THE ISSUE WITH MULTI-BRAND HVAC INTEGRATION
Integrating a Daikin, Mitsubishi or any other make of VRF to Building Management systems seems like a no brainer. Many of the VRF HVAC manufacturers provide an open protocol leaning on a third party gateway, and most challenges arise just when you need support. Daikin along with all other makes offers the same integration method, applying a gateway. Sounds easy right!
Until when your site has multiple HVAC brands installed. How do you overcome the problem if you have to apply integration to all the units, regardless of the brand? The only solution (until now) is you need multiple gateways for every brand and to set up the logics for all units, grouped by brands.
Searching for the brand designed solutions will lead you to the ultimate challenge - working with an unfamiliar protocol that is rarely designed to help a BMS savvy professional with no time on his hands.
THE SOLUTION FOR ALL VRF HVAC INTEGRATION PROJECTS
Our tech team recognised this issue and developed a solution to solve this specific problem. With simplicity and cost-efficacy in mind, a small device was developed - A Universal Gateway.
The device allows all Building Management Integrators to connect the VRV and VRF HVAC with any standard building control system, using open built-in protocols.
This saves time searching for a third-party device and setting up a configuration using unfamiliar protocols and gateways. The integration process of all connected HVC brands is the same regardless of the connected HVACs. EnviroLogik will unify the integration process of all connected systems, regardless of the brand. Moreover, instead of repeating the setup of the BMS to multiple gateways, a single set up for our gateway will apply to all connected systems.
HOW DOES THE SOLUTION WORK?
The most important capability of the device is its ability to convert the native protocols of all VRF/VRV manufacturers into an open protocol (BACnet IP, BACnet MSTP, Modbus TCP, Modbus RTU, KNX). You will only need one device with multi-brand support for all systems containing up to 256 indoor units. (Note, some of the manufacturers limit the number of indoor units per communication line, so our EnviroMaster VRF interface keeps this limitation.)
The conversion applies full bi-directional control and keeps all functionality that was designed within the HVAC: modes, setpoint, temperatures, errors, etc. You can apply the same rules you define once you set them up.
EnviroMaster is your fallback as a local control device. Using the touchscreen, you have full control over every single indoor unit connected.
With basic to no set-up in the field, when connecting the VRV/VRF bus, EnviroMaster will automatically recognize all connected units, display them in seconds, and allow full control of each indoor unit by its unique address.
When you get to the desired commissioning process, you can check the system function using EnviroMaster and our Control app. The device comes with an application suite and the Control App displays live all unit status. Thankfully, the days when you had to run up to the 20th floor when the elevators weren’t working are now over.
Support of DHCP and static IP, changeable from the touchscreen.
Support of split/multi-split units (by multiple brands), with the additional EnviroPlug device connected to the indoor units in the same project with VRV/VRF installation.
EnviroLogik remote support for each of the EnviroMasters connected to the internet
