ECO Tec control operation
(continued)
❏
Dual temperature sensors on boiler outlet, DHW outlet and flue,
providing redundant protection.
❏
Boiler is shipped with an outdoor sensor.
❏
Blower speed modulation to control boiler firing rate.
❏
Alarm relay on error/fault for use with an audible safety.
❏
Optional PREHEAT mode – Automatically maintains boiler water
temperature to reduce boiler reaction time on Combi domestic hot
water (DHW) draws.
❏
Select the mode of PREHEAT, between Off, Economy and High
Performance.
❏
ECO BOOST – Reacts to homeowner use to recharge boiler water
temperature once, if needed to reduce boiler reaction time on subsequent
Combi domestic hot water (DHW) draws.
❏
Select whether or not to use the ECO BOOST feature. If conditions are
met, the burner will continue to fire after Combi flow ends to recover
temperature within the heat exchanger.
❏
Blower calibration – allows fine tuning of blower control to reach purge
speeds faster, reducing time to heat delivery.
Sequence of operation
Figure 72, page 72 is a summary of the operating sequence for the
control.
s
The statuses shown appear in the display as the control cycles
the boiler. See Figure 76, page 76 for screen shots.
s
The display banner will be red if a problem has been detected.

control Priorities & Input/Outputs
s
For heating installations with multiple systems, the control uses
PRIORITIES to determine the order of operation of the systems.
The control’s MAX and MIN time settings determine the maximum
and minimum times a system will be operated before being turned
off to allow another system to operate. A typical example is DHW
priority — heat demand from the DHW system is given preference
over space heating, if set to use Priority 1.
s
The MAX ON TIME setting controls the maximum time a priority
will be allowed to run before switching to a lower priority’s call for
heat. The MIN ON TIME setting controls the minimum time a
priority will be operated before switching to a higher priority’s call
for heat, or the next lower priority.
s
Each PRIORITY has its own set of operating parameters. The control
prompts the user to select the system type (finned tube baseboard,
DHW, etc.) and is factory programmed with parameters suited to
each of these system types. The user can also choose CUSTOM to
create a system type.
s
The 120VAC power output to the boiler circulator is provided by
a terminal block located on the boiler’s control board. For each of
the priorities, the control can be setup to run the boiler pump or
to leave it off.
s
Each boiler has four input/output pairs (INPUT/OUTPUT 1,
2, 3 and 4). Control setup prompts the user to assign each of these
I/O pairs to a PRIORITY. The control then knows which system
(priority) to operate when the input receives a call for heat. On a
call for heat to an input, the control closes the corresponding output
(120VAC) and begins controlling the boilers according to the setup
for the assigned priority.
s
When multiple inputs are set up on the same priority, they will run
at the same time if the priority and inputs are active.
s
Temperature units – Select between using
°
F or
°
C.
s
Manual Reset High Temperature Limits – Set High Limit
temperature safety value.
s
Daylight Saving Time – Select whether your boiler will obey Daylight
Savings Time for your region.
