Heatmiser + CoolMaster Combo driver for Crestron Home
Please Login / Register to view pricing.
Crestron Home driver for CoolAutomation AC interfaces with Heatmiser UF heating systems, providing a complete heating and cooling solution in a single driver.
Overview
This Crestron Home driver has been designed to provide two-way control of CoolAutomation air conditioning interfaces and Heatmiser underfloor heating systems, offering a complete heating and cooling solution within a single driver.
This means there is no longer a need for multiple Crestron Home thermostats in a single room, nor complex, clunky programming to make everything work intuitively. One thermostat driver handles both heating and cooling, automatically managing the “deadband” to ensure the systems do not compete with each other.
All integrations are managed through a very easy-to-use and intuitive web application. This driver supports scheduling and, with the use of Profiles—a powerful feature for configuring multiple unique schedules for a single thermostat driver—you can easily switch between them at any time from your Crestron Home web scheduler page. This makes it simple to switch between profiles to suit different times of the year.

How do I configure the system
Once you’ve added the driver on to Crestron Home. Click on the settings button on the driver and head over to the installer settings section. Here you will be able to access the Web applications for the ‘Web Configuration’ and ‘Schedule’.
I cannot discover any zones after adding a Gateway
- If no devices are discovered, follow these steps:
- Ensure that you have entered the correct IP address and port number for the Heatmiser or CoolMasterNet device. Make sure you have selected the correct type. Also, ensure that the Connection Status shows as Online. This status will report any connection issues.
- Click the Refresh button in the Connection Status section to rediscover the thermostats.
- Ensure Legacy API is enabled in the HeatmiserNeo App under Settings > API > Enable Legacy API.
If you still can’t discover the expected zones, feel free to contact us at support.janustechnology.co.uk including the driver version and the variant you are using. We’ll be happy to help.
How do I set up schedules?
Access the Scheduler web application from the installer settings of the driver. Here, you will be able to access all zone controllers that have been created. Schedules can be set for each individual zone controller and can be copied across days of the week.
How do Profiles work?
Profiles is a new concept introduced by this driver that enhances the functionality of the thermostat proxy.
When you create a schedule, it applies year-round. While this simplifies schedule creation, it doesn’t account for seasonal changes—you may want a completely different schedule for summer than for winter.
Profiles solve this by allowing you to store up to 8 unique schedules within the thermostat driver. You can switch between these schedules at any time using the Web Scheduler. There are no limitations on how you configure your profiles.
Simply add new profiles before setting up any schedules.
I have multiple 2-pipe Coolmaster systems
Add the 2-pipe systems under the systems section in the web configuration app. Select the AC devices which are a part of this system, and choose the Master Device. The Master Device is the AC unit responsible for the changeover between Summer and Winter.
Deadbands for Heat and Auto Modes
Auto Mode:
- This is only use when the HVAC mode is set to ’Auto’.
- This Deadband is used to describe the ‘acceptable temperature’ region around the current setpoint where there is no HVAC demand, and the room is neither heating nor cooling. This helps to prevent oscillation.
- For example – if you set this property to 2C, for a setpoint of 21C, the room will start heating at 20C and start cooling at 23C.
Heat mode:
- This is only use when the HVAC mode is set to ’Heat’.
