Overview

Split infrared controlled HVAC systems are quite common in Australia and New Zealand. The issue with these systems is that control is only one way, without any feedback what so ever. Furthermore each IR string contains code information about the mode, fan speed and set point within in. Given this you must learn every single combination of IR code to get full integration into your home automation system.

The Chowmain Generic IR Thermostat driver enables us to integrate infrared controlled HVAC systems into the Control4 system with feedback from a dry contact (to sense if it is on/off) and temperature input from the Control4 Thermostat, Axxess Motion Sensors, Card Access Contact Sensor or Relays.

The driver also provides the ability to preset and schedule.  This provides a total smart solution for what would be a one way system. Note this driver is only compatible with HVAC systems that utilize Celsius.


The two options we recommend for installation are as follows:

  • Option A: 'Retrofit' via a Card Access Zigbee 2 IR device / Matterlink MultiX gateway
  • Option B: 'New Construction' via hard wired connection from a Control4 Controller or IO Extender.

In both cases installation is recommended on the interior of the heat pump chassis to ensure a clean look. However if this voids the manufactures warranty a tidy exterior installation can easily be done.

FAQ

Can you give us some examples of how we could use this driver?

This driver is extremely useful for countries where IR based HVAC solutions are common. By combining it with 3rd party temperature inputs you get a fully integration IR HVAC solution within Control4.

Are there any other cool things we can do with this driver?

  • This driver supports an optional contact input. This is useful for when the consumer utilises the existing IR remote control for feedback. It will set the mode to off when the unit shutter closes and to auto at the last setpoint when the unit shutter opens.
  • This driver has an inbuilt webserver for setup and control. If the client is on their PC they can control their HVAC system by just visiting the URL specified in the properties page of the driver.

What hardware will this work on?

This will work on all IR based HVAC systems. Note that a 3rd party IR learner is required to learn the codes. Temperature input is compatible with the Control4 Thermostat, Axxess Motion Sensor, Card Access Contact and Card Access Relay.

Where do i find IR backup files for existing systems? 

You can download IR backup files from our website.

Why do you only support OS 2.6 and above?

OS 2.6 offers a superior security encryption algorithm and a new and improved driver format. We have decided to only utilise this new format to ensure that the integrity of this driver is not compromised and that we can provide the best dealer/user experience available.

I am using an EA Controller and have issues sending IR to my HVAC system

Control4 have advised us of a bug that effects control over IR based HVAC systems on EA controllers. They have created a patch to fix this issue for OS 2.8.2. This patch will be included in future versions of OS automatically. Please see knowledgebase article below if this effects you.
