The UCM/Pi is a host adapter, linking a Raspberry Pi Industrial Compute Module 3/3+ (CM3) or compatible single board computer to the Cytech Comfort range of products. Benefiting from the tight integration with the Comfort system, the CM3 has a direct serial interface to the UCM and includes an optional hardware watchdog. The UCM may be powered by the Comfort system where it benefits from the battery backed up power supply.
The installer or user has the option of using software developed by alphaWerk which includes MQTT, Node-Red, openHAB and Home Assistant support or, with the technical documentation and operating system configuration provided, they may develop their own.
Requirements
- A Raspberry Pi Compute Module 3 or Raspberry Pi Compute Module 3+ is required. Onboard eMMC flash is required and 8GB+ is recommended for future upgrades of the Raspberry Pi OS and alphaWerk UHAI software. The Raspberry Pi Compute Module 1 and Lite versions of the Raspberry Pi Compute Module 3/3+ are not compatible with the UCM/Pi.
- Ethernet connection at the Comfort panel is required.
- Comfort II Ultra main panel with 7.x firmware and a working backup battery is required.
Note: The Raspberry Pi Compute Module is not included but required. All software related to the UCM/Pi and installation is supported by alphaWerk directly.
Power Supply | 12V |
Current Required | Idle 300mA, peak 600mA |
The 12V backup battery on Comfort must be connected to provide intermittent high current for UCM/Pi. An external 12V power supply may be required if Comfort power supply is overloaded. This may cause UCM/Pi to reset.
