Procon

2.0 Product Description (cont'd)

Comprehensive microprocessor control
The Procon 15, 25, 45 & 75 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 fl ame monitoring.
2) Water high temperature and fl ue gas high temperature safety cut out.
3) Modulation of the burner output in conjunction with operating temperature control.
4) Large LCD display screen with clear graphical notations which continuously display operation or fault
status.
5) In built weather compensation to provide direct-on-boiler VT fl ow temperature (if required).
6) Remote stored hot water temperature control.
7) In built 2 stage boiler frost protection program.
8) In built pump exercise program to avoid standstill seizure.
9) Range rate adjustment which allows the power to be set to accurately match the maximum needs of
the system, with the facility to set diff erent fi ring rates for heating and hot water generation.
10) Facility to connect optional matched control components which allow the boiler to control;
• A hot water priority system using a 3 port valve or primary charging pump, and hot water sensor at-
tached to a stored hot water cylinder.
• An additional heating circuit pump and 3-port VT valve (if required).
• A multi functional room temperature controller with separate heating and hot water time controls, night
setback, frost protection, and remote interrogation of the boilers' set-points and function modes.
Room Sealed Option
Utilizing a concentric fl ue system 125/80 mm
to take combustion air directly from outside the building. Horizontal and Vertical terminals sets are available.
Inherent safety is achieved by the negative pressure within the boiler case, which in the event of incorrect seal-
ing of the boiler case would result in safe inward air leakage only.
Alternatively the Procon 15, 25, 45 & 75 may be installed as a conventional fl ue, exhaust only, using an 80 mm
∅
OD Polypropylene fl ue gas tube and fi ttings to exhaust the appliance to a suitable fl ue terminal location,
either vertical or horizontal.
Extended fl ue pipe lengths
The excess pressure from the combustion system at maximum output is in the order of 400 Pa. This allows
for the Procon 15, 25, 45 & 75 to be fl ued over considerable distances providing a great deal of fl exibility in po-
sitioning the boiler.
Designed for ease of maintenance
The Procon 15, 25, 45 & 75 has been engineered for ease of maintenance, even the most major of service
operations being able to be completed easily and quickly without the need for specialist tools.
