Mercury 6-5 Stat – Installation & User Guide 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 controller can be configured to operate selected thermostats from one temperature probe.
Mercury 6-5 Stat – Installation & User Guide 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.
Mercury 6-5 Stat – Installation & User Guide 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.

Mercury 6-5 Stat – Installation & User Guide Network Configuration The final section to set-up 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.
Mercury 6-5 Stat – Installation & User Guide Over-ride Operation The 5 Channel Thermostat can operate either from its internal channel time settings or from a network Data Manager GP Timer channel (P70 sets the mode either local or remote). If the 5 Channel Thermostat is set up to use the remote timing channels it reverts to local mode if network communications are lost for more than 5 minutes.
Mercury 6-5 Stat – Installation & User Guide Normal Operation During normal operation, the controller will display "on". If the 5 Channel Thermostat is on a network and online, the green network LED will be on. If any alarms are generated the red LED will light. The yellow LED has no function and will not light. Frost Detect The frost detect parameter is used to provide heating in an instance where the timer status is off. Each thermostat channel has its own frost detect value that can be configured.
