The set pressure is the pressure at which a relief valve starts to open. When the valve is open and relieving, the pressure will be higher or lower than the set pressure, depending on the system and the valve design. That is the blow-off pressure.

What is difference between design pressure and working pressure?
The working pressure is also referred to as the Maximum Operating Pressure (MOP). The MOP is the highest pressure expected during operation. The Maximum Design Pressure (MDP) includes the maximum pressure that is protected by relief valves in case of failure. For example, if the MOP is 100 psi and their are relief valves set at 10% above the MOP the MDP would be 110 psi.
Difference between bar and barg?
The 'g' added on to bar means 'gauge', as opposed to bara, meaning 'absolute'. The 'zero' of a normal gauge is normally set at atmospheric pressure (things like tire pressure gauges, water gauges etc.) These gauges will read as "10 bar" but really mean that the absolute pressure is 10 bar + atmospheric pressure (~1.01325 bar). Some gauges however are absolute gauges. These might include weather gauges, or gauges on closed processes. bara = barg + atmospheric pressure
What you mean by cold differential set pressure of a safety valve?
cold differential test pressure -The inlet static pressure at which a pressure relief valve is adjusted to open on the test stand. This test pressure includes corrections for service conditions of superimposed back pressure and/or temperature.
What is the difference between system overshoot and system lag?
System overshoot is the room temperature that is way over the set room temperature from residual heat from the exchanger into the room after it has shut off. System lag is when the temperature drops below the set point on the thermostat.
How boiler feed valve works?
There are automatic boiler feeder and manual feeds and depending on the desired working pressure required that would determine the "SET" pressure of the feeder
