Heatmiser RS485

[palmlodge]

I\'ve got a Heatmiser control system for the heating system - multi zone, touchpad, etc

This is a vote for a new UCM that can talk into Heatmiser - and Comfort can then totally control the heating system. Cytech have the protocol documentation.

 

For any Comfort users who have a normal central heating system (or an alternate heating control thats standalone) - Heatmiser do a direct replacement for about £40 (US$80) - this could then be connecte to Comfort.

Aye, - I\'d buy that for a dollar....

consider this a vote in favour!

I would vote for it

Assuming the UCM would work with Comfort 1 then I would go for that!

Another vote here, I have Heatmiser in all zones and a Comfort system.

A good call for this I think.

I\'d have one of those if they existed!

We likewise have a number of PRT-N stats, and the touchscreen - woud be great if comfort could control it all based on time, other temps (solar hot water, external and domestic hot water would be great) and occupation.

Some good examples of control might be :

 

1. Allow Comfort to control times and temp. setpoints

2. If Away Mode, dont put the heating on

3. If vacation mode, dont put the hot water on, nor the heating

4. Put controls on the Comfort touchscreen ?

5. Any others ?

 

Heatmiser PRT-ENs just tell relays to go on or off - they dont switch the load directly themselves. They should pretty much work with any type of heating system.

They are about the same price as a standard off the shelf unit, and gives the advantage of \'networking\' - you can easily swap out your existing sensor for the high load version (not the EN\'s) - and still have networking.

This sounds very useful.

We\'re going to be extending the house this year, and intend to fit Comfort in the process.

We have Smartfit already so will fit the UCM to control that (if we end up keeping the smartfit controller), but we\'ll need additional zoned control for the new rooms. Smartfit doesn\'t support multiple zones, but the heatmiser range looks like it could fit the bill.

We have also looked at this briefly and the cost/performance of heatmiser is attractive.

As I understand it all zone control is local to the heatmister stat, that is temp readings, timers etc. but these are all blurted over a RS485 bus. And can be overridden remotely aka thier touch panel.

So Comfort should be able to report/adjust zone temps & provide timer control of different zones readily.

Another intresting product although closed is Honeywell\'s CMZone. If this could be hacked it offers retrofit options for those with radiators. I know Hometronic is the baby here but it starts to add the expense & duplicates Comfort in many ways.

Hi Guys

Can anyone offer me advice on how to get my computer communicating with my heatmiser thermostate, I have bought a RS485 convertor but have no idea after that.

Any help would be appreciated.

Thanks
