My Programmable Thermostat Has A Setting For Different Times- How Does This Work? ?

I think the default setting is 30 minutes; different times for different types of heating systems. I can hear a relay in the thermostat click when it turns on- it doesn’t turn off until the set point temperature is reached.
What is this time exactly? When the relay closes doesn’t the thermostat simply short the two wires connected to it together? Maybe the timers are for heating systems which use more than two wires?
