Advanced control with new Potterton boiler
Published: January 2012
Potterton Commercial’s Paramount Three wall-hung condensing boiler has a control system for three heating zones and a DHW cylinder to ensure compliance with Part L2 of the Building Regulations. The functionality of the control unit is integrated into the PCB of the boiler so that when installed in cascade as part of a modular heating system, a separate control box is no longer required. Installation is quicker, easier and less costly, and more zones can be added if needed. The lead boiler can control the others in the system and change around the lag and lead boilers to achieve uniform use and continuous running during maintenance. There are six outputs from 30 to 115 kW. Efficiency is up to 109% net with NOx emissions of less than 20 mg/kWh — exceeding Class 5. The aluminium/silicon alloy heat exchanger comes with a 10-year guarantee. The control system offers text display of operational status with built-in weather compensation, Summer/Winter changeover and time-control.
