    Instruction Sheet

    R331 series digital thermostat is suitable for temperature control of Fengji Panying, electric valve, electric valve, electric Fengkou and Yipin equipment. The large-screen LCD display is used to detect the indoor temperature through the NTC (negative temperature coefficient) temperature sensor inside the thermostat, and compare it with the temperature set by the user in real time. Automatically adjust the air intake volume and turn on or turn off the air-conditioning and heating system. The pipeline electric valve achieves the purpose of maintaining the indoor temperature. It is recommended to be used in conjunction with the V2016 series, V4016 series, V6016 series, and V8016 series electric valves.
