The panel will display Pd (pull-down) just after switching on until the control temperature has been reached; where it will then display the
temperature (display temp)
The panel will operate in accordance to the parameters set.
Lights: If the lights have been set to a timer mode, the lights LED will flash to indicate the timer is running during an “on” period, the lights
will come on when the door is opened, or if the lights switch is operated.
The lights LED will be off during a timer “off” period and the lights will not come on when the door is opened. The lights can be switched
on during the off period by the panel light switch.
Note. When using the lights in “remote” mode, do not use a GP timer input over-ride function; it will conflict with the local over-rides and
door switch functions. When a person trapped alarm occurs the lights are forced on.
If either or both of the LLV and Fans are set to go off when the door opens, they will revert to normal operation when the door closes or
when the door-open alarm activates.
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).
To log the controller onto a network you must first connect the controller to a communications module if one is not already internally fitted
coldroom panel. This is either a: -
485 Legacy, or
IP Futura
Mercury Hub
Please check Part Numbers section to determine the communication module fitted.
485 Legacy module
485 legacy support the following protocol: -
Genus
