Thermostat - HE-HT01

Z-Wave Plus V2 Controlled Thermostat - HE-HT01 from Heltun.

The HELTUN HE-HT01 Advanced Programmable Thermostat for Heating systems can be flush mounted over standard electrical junction boxes. It is designed to maintain a constant room temperature by providing sensors for both ambient and radiant floor heating systems. It is recommended for control of electric heating systems (radiator, convection, electric fireplace), boilers, or electric underfloor heating. Heating elements are directly controlled by a single-pole switch. The maximum load for the HE-HT01 thermostat is 16 Amps (4000W @ 250VAC) which must be connected through a circuit breaker.
The HE-HT01 has an LCD screen, six sensitive capacitive touch control buttons, and two temperature sensors (for ambient air temperature and an external NTC floor sensor). It is also equipped with built-in sensors for humidity, illumination, and energy consumption.
The HE-HT01 integrates a Z-Wave 700 platform module allowing it to be used with Z-Wave home automation systems. The HE-HT01 supports Z-Wave ‘S0’ and ‘S2’ security protocols, SmartStart technology, and can be connected (“associated”) to ten other Z-Wave devices, such as relays, switchers, etc. You can select one of six operation modes either manually, or by using a Z-Wave controller/gateway. As a safety measure, the HE-HT01 protects radiant floor systems from overheating by automatically switching off if the temperature reaches 40°C.
The display has a user-friendly interface, showing: ambient air temperature, floor temperature, user set point, humidity level, current operating mode, time, day of the week, and status of the Z-Wave network and relay. Display brightness adjusts to ambient light conditions automatically making it always easy to read.

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 plastic 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 with a high-current cable. 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.
