I have an oil fired well mclain with baseboard heat. Woke up this morning, turned the thermostat on, heard the click but no heat. So far the only way I can get the pump to cycle water is if I use jumpers from the 120v input to the pumps inputs in the control box. Everything else works fine. I have hotwater in the house. The honeywell box is not even 2 years old. I took off the wires in the thermostat and crossed them and still nothing. I then used jumpers and crossed the thermo leads in the box and still natta.

Sounds like aquastat may need replaced.

What is the low limit and high limit set to. Low should be 20 degrees lower then high.
