Most HVAC installations in the United States are easy as most thermostats utilise a universal standard and as such can be replaced easily by a 3rd party thermostat such as Control4’s thermostat.
Unfortunately alot of HVAC manufacturers do not utilise this standard and have proprietary closed communications that are specific to that HVAC manufacturer. This makes it extremely cumbersome for Control4 dealers to source a reliable HVAC product and in many countries Control4 dealers do not even bother with HVAC integration because it is just too hard.
Luckily Intesis have released their range of IntesisBox wifi gateways. The IntesisBox allows you to easily integrate HVAC systems into Control4 by retrofitting the IntesisBox gateway into the existing indoor unit. Intesis offer two gateway types. Specific IntesisBox’s are developed to communicate with the HVAC manufacturer’s proprietary communications protocol allowing for true real time bidirectional communication with the system. Universal IntesisBox’s are developed to offer compatibility with thousands of HVAC models through infra red and offer room temperature feedback via a sensor in the IntesisBox. The universal model also provides feedback when the customer uses the original IR remote to control the HVAC system.
Chowmain’s IntesisBox driver for Control4 will work with all models of IntesisBox and will provide full two way control/feedback.
- Automatic discovery of Intesisbox based on unit MAC address.
- Self healing - if IP address changes the driver will automatically rediscover the unit.
- Auto configuration of available of HVAC Modes from IntesisBox.
- Auto configuration of available of Fan Speeds from IntesisBox.
- Auto configuration of set point limits (minimum and maximum).
- Auto configuration of available vane positions.
- Temperature Feedback.
- Setpoint Control.
- Up/Down/Left/Right Vane position control
- Built in Scheduling.
- Built in Presets.
- Relay based zone bindings for motorised dampers
- HVAC System Error detection and feedback (only on non universal IntesisBox’s).
- Support for multiple AC units (this will work on future IntesisBox hardware – Current version only supports single indoor units).
- Can get feedback when the customer uses the original IR remote for the Universal IntesisBox model.
Why is this product exciting?
In Australia and New Zealand (and other countries) HVAC integration has been hard because HVAC companies do not utilise the honeywell based wiring that most smart thermostats like Nest, Control4 and Honeywell use. Split Systems have been extremely hard as traditionally they only offer IR or RF based remote controls. In the past we have integrated these systems by learning every combination of IR code however this is extremely time consuming. Also integration for ducted systems and VRF systems were hard because manufacturers have their own propriatary bus.
Now with the IntesisBox installers can now easily integrate HVAC systems into Control4. The IntesisBox is affordable unlike other solutions so the cost of integration per zone is extremely low. On top of that it communicates via wifi so dealers can now revisit old customers with compatible HVAC systems to upgrade their home automation system and integrate their HVAC systems without additional wiring.
This really changes the HVAC game.
What HVAC systems can i use this driver with?
IntesisBox is compatible with a range of HVAC systems. Please see the Intesis website to check if the HVAC system you want to integrate has a specific IntesisBox or is compatible with the universal IntesisBox. Their website will have the most upto date information about supported models. If you are unsure if you HVAC system is supported please contact Intesis support (email@example.com) and they will advise if you HVAC system is supported and what model IntesisBox you need to purchase

Intesis sells the IntesisBox in over 90 countries. They mainly sell direct. The product has regulatory compliance for Europe, US, Canada and Australia. If you have any sales enquiries please contact Intesis Sales directly via their website or contact them via firstname.lastname@example.org.
Why do you only support OS 2.7 and above?
This driver requires functionality that is only available in OS 2.7. As such this driver will not work in earlier versions of Control4 OS.
Do you offer showroom discounts?
We offer dealers a free showroom licence for demonstration and educational purposes. See link below for T&C's and signup procedure.
