Heating or cooling module

The heating or cooling module controls the heating or cooling in maximum four zones or rooms. Each zone or room should be equipped with a Niko Home Control thermostat. The module has four outputs to control zone valves (e.g. zone valves at 230 Vac or 24 Vdc) or circulation pumps in four zones or rooms, and one output to set the heating or cooling system to the day or night mode (depending on the heating or cooling request of one of the zones or rooms) Most boilers or cooling units are fitted with an input contact (e.g. a telephone or boiler contact) for this purpose. The module is provided with five indication LEDs and one status LED. Bistable relays ensure low energy consumption. You contact the HVAC installer to have the heating or cooling system fitted with zone valves (e.g. zone valves at 230 Vac or 24 Vdc on the heating collector or radiator) or tunable circulation pumps and to verify the contact of the heating or cooling unit to which the system should be connected.

Specification description

Heating or cooling module for Niko Home Control.

  • Function: The heating or cooling module controls the heating or cooling in four zones or rooms.

The module has four outputs to operate control valves (e.g. electronic valves at 230 V AC or 24 V DC), pumps, electric heating units or individual cooling units (e.g. air-conditioning units or fan convectors) in four different zones or rooms. This allows you to apply different heating or cooling settings to each one of the four zones or rooms fitted with a Niko Home Control thermostat. The module uses one output to control the heating or cooling system. When the module receives a heating or cooling request from the Niko Home Control thermostat in one of the zones or rooms, the H/C contact of all the modules will be closed which then activates the central boiler or cooling unit. The most centrally located boilers or cooling units are fitted with an input contact (e.g. a telephone or boiler contact) for this purpose. If not, a special regulation module will be added to the central boiler or cooling unit. In installations with a hot water reservoir, the circulation pump will be activated. To avoid conflict in the installation, the module takes into account the opening and closing times of the electronic valves as well as the lag time of the heating or cooling system .

When the module is functioning properly, the STATUS LED will light up in TEST mode only. If one or several errors occur, the LED will blink to indicate the error code of the error with the highest priority.

Connected controller for Niko Home Control II

The connected controller is the central module of every Niko Home Control installation for bus wiring. This module contains firmware that can only be programmed with the Niko Home Control programming software 2.1.1 or higher. It covers all basic functions on which a Niko Home Control installation is built. The basic functions include: • The intelligence directing the logic to the installation. Through the configuration software, the logic is saved locally on the controller. • The power supply module providing an input voltage of 26 V to the bus, the cabinet modules and the controls. Depending on the size of the installation, separate power supply modules can be added. • The connection to Niko Home Control IP devices such as touchscreens and external video units. A built-in router allows the user to connect up to 3 devices directly to the controller. With an extra switch, this number can be increased. • The connection to the internet. This enables the user to control the installation both indoors and outdoors (via mobile networks such as 3G, 4G, GPRS or Wi-Fi hotspot) using mobile devices (smartphones and tablets with iOS or Android). The module has a TEST button to verify the proper functioning and status of all other modules. The SERVICE button allows you to perform waiting Niko upgrades. Each installation must consist of one connected controller. After registration on https://mynikohomecontrol.niko.eu, your installation is connected, enabling control through the app via your smartphone and tablet, and you can enjoy the Niko services for upgrade or diagnosis of the installation.

Digital black, connected customisable control screen for Niko Home Control, 24 V

Digital black is a completely customisable control screen for Niko Home Control with an extremely user-friendly interface featuring clear symbols. The screen is automatically activated when your hand comes near. That way, you can switch or dim your lights, set moods, set ventilation modes, adjust blinds and sunblinds to the desired position, in one operation. In short, all possible Niko Home Control control types are available. As this Digital black 24V variant is equipped with a temperature sensor and algorithm, it can be programmed as a zone-thermostat when linked to a Niko Home Control heating cooling module (ref. 550-00150) or switching module (ref. 550-00103 or 550-00106) programmed for electrical heating. Do you have extra thermostats (550-1305x) or an active connection with one of our heating partners? Then you can easily set the temperature with the Digital black. When the Digital black is used as a thermostat, you define the set points and week programs in the Niko Home app. With the Niko Home app not only can you choose which controls are displayed or where they are displayed on the screen, but also the way you navigate through your control screens. You can download this app for free in the app store or play store. The screen can be easily mounted in any standard flush-mounting box using the familiar claw or screw fixing and is powered by a separate 24V DC supply (e.g. 340-00050). The screen communicates via your wireless home network with the rest of your Niko Home Control system. You need an active internet connection to activate the screen. This internet connection ensures that your screen and Niko Home Control installation are always up-to-date, and have the most recent functionalities.

Power supply

The power supply, in combination with the connected controller, provides an extra input voltage of 26 V to the bus, modules and controls. An extra power supply is only necessary in installations for which the power of the built-in power supply of the connected controller is insufficient. Up to 2 extra power supplies can be connected to installations with a connected controller. The MASTER button is not used, as the built-in power supply of the connected controller is always the master. For more information on the required number of power supplies, you can consult the installation manual.
