with a different setpoint configurable by the parameter CCS and it is activated: · By pressing a button (bxt = CCt) · Automatically after defrost · Automatically after power-on if T>SET+CCS · Automatically 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 these cases, a different set-point value (SET+CCS) will be used. As soon as the room temperature reaches the SET+CCS value, the compressor will stop 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.
7. EVAPORATORS CONFIGURATION
7.1 EVAPORATOR DEFROST MANAGEMENT
The XER manages the defrost up to two evaporators and uses a combination of six different parameters (MdF, MdS, dFP, dSP, dtE, dtS). The following combinations are available:
1. One evaporator with single probe (MdF, MdS = 0, dFP nu, dSP = nu, dtE, dtS =0); 2. One evaporator with dual probe management (MdF, MdS = 0, dFP nu, dSP nu, dtE, dtS); 3. Two independent evaporators (MdF, MdS, dFPnu, dSP nu, dtE, dtS)
NOTE: If one of defrost probes is not present or in error, the defrost will depend on the second defrost probe (if present and functioning). If both probes are in error or not properly set, the defrost will end by time (par. MdF)
7.1.1 SINGLE EVAPORATOR WITH SINGLE PROBE
For this configuration it is necessary to select the respective defrost probe on parameter dFP and configure the maximum defrost duration on parameter MdF (0÷255 minutes). Parameters relative to a second defrost, like MdS and dSP must be set to 0 or nu. (not used)
7.1.2 SINGLE EVAPORATOR WITH DOUBLE PROBE
For this configuration is necessary to select the respective defrost probes on dFP and dSP (dFPnu and dSPnu), configure maximum defrost duration on MdF (0÷255 minutes) and set MdS =0. The defrost will be activated when at least one of the two probes (par. dFP and dSP) measures a temperature lower than its end defrost set point (par. dtE and dtS) and ends once both probes are above their respective temperature limits, dtE and dtS.
1592003110 XER-P STP EN v1.0 2025.06.25.docx
XER
16/29
7.1.3 DOUBLE EVAPORATOR
For this configuration is necessary to set the two different defrost probes through parameters dFP and dSP and the maximum defrost duration on MdF and MdS as found in the following table:
End defrost set Defrost timeout Evaporator probe Digital output
EVAPORATOR 1 par. dtE par. MdF par. dFP Relay oAx=dEF
EVAPORATOR 2 par. dtS par. MdS par. dSP Relay oAy=dF2
7.2 EVAPORATOR FAN MANAGEMENT
Evaporators fans are managed through the output set as oAx = FAn. The regulation probe must be configured through the parameter FAP (by default FAP = P2). The list of involved parameters are:
· FAP: to select the control probe · FSt: to select the deactivation setpoint · HYF: differential to restart after deactivation · FnC: to define the working mode:
o C-n: in parallel with compressor output and OFF during defrost. o O-n: always ON, OFF during any defrost o C-Y: in parallel with compressor output and always ON during defrost o o-Y: always on · Fnd: activation delay after any defrost
In case of two evaporators, the second fan will be managed by the output configured as FA2.
8. DEFROST OPERATIONS
Defrost operations can be intiated in the following ways: · 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 elapses
In both cases a dripping time can be configured with parameter Fdt.
8.1 DEFROST MODES
Defrost processes are terminated by time or controlled by a temperature probe. When controlled by temperature probe, its time can be optimized by setting od2 = Y (See section 9.3 Optimized Defrost). Available defrost types are: Available defrost types are: · tdF=EL: with an electric heater · tdF=in: by using hot gas cycle
8.1.1 ELECTRIC DEFROST (tdF=EL)
To use this function, one of the following resources must be configured: · oAx=dEF · oAx=HEt (Output for the electric Heaters) · dFP=P2 (Defrost Probe)
In order to have the Heaters (oAx=HEt) working for Defrost purposes, “Htt=dEF” must be configured.
See section 9.4 Heaters Element Control for details.
8.1.2 HOT GAS DEFROST (tdF=in)
To use this function, the following resources must be configured: · oAx=dEF (Output for the 4-way Valve) · dFP=P2 (Defrost Probe)

8.2 OPTIMIZED DEFROST
This function must have the presence of a temperature probe to control the end defrost temperature and to set par. od2=Y. During the defrost phase, the temperature will be monitored to detect the ice on the evaporator, caracterized by a period of constant evaporator temperature. If the MdF time expires before the end defrost condition occurs, the MdF timer will be reloaded once, leading to a maximum defrost time of 2*MdF.
NOTE: The correct position of the evaporator probe is of fundamental importance for this methodology of defrost time optimization It should be placed on the position with the most ice accumulation and where the ice tends to melt last to ensure the evaporator clear of ice once the defrost ends.
8.3 DISPLAY VISUALIZATION DURING ANY DEFROST PHASE
The par. dFd permits to change the display visualization: · dFd = rt: real time temperature · dFd = it: temperature at the beginning of the current defrost · dFd = SEt: set point value used during the current defrost phase · dFd = dEF: label “dEF” during the current defrost phase · dFd = Coo: label “dEF” during the current defrost phase and label “Coo” during dripping phase.
8.4 HEATER ELEMENT CONTROL
This function can be used for: · Avoid freezing of the door gasket in low temperature applications by activating a heating resistance. · Removing ice from the dripping pipes during defrost phase
The function requires: · A relay set as oAx=HEt · A timer (par. tHE) for the cyclical activation of the HEt outputs
The HEt outputs can be controlled with par. Htt: · Htt = nu: function disabled · Htt = dEF: activation of the output only during the pre-defrost, defrost and post-defrost (dripping phases). · Htt = tiM: cyclical activation defined by par. tHE (ON and OFF cycles of equal duration and equal to par. tHE). · Htt = dor: in addition to the cyclical activation defined by par. tHE, the HEt output is forced active for 120 sec after each door opening. At the expiration of 120 seconds, the cyclical activation defined by par. tHE restarts (with first cycle OFF).
9. CONDENSER FAN
To enable the condenser fan management it is required to set a condenser probe (par. FAC). Here are the involved parameters: · FAC: to select the control probe · St2: to select the deactivation setpoint · HY2: differential for restarting fan · FCC: to define the working mode:
o C-n: in parallel with compressor output and OFF during defrost. o o-n: always ON, stopped during defrost o C-Y: in parallel with compressor output and always ON during defrost. o o-Y: always on
10. AUXILIARY REGULATOR
The auxiliary output can be managed by digital inputs (oAx=AUS, ixF=AUS): the output is switched on and off following the relative digital input status.

10.1 AUXILIARY REGULATOR
The auxiliary regulator can be used to manage the auxiliary output. Here are the involved parameters: · ACH: type of regulation for the auxiliary output: Ht=inversely proportional (heating); CL=directly
proportional (cooling). · SAA: set point for regulation band. · SHY: differential for regulation band. · ArP: probe for auxiliary regulator. · Sdd: auxiliary output OFF during any defrost. · 2At: start-up interval at max.
