OPERATING INSTRUCTIONS
Handling the Touchscreen
The touchscreen responds to a light nger touch on the screen.
If the touchscreen is:
• Left unattended, the screens will step back one screen at a time in 10-minute
intervals. The pop-up windows will also step back automatically in 2-minute intervals.
• Not activated for a user-dened period (10 minutes by default), the Home screen dims
to save power.

Getting to Know the Controller’s
Interface
The slide bar (left side) allows the viewing of a list that is longer than the active
1
display area. For example, while editing a load in the installer menu, the list of
items is longer than the screen size. Simply touch and hold the slide bar until it
turns blue, and slowly drag it down to scroll down the list of items. You can also
tap the arrows at either end of the slide bar to move the bar up or down.
View button is available only in the Error Log to display minor errors, major
2
errors, or system faults associated with the logged error event.
The Up and Down arrows are available in the Error Log menu and enable you
3
to scroll through the list of event records, one at a time.
Left and Right arrows are available in the Load Proles screen to scroll
through the four separate loads plus the remote load if the boiler is operating as
part of a multi boiler network.
Typically the Save button saves the displayed settings and returns you to the
4
previous screen. However, in the Error Log screen, it gives you the ability to
save the error logs (e.g., to a USB).
Returns you to the previous screen without saving any changes. This button is
5
found at the bottom right on all Setting Screens and all menu screens.
Boiler Status Bar - Indicates if the boiler is in a normal, warning or alarm state.
6
When no warning or alarm state is present, the bar is green and the time is
displayed inside the green area. The bar can also display as yellow or red,
corresponding to a warning or to an alarm state. Text inside the bar indicates
the specic warning or alarm present. If more than one alarm is present, the text
display slowly rotates though the various alarm states.

OPERATING INSTRUCTIONS
V-10 TOUCH SCREEN BOILER CONTROLLER
Express Setup
Express Setup enables you to congure a boiler’s parameters using default values
including all the appropriate values to operate each load type under most operating
conditions.
Load Status
Load Status provides informational screens. For example, if you select:
• One of the Load 1 to 4 buttons:
• The status display screen lists 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), the screen shows n/c (Not Connected).
• Cycles/Day shows a running tally of the number of calls for heat that a load
has received in the last 24 hours. In general, fewer cycles per day equal better
eciency and usually better comfort.
• The Load Statistics button, a status screen lists the run time statistics for the boiler
including specics for each load.
• The Load Proles button, a screen displays each load, showing a bar graph prole
of the time the boiler is ring at various throttle levels.
User Settings
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 is changed by touching the entry box.
Date and Time Settings
On the Time and Date settings screen, you can choose NTP Server or Internal. The
controller must be connected to the Internet for the NTP Server selection to work properly.
For instructions, see “Setting the Date and Time” on page 37.
Temperature Overrides for a Load
In the Overrides screen, you can enable the override program set for each load. When
you select the Edit button you can set the override temperatures with corresponding start
and end times for each load by day of the week. There are two override programs for each
day of the week.
For instructions on conguring overrides, see “Setting Overrides” on page 34.
The Screen Backlight
OPERATING INSTRUCTIONS
The Backlight setting is a power saving feature. The Backlight Settings screen provides a
slide bar to set the screen backlight level (brightness). Also, the Dim Time setting controls
the length of time there is no interaction with the touchscreen before the screen is dimmed.

Installer Settings
The advanced installer can access:
• Settings for assigning load types to four Loads.
• Multi-Boiler to set parameters in a boiler to operate as part of a group of boilers at
a site. For instructions on how to set up multiple boilers, see “Networking Multiple
Boilers” on page 26.
• Load Combining to set parameters to enable the boiler’s Load Combining
(previously known as Load Pairing) feature. For instructions on how to combine loads,
see “Combining Loads” on page 30.
• System Settings to perform security- and backup-related tasks such as:
• Restricting access to areas in the controller with password protection.
• Changing the default venting material.
Diagnostics
The Diagnostics menu is a valuable tool for the installer and service provider. It provides
mostly information such as error logs to help identify problems.
Error Logs
Errors are logged and stored in the controller memory. An error record includes the date,
time, classication, type(s) and the state of key boiler operating parameters at the time
the error event occurred. The controller can store a practically unlimited number of error
records.
The Error Log screen title bar shows “Error Log: (record no) (total no. of error records)”.
If there are no error records logged the title bar shows “Error Log: 1/0” and the Date
shows as End of Log. An Error record includes all the errors present at the time of the
error event.
Error Conditions
If the sensors indicate that the boiler is operating outside its limits, an error condition
occurs. The controller records any or all errors dating back to the original power-up,
including the date and time of the error.
There are three types of error conditions:
• Minor Errors
Minor errors result when an abnormal condition exists that does not present an
immediate safety hazard. The boiler shuts o the fuel and enters an extended purge,
followed by the error cycle of 5 minutes for all conditions other than maximum ignition
trials (a modied Major error which locks out for 1 hour after 3 unsuccessful ignition
attempts). Following the purge, the fan and pump are stopped until the end of the error
cycle. Normal operation then resumes.

OPERATING INSTRUCTIONS
V-10 TOUCH SCREEN BOILER CONTROLLER
• Major Errors
Major errors result when a condition exists that may be a safety hazard. The boiler
enters an extended purge then the fan and pump are stopped. The boiler is in a
lockout, and must be checked and restarted by a service technician.
Exception: The Ign. Trials Exceeded error will time-out for one hour before the system
attempts re-ignition.
• System Errors typically relate to the touchscreen controller.
OPERATING INSTRUCTIONS
Users can:
• Display the error(s) present at the time of the error event.
• Clear (delete) all error log entries.
• Save an error log to an SD card or USB ash memory, inserted into the controller.
For a list of errors and their xes, see “CHAPTER 5 Troubleshooting” on page 49.
Sensors Status Screen
The Sensors status screen displays the current active value for each of the temperature
and pressure (e.g., water Flow Rate, VS Load Duty Cycle and the Altitude) sensors.
If a:
• Temperature sensor is not connected to the controller the text ‘n/c’ is displayed.
• Pressure sensor is not connected to the controller ‘0’ is displayed.

The Advanced Diagnostics menu screen includes the following advanced level
selections for the experienced installer.
• The Display Parameters screen lists key operational parameters and their current
readings.
• The ATD Channels screen lists the raw, unltered input values from the analog
inputs.
Note
Users can:
• Clear Errors. This function clears any currently latched error states and forces the
controller to reassess the boiler’s error status and determine if any error state is still
present. We recommend using this method to clear errors because it is faster than a
power cycle.
• Perform an update to the controller’s software via an SD memory card, a USB
memory stick, or the Internet. For instructions on updating software, see “CHAPTER 4
Updating the Software Version” on page 45.
• Initiate a full boiler controller restart. A restart takes approximately two minutes to
complete.
• Reset factory defaults. This function returns all boiler operating parameters to their
factory default settings except for the Network and Date & Time settings. The error log
and operating history are not cleared. Reset Factory Defaults will take approximately
two minutes to complete.

Other Operating Features
Prioritizing Loads
When more than one load is dened, you can prioritize a scheduling routine to manage the
boiler’s operation. Typically, loads declared as DHW receive signicant - but not absolute
- priority. Multiple heating loads - with varying temperature targets - are run sequentially as
opposed to simultaneously (with a mixing valve).
The objective is to serve each load at the minimum possible temperature, as opposed to
running hot then mixing down (with hardware), saving the related hardware and fuel cost.
The approach optimizes the low temperature combustion benets of direct cool running of
a radiant oor. The large throttle turndown range coupled with outdoor reset means that
several loads can receive heat in turn, with less on/ o duty cycling than would occur with
other heat sources.
Default Values for Dened Loads
The boiler is shipped with default values for each type of declarable load (e.g., DHW,
radiant oor). The preset variables for DHW (a value of 85-87 on a 20-90 scale) give it
substantial priority, which declines over time if another load is calling. Spacing heating
loads (with Outdoor Reset) are given default values starting at a low of 28, while other
Set Point loads start with 62. Over time, such points are transferred between the loads in
accordance with the system rules.
The boiler automatically shifts between loads once the points totals reach an upset value.
Upon a load transfer, the burner modulates down to its base level and will then throttle up
as required for the new load. If competing loads have not been satised at the load switch
stage, the controller registers the ring rate and returns rapidly to the rate on the next
rotation.
Heat-apportioning can be changed in the Installer Settings input section.
Example: If baseboards (set up with Outdoor Reset as Load 3) are not providing the
desired heat, the on-time of the baseboards can be increased by increasing the Priority
value relative to the other declared channels (e.g., moving the Load 3 preset value from
43 to 50 or reducing another load’s value). Temperature targets for the under-served load
can also be raised in this example.
The basic function is that the dierence between settings equals the run time (in minutes,
for the initial cycle) of the higher load setting before switch-over to the simultaneously
calling load, e.g., DHW with priority set to 80 will run for about 35 minutes before switching
to a clashing load set with priority 45. Following the initial cycle, the competing loads will
switch back and forth after a further 10-minute interval pending satisfaction of one or both
loads.
To cause repeated unequal run times (for example, constant 35 vs 5 minute runs) you
need to integrate an external load removing relay or timer on one of the heat calls (contact
the Factory for details). Do not set each load to the top value, and in general, avoid equal
ratings.

V-10 TOUCH SCREEN BOILER CONTROLLER
Reset Heating
The boiler oers reset heating or outdoor reset control as standard equipment. Reset
heating coordinates the control of boiler supply/outlet water temperature for space heating
with the outdoor temperature.
Note
Reset Heating uses variable supply water temperatures to compensate for the diering
rates of heat loss that a building experiences as the outdoor temperature changes. For
any outdoor temperature above the coldest day expected, reset heating automatically
uses lower heating temperatures than would otherwise be used. This saves energy
without sacricing comfort.
OPERATING INSTRUCTIONS
When applied within a condensing boiler, outdoor reset control oers direct and signicant
combustion eciency benets by allowing generally lower circulating water temperature.
This provides cooler return water to the boiler, promoting more condensation (= energy
capture).
Contacts are provided for connection of an outdoor sensor (shipped with each boiler) to be
placed in an appropriate outdoor position (typically on the north face of the building away
from any heat source). The temperature management algorithm exes the boiler supply
temperature according to heating curves that are automatically called up through the load
declaration process.
15
V-10 TOUCH SCREEN BOILER CONTROLLER
Open Loop Reset System
In an “open loop” reset system, a room or zone thermostat is used to send a call for
heat over a 24VAC lead. This opens the respective zone valve, and signals the boiler to
re using onward leads to the boiler’s dry contacts (use one of the connections marked
“Therm 1, 2, 3 or 4” on the TB2 terminal strip). Gang such leads in parallel from multiple
zone valves for single connection to the boiler. Note that typical room thermostats simply
provide a call for heat. They do not control the circulating water temperature from the
boiler in an open loop reset system. Adjustment of a room thermostat from 72°F/22°C to
86° F/30°C will make no further dierence to the delivered temperature if the oor slab has
stabilized at the boiler temperature determined by the reset curve.
Outdoor Reset
Where outdoor reset is applied without the indoor sensor feedback option, some manual
adjustment may be required to achieve the desired comfort level.
Note
Fine adjustment can be made by editing the Indoor Setpoint ° variable, on the Reset
Heating settings screen. To increase heat (e.g., from 72°F/22°C to 74°/23°C) move the
Indoor Setpoint ° value upward (warmer) from the level otherwise chosen. This shifts the
position of the reset curve, and adjusts the boiler water temperature by a similar amount.
Do not adjust the Design Indoor ° value. Moving the Design Indoor ° value upwards with
the Indoor Setpoint ° adjustment will be ineective.
Optional Indoor Temperature Sensor
An optional indoor temperature feedback routine can be activated with the installation of
an indoor sensor, connected to the designated TB2 contacts to automate adjustment of
the outdoor reset routine.
Note
The key inputs on initial setup are:
1. Design Outdoor °
– the coldest expected outdoor temperature typically experienced
at the installation site.
2. Design Supply °
3. Design Indoor °
Setpoint °
– the desired boiler outlet temperature to occur on the coldest day.
- the temperature value that anchors the reset curve. The
Indoor
setting is the primary means for the user to “bias” the outdoor reset routine
to add or reduce heat.
16
4. Summer Shutdown - this value is essential for the reset curve to calculate the
correct water temperature.
If Reset Heating is selected and there is no signal received from the Outdoor Sensor, the
controller assigns a provisional 32°F/0°C value and adopts the appropriate temperature
target from the relevant reset curve.
