After the
Configuration-Service
screen is adjusted,
the
Home
screen will show zone-to-pump associated
wiring. Yellow and blue lines indicate which pump
each CORAYVAC
®
system is connected to within the
controller's logic.
Note:
Ensure the hardwired connections match the
connection within the logic. Repeat this configuration
for each controller on the network.
8.4 Zone Temperature Setpoints
Press any of the
'Zone #'s'
displayed on the
Home
screen to access the temperature adjustments for the
associated zone. If
'Zone 1'
is selected,
'Zone 1'
screen will be accessed.
From this screen, users can make adjustments to the
zone temperature setpoint, or override a schedule.
Adjust the occupied setpoint by pressing the up and
down arrows to the desired zone temperature dis-
played next to the flame icon.
Arrow Buttons

On Button Icon
Note:
The
<Configure>
icon will bring users to the
Configuration-Zones
screen. It is recommended to
create all schedules prior to adjusting the settings in
the
Configuration-Zones
screen.
Note:
Allow a few seconds after adjusting setpoint for
information to process before navigating away from
page.
Note:
Setpoint displayed also reflects any adjust-
ments made at the zone sensor. This is the "Effective
Setpoint". For example: If the setpoint is at 68 °F and
the user adjusts the setpoint to 70 °F at the zone
sensor, 70 °F will appear on the zone screen. Adjust-
ments made at the touchscreen will be from the base
setpoint (68 °F). If user, then turns up the tempera-
ture 2 F° more, it will show the adjustment from 68
F°- 70 F°, and then jump to 72 F° to reflect the zone
sensor adjustment.
8.5 Schedule Creation
To maximize comfort and system performance, it is
recommended to program your heating schedule in
accordance with your occupied and unoccupied
zones and schedule. For best results, keep your
night setback temperature within 5 °F to 8 °F of your
occupied setpoint temperature.
In the
Home
screen select
<Menu>
then select
<Schedules>
. A list of schedule objects numbered 1
through 4 will appear. The schedule object number
corresponds with each zone number. Each zone
should be programmed individually.
