i've never done any test on this, might have to take amp draws and find out. normally a control device (stat) does not take full load unless something is needing full load(heat source) ie you can have a unit on a 30 amp breaker and it only needs and draws 19 amps to run. i might have to play around with some flex and see! at first thought if the flex isn't going full blast, i see no reason why a helix would use full load?
