: I have a HW series Trianco domestic hot water/condensing boiler...
: The heat will not come up unless there is a call for domestic hot water. This happened once before and once the "low limit" sensor was replaced it worked. Now, it is doing it again even after replacement of this sensor. Today will be the third time the service personnel are called back and I am wondering if this is a common problem and what the solution may be?
: The status lights on the control panel all look OK... when the uinit *does* turn on, it goes through the normal sequence and the boiler fires off.
: However, if the unit gets *cold* and you turn up the thermostat; (say in the morning when you get up and the hot water hasn't been on) the boiler will not run. If you turn on the hot water, just long enough to get it *hot* and then shut it off, the boiler will run through a normal heating cycle.
: Any suggestions?
