STRATA1
2.0 product description (contd)
energy saving
In addition to the extremely efficient burner and heat exchanger system employed in the Strata 1, each
appliance includes a modulating speed boiler primary pump.
This feature allows the boiler to self-maintain a 20°C ∆t across the heat exchanger, optimising the heat
exchanger efficiency and reducing also the electrical consumption of the pump motors. The result is a
seasonal increase in boiler efficiency of a further 7-10% and a reduction in pump electricity consumption of
up to 70%.
natural gas or LPG
Appliances can be supplied for use with natural gas (G20) or LPG (G31).
comprehensive microprocessor control
The boiler control panel includes a user friendly microprocessor control centre which manages the
entire function of the appliance and encompasses:-
1. Management of the essential safety functions of burner ignition and flame monitoring.
2. Water high temperature and flue gas high temperature safety cut out.
3. Modulation of the boiler output and pump speeds in conjunction with operating temperature control.
4. LCD display screen with two lines of text to continuously display operational or fault status.
5. In built weather compensator to provide direct-on boiler VT flow temperature (if required).
6. Remote stored hot water temperature control.
7. In built 2 stage boiler frost protection program.
8. In built pump exercising program to avoid standstill seizure.
9. Cold start boost facility.
10. PC compatibility with data logging which allows communication with the boiler via a lap-top computer
to review/modify operational parameters and access operational history as an aid to fault finding and
preventative maintenance.
11. Range rate adjustment which allows the power to be set to accurately match the maximum needs of
the system, with the facility to set a different firing rate for heating. Output to hot water self adjusts to
the heat transfer capability of the calorifier.
12. Facility to connect optional matched control components which allow the boiler to control a heating
circuit pump, HWS primary pump or diverter valve and an underfloor circuit mixing valve and pump,
plus the ability for the boiler to be controlled by a remote multi function modulating room unit.
Multiple boilers may be connected to a modulating Kaskade manager which further enhances the
operating efficiency of a larger load modular boiler system.
room sealed option
If required, the boiler may be installed to be completely room sealed, taking combustion air directly
from outside the building, using a 125/80 concentric air duct/flue duct system. Inherent safety is afforded
by the negative pressure within the boiler casing, which in the event of incorrect sealing results in safe
inward air leakage only.
extended flue lengths
The excess fan pressure from the combustion system is 100 Pa, which allows the appliance to be
exhausted using small diameter PPS plastic flue components, over long distances, allowing for complete
flexibility in boiler siting.
designed for ease of maintenance
Although compact, the Strata 1 does not compromise serviceability. The appliance has been engineered
to be easy to maintain with even the most major of service operations being able to be completed easily
and quickly with the minimum of tools.
guarantee
The heat exchanger carries a five year guarantee against manufacturing or material defect.
