I have a problem with my CH/HW system. Here are the details before I get into the specific issue.
10 year old Ideal Classic boiler feeding a hot water tank/CH system
Lifestyle programmer unit with separate CH HW controls
Twin value setup, between HW and CH
Iflo wireless thermostat receiver hooked into the programmer unit
And now the problem.
Central heating has slowly been failing. A hard power reset of the whole system is required to get the boiler to give heating on demand. This started out at every couple of weeks, then more frequently, and now won't start up at all.
Hot water is fine, valve opens, boiler fire up, etc, etc.
I've replaced the programmer unit, and the problem is exactly the same. I've swapped the valve servos between the two valves, thinking one might be faulty, but still no change.
I'm down to 2 options now, the wireless receiver unit or a board/sensor on the boiler.
My immediate question is, when the wireless receiver requests the programmer to demand more hot water, should the electric flow between the programmer and wireless receiver unit even if the CH is off at the time? I've put a 240v tester on the cable, and nothing is flowing even though the green demand light on the receiver is active.
I'm not sure if the programmer is stopping the flow of electricity or the receiver is faulty.
It's going to be a lot cheaper for me to replace the receiver if it's at fault, but I don't want to fork out money if it's the programmer that's blocking the flow of electric to the receiver because the boiler is faulty.
Cheers, Rob.
