Thermostat PWM - ZMNHLA2

Z-Wave Plus flush-mounted PWM Thermostat from Qubino - ZMNHLA2 with Power Metering feature.

Discrete Z-Wave PWM thermostat to control floor heating or radiator. This micro module makes it possible to manage the temperature of your heating floor using the PWM (Pulse Width Modulation) technology allowing an optimal regulation of the temperature and a constant temperature. You will therefore save energy thanks to this mode of operation. There are also several modifiable parameters such as P, I and D, the duration of a PWM cycle, maximum and minimum values, frost protection mode (to prevent freezing of water in pipes) or other options for The PWM system setting.

• Communicates via Z-Wave Plus RF (868,42 MHz)

• Output circuit power of DC output (resistive load) = 1 X 21W (24V DC)
• Switching: MOSFET
• Power measurement accuracy: ±2W
• Power consumption: 0,7W
• Temperature control via connected DS18B20 sensor (included)
• Temperature Detecting Range: from -50°C to +125°C
• Temperature Accuracy: ±0,1°C

IMPORTANT! Must only be installed by an authorized electrical installer. Private individuals who want to carry out work on the electrical system themselves must first study information from dsb (Directorate for Civil Protection and Emergency Planning) - Electrical work: You can do this yourself

Attention! The floor sensor should be laid in an installation pipe that is cast into the floor. This pipe should be laid as high as possible in the cast (floor underside). The sensor cable can be extended. The sensor cable should not be laid in parallel with cables carrying large currents, as this may induce unwanted signals.

Note: Wooden floor with electric underfloor heating requires that a floor sensor is connected. Thus, floor temperature is limited to 27°C.
