The Mercury & Intuitive Range
From Resource Data Management
For Version Mob 1.0
The Mercury Mk2 Mobile controller is intended for use in refrigeration display cabinets with one or two integral compressors with each
compressor having a temperature probe fitted to enable the compressor to be stopped if a set (discharge) temperature is exceeded. The
controller will switch on one or two compressors based on the average of an air on and air off temperature probes and has outputs to
control lights, fans and defrost control. The lighting relay can be set to operate as an alarm relay if required. The controller also has an
inbuilt defrost timer and 7 day lighting control timer which can also be used to switch the cabinet off and on at specific times, this can be a
useful energy saving feature if the cabinet contains non perishable goods (such as drinks) and can be automatically switched off at night.
There is also a DIN rail mounted version, known as the Intuitive Mercury, which is designed to be used in a control panel or electrical
tray. This range has the same features as the Mercury Mk2 controller with additional benefits such as higher rated relays, each protected
by an integral fuse and fuse protection for the incoming power supply. All connections are plug in socket and there are multiple network
interfaces to choose from including Ethernet.
The controller supports PT1000, NTC2K, 470R, 700R, 3K, 5K, 6K, NTC2K25, NTC10K or NTC10K(2) temperature probes (note: probe
types cannot be mixed)

Switched Resistor Values
For PT1000 probes use 820 Ohm switched resistors. For NTC2K, NTC2K25 and 3K probes use 590 Ohm switched resistors. For 5K and
6K use 1K Ohm switched resistors. 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 +127oC for probe inputs which do not have a secondary function (switched resistors).
Inputs which have a secondary function are restricted to -42oC to +60oC. If the full temperature range is required on all inputs and no
switch resistor features are needed then please see Switch Resistor parameter P-19
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.
Setting up the controller
Access to the controller can be achieved several ways

Through the front mounted buttons

Direct access by PC into the side comms port. This requires the Communicator software package available free on the RDM

Description
Temperature at which the lead compressor will switch on.
Differential temperature below the cut-in temperature. The 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
Delay before the second compressor is switched on if the temperature is still above set-point.
Note – The lead and lag compressors swap after each defrost to even the run times.
Allows the user to set the compressor for a given number of starts/hour
Diff below the Cut-In Temp the lag compressor switches off.
Single Compressor Operation
To disable compressor B operation and use only a single compressor for control set parameter P-07 to 0.
This will allow the controller work with just one compressor (A) and ignore compressor B.
Allows the keys switch to be:  Single turn for case off (Case off mode)
 Single turn for Fans only (Fans Mode)
 Single turn for case off, double turn for fans only (Toggle mode)
Switches between using the air-on probe and the Logging probe. Note the control and display
temperature will still be a derivative of the weighted
Average of the control probe + Air-off probe
Turns on/off the switched resistor case off function
Allows the user to set the fans to turn off when:  A pre-determined temperature is reached (P93)
 When an over-temperature alarm is present
 When either P93 is reached or an OT alarm is present
Temperature for the above (P92) operation. Note the defrost termination probe is the source of the
temperature reading used in this feature. If the defrost termination probe isn’t fitted then a similar process
to P-44 is used.
This input can be used as a defrost termination probe (default) or as a monitor probe with an OT alarm

This changes the function of relay 3 from Lights (default) to an alarm relay. The alarm relay is energised
for no alarm. Use the NC and Common for “Loop make” on alarm or use the NO and Common for “Loop
break” on alarm.
Selects whether the switched resistor invokes either a Plant fault or an External Defrost.
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.
Enables switched resistors to be used for Plant Faults, External Defrosts, Case Clean.
See : Switched Resistor Values
Used to place the controller into Case Off when its lighting timer is in the off state. When the lighting timer
is in the on state the controller follows its normal control operation. This feature is disabled if the set point
(P-01) is below 6oC. Please note that when the controller is in case off all alarms are inhibited and all
outputs are turned off. Therefore care must be taken when enabling this parameter.
 Off – Feature is not used and only the controller lights relay follows the lighting timer status.
 On - Feature is in use and controller will be in Case Off whenever the lights timer is in the off
state.
 Unused – This selection has no effect and should not be used. Please select from either Off or
On. This feature operates in either Local, using controller RTC, or Remote, using Data Manager
GP timer channel, lighting applications.
 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
This enables the discharge stop on compressor A, if set to ON then the compressor will be disabled if the
discharge temperature is exceeded.
This enables the discharge stop on compressor B, if set to ON then the compressor will be disabled if the
discharge temperature is exceeded.
If a compressor discharge probe exceeds this value and P-30 and P-31 are set to ON then the relevant
compressor will be disabled.
This is the differential below the discharge stop value that the discharge probe temperature has to drop
before the compressor is enabled again.
This limits the running time of any compressor, once the compressor has exceeded this time period it will
be switched off for the period of the anti short cycle time (P-06)
If either compressor stops due to expiry of the Maximum Compressor Run Time then both compressors
will be disabled if P-35 is set to On.
Delay for the over and under-temperature alarms
Under temperature alarm set point. This alarm uses the control temperature.
Over temperature alarm set point. This alarm uses the air-off temperature.
Allows the user to set the logging probe mode:  Off
 Logging with no alarms
 Logging with alarms
Applies a damping factor. This can be used to make a standard probe have the same temperature
response as a logging probe.
Delay for the Logging probe over and under-temperature alarms
Logging probe under temperature alarm set point
Logging probe over temperature alarm set point
Monitor probe over temperature alarm set point
Allows the user to set the defrost mode:  Local (Uses the internal parameters P-41 and P-42)
 Remote (Requires a defrost schedule in the front end)
 External (uses a switched resistor in input 3 ). When this signal is present a defrost is initiated.
Note: - If the external defrost signal is not removed then the controller will defrost according to the “No
Defrost” time and a missed defrost alarm will be generated. See P-29 for external defrost signal setup.
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 2 hours over the normal defrost interval period.
The defrost will terminate (defrost control relay off) when the temperature of the defrost termination probe
reaches this value, if a defrost probe is not fitted then the air off program 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
start refrigerating until the end of the defrost min period)

Maximum time period allowed for defrosting if termination temperature is not reached.
A period after defrost max to allow the draining of any surplus water
The compressor(s) 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 – Defrost heater will go off during defrost min. period, if defrost termination is achieved, and will
stay off.
Electric CIn – Defrost heater will go off during defrost min. period if defrost termination is achieved but will
then cycle on and off around the termination temperature setpoint until the end of the defrost min. period.
Gas - If gas is selected, the compressor is kept running for the duration of the defrost cycle.
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 starts the recovery process.
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.

*The defrost relay will cycle around the termination setpoint during defrost min if defrost type is set to elec/cln, otherwise it will be off.
Defrost Type (P-91)
If P-91 is set to gas, compressor A is switched on for the duration of the defrost cycle.
Defrost Termination
Defrost termination will be when the temperature parameter "def terminate" has been reached on the "defrost termination" probe. If the
"defrost termination" probe is not fitted then the air off probe will be used.
Fan Delay after Defrost
The fans will come back on when: The fan delay time has elapsed if the "fan delay mode" is set to time
Or
If the fan delay mode is set to "temp", the fans will come on when the defrost termination probe reaches the fan delay set point,
or on the time parameter, whichever occurs first.
If the "defrost termination" probe is not fitted, the fans will come on when the air off probe reaches the control set point (If fans are
selected as "on during defrost")
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).
When logging a Mercury or Intuitive Mercury with an RS232 interface onto a network you must first connect the controller to a
communications module, this is either a 485 Legacy, RDM Wireless Mesh system, IP Futura or Mercury Switch. When using an Intuitive
Mercury controller, the controller has to have the correct network card fitted (see “compatible network interfaces”). For connection to a
Mercury Switch (Hub) or an external network interface, the standard fitment RS232 network card is utilized.
RS485 Legacy module / Intuitive Internal RS485 Network card
Connecting an RS485 legacy Module or an Intuitive Internal RS485 network card to the controller will govern which set up screens are
made available. Both modules support the “Genus” protocol only.

Wireless Mesh Communication Module
RDM Wireless Mesh System, please refer to the RDM Wireless Mesh Communication Module user guide, which can be obtained from
the RDM website, for information regarding connecting a controller to a Wireless Mesh network.
The value shown in 485A is of the form 05-6. This means the controller would try to log onto a Genus compatible or RDM Wireless Mesh
network using the name ‘RC05-6’.
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:
Display Option
CLrA
Clear the address/name from the controller
ESC
Exit Setup mode
Pressing the Enter button to select the CLrA option will cause the ‘CLrA’ message to flash for confirmation, if the network type is set to
Genus compatible. Press the Enter button to execute the command, Up or Down buttons to cancel. If the network type is not set to
Genus compatible then the ClrA message will not flash and the ESC option can be used to exit the menu.
IP Futura module / Intuitive Internal IP Network card
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 Manager)
IP-L
To configure the communication module or network card for IP-L, set all three rotary switches to zero. The module should then be
connected to the controller. In the case of an Intuitive Mercury controller where the network card is already fitted, the controller should be
powered off, all three rotary switches set to zero and the controller powered on.

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”. An alarm is generated, fixed delay of 1 minute, when the controller is placed into the Case Off state.
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 “LitS 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.
