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
“coil in” probe reaches the control set point (If fans are selected as “off during defrost”)
Or
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.

RDM Wireless Mesh System (Wireless Mesh)
The
485A

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
