The boiler output will automatically adjust according to the requirements of the system. The Eco is designed to work with most central heating controls however we recommend the Alpha Comfort standard controls or the enhanced Alpha Climatic boiler energy manager further improving the system efficiency by varying the system temperature depending on the room temperature and heat losses.

On - In this mode the boiler can be switched between 'Summer' or 'Winter' settings by pressing the Summer/Winter button (item 2 in Fig. 1). Summer setting - The boiler will only provide hot water when a tap is turned on and the central heating will not activate even if requested by external controls (frost protection and pump cycle are still active).
Further protection for the mains water supply and heating circuit must be provided separately. If Alpha external controls are fitted, a frost protection setting is incorporated into the room thermostat activating the central heating when the temperature falls below 5°C.
Press the reset button (item 3 in Fig. 1) on the control panel to restart the boiler if the fault occurs again, make a note of the fault code and contact your installer or Alpha technical Helpline for further advice.

The terminal on the outside wall must not be allowed to be obstructed. If it is damaged, in any way, turn the boiler off and contact your Service Engineer. Note: The Eco boilers are high efficiency condensing boilers and when operating vapour will be emitted from the terminal. This is safe and quite normal.

11 OPTIONAL BOILER CONTROLS (if fitted) There is a range of controls available from Alpha to operate your boiler. In addition to the items listed below the Eco boilers are compatible with most controls available on the market. However to get the most comfort and efficiency from your boiler we recommend the Alpha Climatic controls with enhanced remote boiler functions and efficiency control.
