Mercury Coldroom Panel Installation Guide
The Mercury Range
From Resource Data Management
The Mercury Coldroom panel has been specifically developed to suit a variety of coldroom needs. The purpose developed enclosure has
a detachable display/keypad for applications where the main enclosure is required to be “out of reach”. The panel is available with or
without a main isolator switch. Each internal circuit has either fuse or circuit breaker protection.
Based on Mercury technology, the controller has parameters that give this product complete flexibility for controlling either produce (HT)
or freezer coldrooms (LT).
Coldroom lights can be configured for maximum energy saving by using a timer (local or remote) to enable the lights and using the “lights
on when door is open” feature. A front panel over-ride switch is available when the door needs to be closed and the lights are required to
be on.
NB – Please be aware new software builds are not compatible with some older versions of hardware. These can be identified by
controllers using V6.4 (E) / V6.3 (M) and below. With these older boards software V6.4 is the latest update.
Networks
The panel is capable of connecting to either a TCP/IP local area network (recommended) or a RS485 network or controlling in
standalone mode with no network output. The built-in communication options are determined by the part number of the coldroom panel.
See Parts Numbers section for more information.
For non network versions it is possible to connect the Coldroom panel to the following network interfaces: -
Description
IP Futura (Single Mercury to IP Interface)
RS485 Interface (Single Mercury to RS485 Interface)
Mercury IP Switch (IP support for 10 controllers)

Probe and Alarm inputs
Note: When wiring in the probes to the connector, ensure that the 3 wires fitted to the probe connector (not shown on the diagram below) are
not moved and remain firmly connected. These wires are used for the external digital inputs; door-open and entrapment. The resistors for
the digital inputs are already present on the PCB and therefore external resistors are not required to signal door-open and entrapment
alarms. The user only needs to configure the jumper switches (below), to identify what type of probe is being used when using the
additional switched resistor functions ‘Case Clean’ and ‘Plant Fault 1’ (see Switched Resistor Values).

Temperature at which the LLV or compressor will switch on
Differential temperature below the cut-in temperature. The LLV or lead compressor
switches off when below this temperature
Percentage of the Air-On temperature that is used to calculate the control temp. The
remaining percentage will be used on the Air-Off temperature
Example, P-03 set to 30%
Control temp = 30% Air-on + 70% Air-off
As above only applied to the display temperature
The EEV controller will attempt to maintain this superheat value
Allows the user to speed up the EEV on time. With 30 providing the quickest response and
1 providing the slowest response.
Allows the user to speed up the EEV off time. With 30 providing the quickest response and
1 providing the slowest response.
Allows the user to select either EEV control, EET control or EEV/EET control. Note the
Evaporator Temperature probe should be fitted to the coldest point in the evaporator.
EEV uses the superheat as its main reference with the cabinet temperature as a secondary
control.
EET use the cabinet temperature as its main reference.
EEV/EET uses cabinet temperature as the main control until the SH gets close to the SH
reference point, then it switches to EEV control, it switches back to EET control when the
SH reference is satisfied.
Local – Uses local probes
Rem1 – Uses section 1 pressure from plant pack selected OR If no plant pack can use
Mercury Switch pressure
Rem2 - Uses section 2 pressure from plant pack selected
Rem3 - Uses section 3 pressure from plant pack selected
See: EEV Control using Pressure
Sets the minimum valve opening level, during normal operation the valve will not go below
this level. (Default 10%)
IF used in conjunction with a Mercury Pressure Hub PR0018-PHI, remote pressure from
Plant Pack or local pressure from a daughter card, then the Minimum value should be set
at 0%
Sets the point at which the algorithm will go to the “EEV Problem” state due to the
superheat temperature. For example if this parameter is set to 0 Degrees and the
Superheat value falls to 0 degrees or below, for the duration of P-54, then the controller will
enter the superheat problem state.
Sets the valve open position when entering the “Superheat EEV Problem” state.
Sets the time the algorithm stays in the “Superheat EEV Problem” state.
Sets the valve opening % which is used after a defrost or when the controller exits a
problem state for, example Superheat EEV Problem state
Normally the valve during recovery will open to the last average position. This setting
allows for that value to be reduced by said percentage. For example if the average valve
opening is calculated as 80% and P-55 is set to 50% then the valve will open at 40%.
This parameter only takes effect when the controller is used in conjunction with a Mercury
Switch pressure application. When the Mercury Switch generates the MOP alarm the
controller reduces the maximum valve opening to this percentage. For example if this
parameter is set to 50% and the MOP alarm is generated then the maximum valve opening
will be limited to 50%. Therefore as the controller pulses the valve the maximum the valve
will open is 50%.
Note P-51 EEV Minimum opening overrides the valve output operation and the valve will
not pulse below this setting.
Please see MOP note.
Please note parameters P-51 through to P-57 should not be altered without first
understanding the effects they may have on the case operation. If incorrectly set they may
have undesired affects.

 When either P93 is reached or an OT alarm is present
Temperature for the above (P92) operation. Use the defrost probe.
This feature allows for coldroom fans to be stopped when the coldroom is down to
temperature thus saving energy. This feature is present in both the M and E software.
 Run – fans operate as per the normal control strategy.
 Pulse – When the LLV closes the fans will stop when the Fan Pulse On
parameter (P-78) time expires. The fans then remain off for the Fan Pulse Off
time (P-79). When the parameter Fan Pulse Off time expires the fans come back
on for the Fan Pulse on time. The cycle then repeats. The fans resume normal
operation if the LLV operates. The fans pulse on/off to ensure the circulation of
air within the coldroom.
 Off – When the LLV closes the fans stay on for the Fan Pulse On (P-78) time
before going off until the LLV next operates.

Placement of the temperature control probes is important when using this feature
The duration of the fans are pulsed on in Fan Control.
The duration of the fans are pulsed off in Fan Control.
This value is used in the event of a control probe fail; In the EEV control algorithm the valve
will remain at this opening until the probe fault has been cleared. Please note the incorrect
setting of this value may result in flood back causing damage to the pack compressors. Do
not adjust this parameter if you are unsure of the consequences. In M software this is the
value to which the LLV/compressor relay will be pulsed open/closed. For example if set to
2 minutes then the LLV will be open for 2 minutes and then closed for two minutes. This
process will continue until the control probe fail has been rectified.
Set to ‘0’ to disable. If the valve control temperature fails, setting the value in minutes will
turn on and off the valve for the stated time period. The valve will cycle on/off until control
has been returned.
Plant - when a fixed resistor is switched in across the appropriate input a plant fault alarm
is generated.
External Defrost - when a fixed resistor is switched in across the appropriate input then it
places the controller into defrost. See also P-40 for setup. If the defrost signal is continually
present after completing the initial defrost then the controller will resume refrigeration. If the
defrost signal remains active then the controller will initiate a defrost and generate a
missed defrost alarm when the no defrost time parameter expires. Subsequent defrosts will
follow the no defrost time until the defrost input is removed.
Time (in 1000 x hours) before the service icon (Spanner icon) comes on. The Run Hours
timer increments based on the number of hours the controller has been powered up and
running. Reset the spanner icon to off by changing this parameter to 0 and then back to the
desired service interval. This process also resets the Run Hours value to 0. To view the
current Run Time value refer to the I/O list.
When man trap input is activated the LLV closes and Fans are stopped. Normal operation
resumes when the mantrap input is deactivated.
 Off – Feature is not used
 Mode 1 – Case goes to “CO2 Load Shedding Case Off Mode”
 Mode 2 – Goes to Case Clean Mode
See: Load Shedding
Feature used for restricting access to settings menu via controller display. ‘0’ disables the

When defrost mode is set to “Local”, this is the start time for the 1st defrost
When defrost mode is set to “Local”, this is the number of defrosts per day equally spaced
from the start time.
If the controller misses a defrost command for any reason, a defrost will initiate after this
time has elapsed from the last defrost. Normally set to 1 hour over the normal defrost
period.
The defrost will terminate (defrost control relay off) when the temperature of the defrost
termination probe reaches this value.
If the "defrost termination" probe is not fitted, defrost termination will occur when: The "coil in" probe reaches the set point (If fans are selected as "off during defrost")
Or
The "air off" probe reaches the set point (If fans are selected as "on during defrost")
If the "coil in" probe is not fitted, the "air off" probe will be used.
Minimum time that a defrost will use (Defrost can’t terminate until this time has elapsed. If
termination temperature is reached during this period, the defrost control relay is turned off,
but the controller will not continue the defrost cycle until the end of the defrost min period)
Time period after defrost minimum that defrosts are allowed to terminate
A period after defrost max to allow the draining of any surplus water
The LLV is switched on at the start of this period to allow the temperature to recover to the
normal operating point. This period also inhibits the OT alarm.
Note that if the air-off temperature is still above the OT alarm setpoint when this period
expires, an immediate OT alarm occurs; there is not a further alarm delay.
Time period before the defrost min period to allow for a pump down
This parameter allows the fans start after a drain-down period to be delayed, either by time
(P-49) or when the temperature point (P-88) is reached. This parameter uses the same
probe strategy as the defrost terminate.
Time after a drain-down period before the fans start if P-86 is set to time
Temperature at which the fans start after a drain-down period when P-86 is set to
temperature.
Allows the user to set the fans on or off in defrost.
Note: If the fans are set to on in defrost, they will go off for the drain-down period and then
follow the P-86 rules.
Electric – Heater is turned Off when termination probe reaches termination temperature
Electric Cin – Heater cycles on and off in defrost min if termination probes reaches
termination temperature but then falls below it again
Turns the defrost hold feature on and off. When switched on, the controller can be held in
defrost until a remote command from the front end terminates the defrost and starts the
recovery process. Note: defrosts will also terminate when the defrost max time-out period
elapses. This command works in “Defrost Remote” only
Allows user to enable/disable defrost skip. This feature allows the controller to skip
defrosts. If the current defrost terminates on temperature then the controller will skip the
next scheduled defrost providing the previous defrost terminated before the defrost skip
time (P-96). Operates only when the controller is set to local defrost scheduling.
Time factor used in defrost skip. The previous defrost has to terminate before this value
expires to allow the controller to skip a defrost.
Delay after the door open input is activated before the alarm occurs. If P-81 and P-81 are
set to switch cooling and fans off when the door is open, this will be overridden.
This parameter is used to close the LLV or EEV if the door opens.

ID of Plant Controller being used to broadcast Suction Pressure
The Broadcast ID is derived from the Rotary Switch positions set on the Plant controller
which is providing the remote suction pressure.
Note: No two Plant controllers on a local area network can have the same rotary switches
positions set. This will have adverse affects on control.

Load Shedding
Used on CO2 sites for load shedding on CO2 Compressor Faults or CO2 Vessel High Pressure Alarms
Cases can be put into a “CO2 Case Off” mode which will open the LLV/EEV and stop the fans to reduce the load on the pack or to
reduce the CO2 vessel pressure
See: RDM CO2 load shedding user guide
EEV Control Using Pressure
There are several ways to use the suction pressure to calculate the evaporator in temperature
Mercury Switch (PR0018-PHI)
(P-17 set to Rem1) The Mercury Switch can be used for EEV control on an Island by island basis. A suction pressure transducer is
connected from the case Island to the 4-20mA input of the Mercury Switch and the pressure read from this transducer is converted to a
temperature based on the gas type being used by the system. This temperature is transmitted to each controller connected to the switch
and along with the suction temperature probe local to the controller, the superheat is calculated. Please note that RDM recommended
that the evaporator in temperature probe is fitted as the controller will use this to calculate the superheat in the event of a
communication loss with the Mercury Switch. P-17 allows for the use of this remote temperature provided by the Mercury Switch. Please
see the Mercury Switch user document (PR0018-PHI) for further details.
Remote pressure Direct from a Plant Pack Controller
(P-17 set to Rem1, Rem2 or Rem3 depending on which input the suction transducer is connected to on the plant controller, transducer
input 1, 2 or 3)
(P-30) set to ID of Plant Pack Controller (Rotary Switch Setting), (P-31) set to refrigerant type, (P-32) set to pressure units Absolute or
Gauge
Maximum Operating Pressure
Maximum Operating Pressure (MOP) support added to Coldroom software. In an EEV application the remote evaporator in value is
obtained from the Mercury switch on which the coldroom panel is connected. MOP is a remote command sent from the Mercury switch to
the coldroom panel to close the EEV valve when a predetermined pressure is reached. This MOP value is configured in the Mercury
switch setup. MOP is also used in the M software and although a remote evaporator temperature is not used the LLV can be closed
when the MOP value is reached.

Comments
The panel will display Pd (pull-down) just after switching on until the control temperature has been reached; where it will then display the
temperature (display temp)
The panel will operate in accordance to the parameters set.
Lights: If the lights have been set to a timer mode, the lights LED will flash to indicate the timer is running during an “on” period, the lights
will come on when the door is opened, or if the lights switch is operated.
The lights LED will be off during a timer “off” period and the lights will not come on when the door is opened. The lights can be switched
on during the off period by the panel light switch.
Note. When using the lights in “remote” mode, do not use a GP timer input over-ride function; it will conflict with the local over-rides and
door switch functions. When a person trapped alarm occurs the lights are forced on.
If either or both of the LLV and Fans are set to go off when the door opens, they will revert to normal operation when the door closes or
when the door-open alarm activates.
Network Configuration
The final section to setup is the network address. In all instances, this must be done before the controller is plugged into the site network.
The controllers have an auto-initialise function, which will automatically log the device onto the site network. If the wrong address has
been entered onto the network, you will have to reset the controller address by setting the address to 00-0, and then re-enter the correct
address. (You may have to deregister the wrong address from the home system as well).
To log the controller onto a network you must first connect the controller to a communications module if one is not already internally fitted
coldroom panel. This is either a: 


485 Legacy, or
IP Futura
Mercury Hub
Please check Part Numbers section to determine the communication module fitted.
485 Legacy module
485 legacy support the following protocol: 
Genus
Connecting a 485 legacy module to the controller will govern which set up screens are made available.

The 485A option shows a value representing either the name of the controller in a Genus compatible network.
The value shown is of the form 05-6. This means the controller would try to log onto a Genus compatible network using the name
‘RC05-6’.
The following options are also available when the network type is set to Genus compatible.
The gAdd option displays (in hexadecimal format) the underlying network address assigned to the controller when it was logged onto the
network.
The rLog option allows the controller to be logged back onto the network with its current name. The ‘rLog’ message will flash for
confirmation. Press the Enter button to execute the command, Up or Down buttons to cancel.
Fast Network Address Reset
The CLrA option will clear out the network address and name in the controller. The ‘ClrA’ message will flash for confirmation. Press the
Enter button to execute the command, Up or Down buttons to cancel.
To enter this mode, hold the Enter, Up and Down buttons together for approximately 3 seconds until the message CLrA appears on the
display. CLrA is the first option in the menu consisting of the following options:

Genus compatible then the ClrA message will not flash and the ESC option can be used to exit the menu.
IP Futura module
In an IP system there are two options


IP-L
IP-r
IP-L allows you to fix an IP address into the controller, which you would use when you are connecting the controllers onto a customer’s
local area network. This would allow the customer to view each controller using Internet Explorer
IP-r allows you to give each controller on the system a unique number. This number is then allocated a dynamic IP address by the
system DHCP server (such as the RDM Data Director)
IP-L
To configure the communication module for IP-L, set all three rotary switches to zero. The module should then be connected to the
controller.

Switched Resistor Values
For PT1000 probes use 820 Ohm switched resistors. For NTC2K and NTC2K25 probes use a 590 Ohm switched resistor. For NTC10K
probes use 2k7 Ohm switched resistors. For NTC10K(2) probes use 2k2 Ohm switched resistors. The resistors used must have a
tolerance of 1% or better and the resistor must have a power rating of 0.25W. For improved accuracy whilst using switched resistors
RDM recommend resistors with 0.1% accuracy are used. Note the switched resistor features will not function when using 470R or 700R
probes. When a resistor is switched across the appropriate input it signals to the Mercury to enable the switched resistor function
described for that input whilst still recording the probe temperature on the input.
Temperature range for all probe types is -49oC to +60oC for probe inputs which do not have a secondary function (switched resistors).
Inputs which have a secondary function are restricted to -42oC to +60oC.
Note: switched resistors will operate in LT (Low Temperature) and HT (High Temperature) applications using PT1000, NTC2K or
NTC2K25 probe types only. For all other probe types the switched resistor inputs will work in HT applications only.

Modifying controller states
During normal operation you can change the following states from the function menu
Fans Only “FAnS”
Selecting the Fans Only option will put the controller into the Fans Only state if the current state is not Fans Only. If the current state is
Fans Only then the controller will change to the Normal state. Selecting this option will exit the setup menu automatically. The display will
show “FAnS OnLy”
If a remote display with key switch is being used, this function can be invoked by turning the key switch to the fans only position (90
degrees clockwise) with parameter P85 set to "fans"
Case Off “CASE”
Selecting the Case Off option will put the controller into the Case Off state if the current state is not Case Off. If the current state is Case
Off then the controller will change to the Normal state. Selecting this option will exit the setup menu automatically. The display will show
“CASE OFF”
If a remote display with key switch is being used, this function can be invoked by turning the key switch to the case-off position.
(Clockwise 90 degrees) with parameter P85 set to "case"
Lights Only “Ligt”
Selecting the Lights Only option will put the controller into the Lights Only state if the current state is not Lights Only. If the current state is
Lights Only then the controller will change to the Normal state. Selecting this option will exit the setup menu automatically. The display
will show “Ligt OnLy”
Note. When lights are being used in “Remote” mode with a timing channel: If the controller goes offline, the lights are turned ON after a delay of 5 minutes. The lights will stay on until the controller comes back online where they will revert to the state of the timing channel being used.
Probe Offset
This feature allows each probe value to be modified by an “offset”. Offset values are from -10OC (-18OF) to +10OC (+18OF) and on a
channel basis. Example C1 = Probe 1.

Appendix 1
For later hardware revisions of Coldroom panels the Compressor/LLV and Defrost MCB/Fuse can be interchanged to allow the higher
rated MCB/Fuse, 20A, to be used on the Compressor/LLV relay output and the lower rated MCB/Fuse, 10A, to be used on the Defrost
relay output. By default the Coldroom panel ships with the 20A MCB/Fuse fitted to the Defrost relay and the 10A MCB/Fuse fitted to the
Compressor/LLV.
Changing the configuration of this part must be carried out by competent personnel. RDM will not be held responsible for any damage incurred to the
equipment through mishandling or faulty installation when carrying out this work. If unsure do not carry out this procedure and contact RDM Technical
Support for further assistance.
Instructions – MCB Variants
1)
Before working on this equipment, ensure that the device is fully isolated from any supply voltage, including connections to all relays and other
I/O connectors.
2)
Open the Coldroom front panel by unscrewing the screw fixings at the top right and bottom right of the panel door. If an Isolator
switch is fitted to the Coldroom panel then this must be in the off position before the door will open.
3)
Locate the MCB’s. Note a fixing plate is attached over the MCB’s.
4)
On the fixing plate a label is affixed indentifying each output and the current rating in Amps for the associated MCB for the
default configuration. Note the ratings of the MCB’s are marked on the side of the MCB and they should be checked to ensure
the current MCB rating and position matches that indicated by the label.
5)
To swap the higher rated Defrost MCB over with the Compressor/LLV MCB firstly unscrew the plastic washer for all four
MCB’s.
6)
Now remove the two screws at the top and bottom of the fixing plate.

7)
Remove the fixing plate. Swap the MCB in position “F5 Defrost” to “F1 Compressor/LLSV” and the MCB from “F1
Compressor/LLSV” to “F5 Defrost” taking note of the orientation of the MCB.
The image below shows the view of the Coldroom with the fixing plate removed.
8)
Ensure the MCB’s are securely fitted and the desired rated MCB’s are in the appropriate positions before re-inserting the fixing
plate.
9)
Now secure the fixing plate using the previously removed screws.
10) Reattach the plastic washers to the MCB’s.
11) A secondary label is supplied with the Coldroom panel and must be affixed to indicate that the MCB positions and therefore
ratings have changed for the Compressor/LLV and Defrost MCB.
12) Close the Coldroom panel door and secure the front panel via the two screw fixings.
Warning : Only the Compressor/LLV and Defrost MCB positions are interchangeable. No other MCB positions can be altered.
Instructions – Fuse Variants
1)
Before working on this equipment, ensure that the device is fully isolated from any supply voltage, including connections to all relays and other
I/O connectors.
2)
Open the Coldroom front panel by unscrewing the screw fixings at the top right and bottom right of the panel door. If an Isolator
switch is fitted to the Coldroom panel then this must be in the off position before the door will open.
3)
Locate the Fused outputs.
4)
Look at the PCB screen print to identify each output and the associated Fuse. Note the ratings of the Fuse are marked on each
Fuse and they should be checked to ensure the current Fuse rating is correct for the position in which the Fuse is fitted.
5)
To swap the higher rated Defrost Fuse over with the Compressor/LLV Fuse firstly remove the rubber cover on each Defrost
and Compressor/LLV Fuse.
6)
Now remove and swap the Fuse in position “F5 Defrost” to “F1 Compressor/LLSV” and the Fuse from “F1 Compressor/LLSV”
to “F5 Defrost”.
7)
Ensure the Fuses are securely fitted and the desired rated Fuse is in the appropriate position.
8)
Now reattached the rubber cover over each Fuse ensuring the fuse and holder is fully covered.
9)
Close the Coldroom panel door and secure the front panel via the two screw fixings.
Warning : Only the Compressor/LLV and Defrost Fuse positions are interchangeable. No other Fuse positions can be altered.
