I agree it's unlikely, but it doesn't necessarily mean it isn't so. My interpretation of the 411 wiring diagram on the BODA site is as stated. See attached and let me know if I have got it wrong.
It looks as though the thermostat switched relay is fed via a fuse from the battery while the manually switched relay is fed by an in line fuse powered through the ignition switch.
