Heatmiser UCM

[ident]

The UCM/Heatmiser allows the integration of Heatmiser thermostats, both RS485 and wifi types, with the Comfort integrated Intruder Alarm/Home Automation System.

Update/Warning
Note that only Heatmiser products supporting the V3 protocol are supported by the Heatmiser UCM. The wifi thermostats have been discontinued and are replaced by models which are not compatible
Please check which heatmiser products you would like to work with before deciding on the UCM/Heatmiser


Heatmiser Thermostat shown above


The UCM/Heatmiser has the following functions;

1. allows control and  temperature monitoring of Heatmiser thermostats from keypads, telephone, iPad/iPhone/Android app, SMS (with UCM/GSM), or software.
   
2. allows control of Heatmiser thermostats by Time Programs.
3. allows setting of the alarm to Away, Night, Day, Vacation and Security Off to change heating and cooling setpoints in Heatmiser.

The UCM/Heatmiser comes without an interface, and an interface submodule AUX485 for RS485, or ETH03 for wifi heatmiser products must be addded according to the type of heatmiser to be supported


The UCM/Heatmiser with Isolated Rs485 interface is shown below.






The UCM/Heatmiser with Eth03 interface is shown below




The UCM/Heatmiser manual can be downloaded from https://www.cytech.biz/ucmheatmiser_manual.html

System Requirements

1. Comfort Firmware 7.042 and above
2. UCM for programmming  7.038 and above
3. UCM/Heatmiser 7.038 and above with ETH03 or Rs495 Interface
4. Comfigurator 3.7.8 and above
   

[ident]

UCM/Heatmiser with the ETH03 submodule is required for Heatmiser wifi modules
You do not need the Heatmiser Netmonitor

Connect the Ethernet port MJ101 on the ETH03 to the Local Area Network (LAN) by means of a hub or switch using a parallel CAT 5 cable.  The WiFi Heatmisers should be connected to the same network

Comfort Server Manager (CSManager) software is used to configure ETH03 to have Heatmiser related settings. The software is included in Comfigurator 3.7.8 and above or can be downloaded from Cytech website at https://www.cytech.biz/comfort_server_manager.html
In Comfigurator 3.7.8, go to Options > Settings > UCM Connections and select Network (Local). Click on the link for Comfort Server Manager.



When the ETH03 is connected in the same physical network then Comfort Server Manager will automatically discover it.

Ensure the Version has the word HM (for Heatmiser) i.e. Eth3HM-v1.04 for the current release. The ETH03 firmware for Heatmiser can be downloaded from  https://www.cytech.biz/eth03_firmware.html   Download ETH03-heatmiser.zip and unzip to a hex file.

To upgrade to change the ETH03 firmware to Heatmiser, select the ETH03 IP address and click on the \'Upgrade\' button on the bottom right. Select the downloaded ETH03-heatmiser.hex file

\'Clear List\' button clears the display on the Comfort Server Manager screen.
The \'Discover Devices\' button is used to discover any ETH03 module that is connected to the same network e.g. after \'Clear List\'

\'Reboot\' button reinitialises the ETH03 module.
By default the ETH03 is set as DHCP enabled. Uncheck the DHCP checkbox and enter the new IP and Gateway fields to assign a fixed IP address for the ETH03 module. Press the \'Submit\' button to confirm.

Routing Mode: Client (mode in use for Heatmiser)
Port:                1001 (default)
Target IP:        The IP address of any one of WiFi Heatmiser module
Target Port:      8068 (port in use in WiFi Heatmiser, this is fixed)
Timeout:          Not used in UCM/Heatmiser

Principle of Operation

The UCM/Heatmiser supports integration for up to 32 thermostats, 32 humidity/temperature sensors, and an outside temperature sensor (for RS485). Up to 8 wifi thermostats can be supported by UCM/Heatmiser with ETH03.
Comfort can be configured to control and monitor certain parameters of Heatmiser thermostats by first mapping them to Comfort\'s Register (Counter, Flag or Sensor).



Temperature is mapped to Comfort Sensors (0 to 31 in Ultra). Sensor values can be assigned as status feedback for Control Menu so that they can be heard on the keypad or phone or seen via the Comfort iPad/iPhone/Android Apps. A Comfort  sensor can be mapped to only 1 Heatmiser temperature sensor to avoid conflict of values. Changing the Comfort sensor value will not have any effect on Heatmiser temperature reading.

Temperature Setpoints are mapped to Comfort Counters (0 to 254 in Ultra). Counters can be assigned as status feedback for Control Menu so that they can be heard on the keypad or phone or seen via the Comfort iPad/iPhone/Android Apps. A counter can be mapped to only 1 Heatmiser setpoint to avoid any conflict of values. Changing the value of the mapped counter will also change the setpoint on the mapped Heatmiser

Thermostat On/Off states are mapped to Comfort Flags (1 to 255).  Flags can be assigned as status feedback for Control Menu so that they can be heard on the keypad or phone or seen via the Comfort iPad/iPhone/Android Apps. A  flag can be mapped to only 1 Heatmiser  state to avoid any conflict of values. Changing the value of the Comfort Flag will also change the  state on the mapped Heatmiser State.

The Wifi Heatmiser thermostats have been obsoleted, replaced by \"Smartstat\" wifi thermostats. Please note that these are NOT compatible with UCM/Heatmiser. These products cannot be controlled

Does anyone have any experience with interfacing wifi thermostats with UCM/Heatmiser?

[palmlodge]

Is the UCM/Heatmiser (RS485) compatible with the Heatmiser v2 protocol - the PRT-EN units?

[slychiu]

I know about the V3 protocol i compatible with UCM/heatmiser
Not suree what is the diference with V2.

Hi

Could you tell me a little more about what this ucm lets you do with heatmeiser - ie can you do the same as if you were using their programmable thermostats?

I have a heatmeiser system with 4 stats and wiring centre.

For example, can I control all 4 via comfort? If so, is it done through the control menu? Ie whether using phone, app or keypad, you go to control menu? Can you for example do temperature up and down? Can you do hot water boost?

Trying to work out if it’s better just to get their control centre so I can control everything from one point.

Thanks

[slychiu]

You can control the heatmiser by keypad using the control menu, by comfort app, byu time program etc

However take note of the warning below;

They changed their protocol with the newer products so it is diffciult for 3rd party  systems to keep up.

Has anyone tried the heatmiser v2 touchscreen thermostats ?
I see that they have a modbus interface but the manual doesn\'t say what can be commanded or queried.

If I were to pair this with a modbus UCM could i control it from comfort ?
And if so, how might I control it using the comfort app ?

Regards
John.Ps sorry I thought I had created a new thread but now see it has gone on this pinned thread.

[slychiu]

If they do have a modbus interface then you should be able to control by UCM/Miodbus and by Comfort apps

You would have to know what Modbus registers they use
