I have a new Pelonis oil filled heater and a new Herpstat HP. The heater has three settings that correspond to 600W, 900W and 1500W. When the heater is connected to the thermostat, any setting other than the 600W cause the thermostat to restart. My guess is the startup current is exceeding the capability of the relay in the thermostat, but I have a hard time understanding why that's the case for the 900W setting. I'd be fine with using the 600W setting, but I'm not sure at this point whether that's enough heat to keep my room warm. Anyone have any ideas on perhaps what I'm doing wrong or what else could be the issue?

I have the heater connected directly to the outlet on full power right now and it hasn't tripped my 15A breaker (no snakes in the room, in case you're wondering). The only things I can think of are:

1) startup current exceeds the capability of the relay, which should be 12.5A since the Herpstat is rated to 1500W.
2) the Herpstat relay has a much lower capability than advertised.
