Due to its wide voltage range the hygrotherm can be utilised anywhere in the world.The LED integrated in the adjustment knob on the active controller is lit when the connected device is in operation.Switching difference - temperature 2K (%u00b11K tolerance) at +25%u00b0C (+77%u00b0F), 50% RHSwitching difference - humidity 4% RH (%u00b11% tolerance) at +25%u00b0C (+77%u00b0F), 50% RH Response time - humidity approx. 5 sec.Contact type change-over contact (relay)Contact resistance < 10m%u00d9Service life VDE: NO/NC > 15,000 cycles UL: NO/NC > 30,000 cyclesMax. switching capacity 240VAC, 10 (1.6) A 60VDC, 0.6A%u00b9 Max. inrush current AC 30A for 10 sec.
