1. INTRODUCTION
Heatit DIN Smart Thermostat is an electronic thermostat
designed for electrical heatingand cooling. The thermostat can
be controlled via Z-Wave
®
controlled by Wi-Fi using the MyHeatit app, or via Modbus 485
and the buttons on the front of the thermostat. The thermostat
has a user friendly interface.
The Heatit DIN Smart Thermostat is a versatile solution for
both residential and industrial use. It functions as a standard
floor heating thermostat, offering simple temperature control
with three modes: Heat, Cool, and Eco. Additionally, it features
a specially designed industrial function (INDU) that allows
it to handle setpoints ranging from -30°C to 85°C, making
it ideal for demanding industrial applications. It can also
be used as a plus/minus snow melting thermostat (PLUS),
adjusting temperatures for efficient snow and ice melting on
outdoor areas, driveways, or stairs. With the Heatit DIN Smart
Thermostat, you get precise temperature control for a wide
range of purposes.
The thermostat clicks easily on a standard DIN rail and can
be installed in the main switchboard. The thermostat has
connection for two external temperature sensors.
While used on Wi-Fi, the thermostat can communicate over
a local API, where the user can make integration with a local
gateway, server, controller that offers such a service, without
needing connecting it to the cloud. The device also supports
Amazon Alexa and Google Home (Amazon Alexa and Google
Home are pending).
To see more information regarding the functionality for the
Wi-Fi version, see the Wi-Fi manual of the product.
Heatit DIN Smart Thermostat has active power metering
and it gives you real time information about your power
consumption. It also allows you to set the power metering
value manually in case of connection with a contactor.
The device has implemented ZeroX™ technology. This
technology makes sure the relay switches at 0V when turning
on and off. With this technology the thermostat will have a
much longer lifetime.
Heatit DIN Smart Thermostat has been developed for central
controlling systems and all the features are easily accessible
over MODBUS 485.
The thermostat can withstand a load of max 16A/3600W at
230VAC. We recommend a contactor for loads above 13A.
