The Mercury Range
From Resource Data Management
This documentation refers to the Mercury 6-5 - 5 Channel Thermostat
Description
The Mercury 5 Channel Thermostat has 5 thermostat functions. They can be configured for independent use,
where each function is controlled by an individual probe or the controlle r can be configured to operate
selected thermostats from one temperature probe. Each channel can be individually configured for heatin g or
cooling applications with a selection of parameters. There is a 7-day timer with two on and off’s. Included in
the controller is a frost detect parameter. This over-rides the timer function, when the timer is off, to begin
heating should the channel probe reach the frost detect value. The controller has the ability to use any of the
channels to operate as a timer. Each input can also accept over-ride commands as detailed later in the user
guide. Note:- the over-ride commands work only on channels selected as a thermostat, it has no effect if a
channel is set to operate as a timer.
The 5 Channel Thermostat can operate stand-alone or it can be networked through either an "IP" network
module or a Mercury IP Hub. The 5 Channel Thermostat supports PT1000 or NTC2000 or NTC2k25
temperature probes (note all 6 inputs are either PT1000 or NTC2000 or NTC2k25)
Configuration
There is one type of controller within the 5 Channel Thermostat (Type 1)
Display value Type M
1 5 Channel Thermostat
Network
The controllers are capable of connecting to a TCP/IP local area network or controlling in sta ndalone mode
with no network output.
To connect to a network you must add the correct communications module.
• IP Futura module - (Part No PR0016)
• Mercury IP Hub - (Part No PR0018)
Ensure that all power is
switched off before

Connections
All connections are made to the back of the controller. The diagram below shows the connection detail. Inputs
and outputs are assigned according to the chosen configuration. See
Specification for further details on
connections.
!
Do not connect an earth.
Input/Output Allocation Tables
An over-ride can be achieved by switching in a fixed value resistor in parallel with the probe inputs as shown
in the table below.
5 Ch Thermostat Description Alarm Action (Switched Resistor)*
Input 1 Probe 1 and Over-ride 1 Yes Over-ride signal 1
Input 2 Probe 2 and Over-ride 2 Yes Over-ride signal 2
Input 3 Probe 3 and Over-ride 3 Yes Over-ride signal 3
Input 4 Probe 4 and Over-ride 4 Yes Over-ride signal 4
Input 5 Probe 5 and Over-ride 5 Yes Over-ride signal 5
Relay 1 Thermostat Channel 1 N/A
Relay 2 Thermostat Channel 2 N/A
Relay 3 Thermostat Channel 3 N/A
Relay 4 Thermostat Channel 4 N/A
Relay 5 Thermostat Channel 5 N/A
* For PT1000 probes use 820 Ohm
For NTC2000 and NTC2k25 probes use 590 Ohm

Setting up the controller
Access to the controller can be achieved several ways
• Through the front mounted buttons
• Direct access by PC or palm top into the rear comms port. This requires a software package available
on the RDM website
• Through the RDM Data Director or Data Manager.
Set-up Mode
Set-up through front buttons
ENTER UP
DOWN
To enter set-up 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.

Recommended set-up method
If you are not connecting to a network and want to set up the controller through the buttons we recommend
you use the following order from the function menu.
rtc. Real time clock (This will automatically synchronise on network systems)
a. Use the up or down buttons to scroll through the display until the display reads “rtc”
b. Press enter. The display will show “t-1”. press enter again
c. Scroll hours up or down (0 – 23) press enter
d. Use up button to select “t-2”, press enter
e. Scroll minutes up or down (0 – 59) press enter
f. Repeat for t-3 (seconds 0 – 59)
g. Repeat for t -4 (Days up to 31)
h. Repeat for t -5 (months up to 12)
i. Repeat for t -6 (Year up to 99)
j. Use up button to display “ESC”, press enter to display “rtc”
Time clock is now set
type. view controller type
The controller Type is preset at the factory and cannot be changed.
a. From the function menu scroll to select type, press enter
b. View the type number 1
c. Press enter.
d. Scroll to select “ESC”
e. Press enter
PArA. Set/view parameters (This can be achieved at the network front end)
a. From the function menu scroll to select PArA
b. Pressing Enter while PArA is displayed will enter the parameter menu. The first parameter option
will be displayed as P-01. Pressing the Up or Down button will present the other parameter
options P-02, P-03 etc. See the parameter list below to find what parameter number corresponds
to which actual parameter. Pressing the Enter button will show the current value of the selected
parameter. Press Up or Down to modify the value and press Enter again to save the value. The
parameter list number will be displayed again. Two other options are present in the parameter
menu – dFLt and ESC. Selecting ESC will exit setup mode. Selecting dFLt will reset all
parameters back to the default values for the current type of controller.
