<p dir="ltr">Great, what's the future of the current split system? </p>
<p dir="ltr">I mean, how upgradeable it will be? </p>
<p dir="ltr">What is the cost of the board and which Conrad TRV are we talking about? </p>
<p dir="ltr">Also how exactly do you 'interact' with the current split system? Apps? </p>
<p dir="ltr">Thank you. </p>

<br>
OpenTRV is about zoned occupancy-sensitive space heating that can give up to 50% energy savings if fully interacted with, and ~10% if you ignore it!<br>
<br>
The current engineering ‘split’ solution uses a hand-held controller third-party valve driver; our all-in-one solution going through production engineering right now has our own mechanics also.<br>
<br>
In either case these can operate stand-alone, or also control the boiler to maximise savings.<br>
<br>
If you want to use the engineering ‘split’ solution based on the REV2 board then I can sell you one of those at cost and point you to the Conrad Web site for the matching valve controller.<br>
<br>
There are other possibilities, but not instantly available.<br>
