2.3.2 LCD Display

Upon power-up, the LCD screen initially flashes a software release number
then switches to a Standby- display mode, showing real time data plus key
temperature target settings.
When there is a call for heat from any load, that load is identified at the Status
line (e.g. Heating – RFL (for radiant floor) in place of Standby). the target
temperature for the relevant load is conspicuously displayed while that load is
being handled.
NOTE: the status line displays those loads that are heating or calling for
heat. in this instance ("Heating 3DHW"), load 3 has been set up as dHW and
is actively heating, with no other loads calling for heat. if you saw ("Heating
3DHW C:1RFL"), it would indicate load 3 dHW is actively heating, while load
1 (radiant Floor heating with reset) is shown as requiring heat but awaiting its
turn. if a third load has been implemented and is also calling, the status line
display would expand to show the relevant details.

the controller provides for the display of further information (via the Load
Status Screen) plus three levels of access for the adjustment of control settings.
This is done to simplify the control interface for the user while retaining field
access to the full functionality of the system for the appropriately trained
heating professional. the split access feature offers a layer of security against
adventurous "finger trouble", including accidental adjustment to settings that could
lead to inefficient operation (e.g. excessive cycling) or dangerous conditions.
to access the Main Menu, touch any key. Move the cursor up or down using the
top and bottom keys.
the Load Status Screen offers a comprehensive summary of all settings and
actual readings for each heating load, eliminating a need to jump between
screens while doing an extended watch of boiler operation.
where the word "more" is displayed at the bottom or top of a screen, it is

possible to see more lines by moving the cursor in that direction.
