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)

Compatible Network Interfaces
Mercury and Intuitive Mercury controllers are capable of connecting to either a TCP/IP local area network, an RS485 Genus compatible
network, an RDM wireless mesh network or they can be used in standalone mode with no network output. To connect to a network you
must add the correct communications module. Connecting to any of these communication modules will automatically be detected on
power up and will affect the set up screens available to you.

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 +127oCfor 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
website
Through legacy front end panels on 485 networks
Through the RDM Data Manager.
Across an IP network. (Current controller IP address required)
Setup through front buttons
To enter setup mode, hold the Enter and Down
buttons together for approximately 3 seconds until
the message “Ent” appears on the display. Now
press the Enter button again to enter the function
menu. IO will be displayed. Scroll up or down to go
through the list.

Parameter Descriptions
Number
Parameter
Description
P-01
Cut-in Temp
Temperature at which the lead compressor will switch on.
P-02
Diff
Differential temperature below the cut-in temperature. The lead compressor switches off when below this
temperature
P-03
Control Weight
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
P-04
Display Weight
As above only applied to the display temperature
P-05
Lag Comp Delay
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.
P-06
Anti SC Time
Allows the user to set the compressor for a given number of starts/hour
P-07
Lag Cut Out Diff
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.
P-85
Key-switch Mode
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)
P-87
Control Probe type
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
P-90
Resistor Case Off
Turns on/off the switched resistor case off function
P-92
Fans temperature
mode
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
P-93
Fans Off Temperature
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.
