Heatit ZM thermostat 16A

The Heatit ZM Single Thermostat 16A Z-Wave is a flush-mounted thermostat designed for installation in standard wall boxes, enabling wireless control of electric heating systems via Z-Wave network connection. This device features a single-pole 16A relay and requires the connection of an external wired temperature sensor, which is included in the package. With a maximum load capacity of 16A at 230V AC, it supports resistive loads up to 3600W and inductive loads up to 16VA. The thermostat integrates a power measurement function that provides real-time power consumption data for users. It operates with the Z-Wave protocol at 868.4 MHz (EU) using Z-Wave 700 chip technology with S0, S2-unauthenticated class, and S2-authenticated class encryption via AES-128. The device ensures operational reliability within an ambient temperature range of 5°C to 40°C and a storage temperature tolerance from -50°C to specified limits, with environmental humidity compatibility between 10-85% relative humidity without condensation. The physical dimensions are 45 mm in width, 25 mm in length, and 46 mm in height, with a product weight of 41 g. Installation requires a wall box with a minimum diameter of 60 mm and a depth of 60 mm, capable of accommodating connection wires up to 2.5 mm² in cross-section. The thermostat has an IP20 protection rating and complies with several international standards, including CE declaration of conformity, RoHS 2002/95/EC, WEEE 2002/96/EC, as well as various EN and ETSI specifications. The wireless communication range extends up to a maximum of 40 meters under optimal conditions. The included temperature sensor serves as a reference for thermostat operation and does not function as a temperature limiting device.
