energy saving
In addition to the extremely efficient burner and heat exchanger system employed in the MICROMAT EC 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 125/70 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 MICROMAT EC 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 provided that
INIBAL corrosion inhibitor is used in the system and a service contract is in place with an RVR approved
service agent. Please contact the RVR Customer Care Department for details.
