Overall Power Consumption: Quiescent current: ≤10MA, operating current ≤65MA
Indicator Light Direction: Flash shows start-up delay of refrigeration or heating, keep lighting shows the relay has closed
Nixie Tube: LL state shows open for sensor; please connect the sensor base on instruction,
HH state shows exceed measurement range, temperature controller would peremptory turn off the relay,
--- state shows high temperature alarm
Connect the power supply and equipment to supply power to the controller. At this time, it is displayed as measuring temperature. Press SET once, the display temperature will flash, press +- to set the desired temperature (press +- to quickly raise and lower) After finishing, press SET to confirm the return. At this time, the controller automatically performs relay on/off according to the setting! The output of the thermostat is a 10A relay, which satisfies various high-power loads, and connects the control circuit to supply power to the thermostat. At this time, the display shows the ambient temperature.
Indicator light: Blinking indicates cooling or heating start delay, always on indicates that the relay is closed
Digital tube: Display LL is the sensor open circuit, please follow the instructions to connect the sensor; display HH is out of the measurement range, the thermostat will force the relay to be disconnected; display --- for high temperature alarm
Package included:
1 PCS x DC 12V Relay Switch Control Digital -20 to100° Temperature Display Module Sensor
