My Turbomax is taking 2 minutes to go into high fire for the hot water.
Open a tap on high flow wait 2 minutes hear the gas valve click into high fire,and temperature rises to whatever I have the stat set at.
Why the delay in going to high fire ?
Green light flashes as soon as tap is opened and boiler fires at low rate. Any pre-warmed water then dissipates and temp drops to 40.
Could it be the PCB. Aqua sensor ok presumably due to seeing green demand light flashing on tap opening. Gas valve only doing what it is asked,therefore must be a problem with whatever is giving the gas valve its information ie PCB ?
