I can think of two possibilities. First, the relay is controlled by a thermostat somewhere, which wasn't set to provide heat.
Second, the circuit is shared with some other high-power device, such as maybe the water heater electric element, and the relay switches between the two loads. This would presumably be done as a sort of load shedding to avoid overloading the shore power connection (which I would guess is a 30A connection in this case) and popping the main breaker etc.
