OPERATING INSTRUCTIONS
V-10 TOUCH SCREEN BOILER CONTROLLER
The Express – Loads screen displays a selection button for each of the 4
possible loads. All loads are set to OFF from the factory allowing the system to
be programmed to correspond to the installation’s specic wiring connections. If
Load 1 has been piped and wired - (Load 1 = P/V1 & Therm.1) to heat something
press the Load 1 button. Next, select the type of load being heated with Load
1; Reset Heating, Setpoint, DHW (Domestic Hot Water), or External control.
If Setpoint, DHW or External Control is selected a settings screen will be shown
with the values pre-programmed appropriately for typical residential applications.
If Reset Heating is selected then the emitter type must be selected and then
the settings screen will be displayed. The pre-programmed values should be
carefully reviewed to be sure they will work for the intended application. The
values can be changed if necessary by following the methods described in
section 1.3.2.2 Setting Screens in this manual. When all the values are set as
required, press Save at the bottom of the screen to save the changes and the
Select a Load Screen will return. Pressing the Back button will return to select a
Load Screen with no load type being assigned.
These steps can be repeated for all loads connected to the boiler.
Express Setup can be used at any time after the controller has been programmed
to reset or alter the current settings of a load or to add settings for a programmed
load. Outdoor design temperature can be adjusted in the Installer Menu.
1.5.3 Load Status
Touching one of the Load 1 to 4 buttons will bring up a status display screen
listing specic operational information about that load in real time. If a sensor
is not connected to the controller, for example a DHW sensor or the Outdoor
sensor then the display will show n/c for Not Connected. Cycles/Day is a running
tally of the number of calls for heat that load has received in the last 24 hours. In
general, fewer cycles per day = better efciency and usually better comfort.
Touching the Load Statistics button will access a status screen that will list run
time statistics for the boiler including specics for each load.
Load Proles will give access to screens for each load that show a bar graph
prole of the time the boiler is ring at various throttle levels.
1.5.4 User Setup
The User Settings screen is a combination menu and settings screen. Date &
Time, Overrides and Backlight are the three available menu buttons. The water
Tank Temperature can be changed by touching the entry box. Radio buttons are
used to select the Occupied status and Units.
On the Time and Date settings screen NTP Server or Internal can be chosen.
The controller must be connected to the Internet for the NTP Server selection to
work properly. Choosing NTP Server will make the controller, when connected to
the Internet; automatically update its internal clock from an Internet time service.
If Internal is selected then the time must be set manually. The Time Zone and
Auto DST should be set appropriately in either case.
