any pointers

I have a intermediate level of programming and need a few pointers.

I have a project that has underfloor hydronic heating installed. The system is working ok but I need a few pointers to make it more usefull.

I have single room thermostats measuring the room temp & controlling the actuators. I have written a logic code to start the boiler when it flow starts and
turns off when the actuators shut down.

What I havent worked out yet is how to adjust the set point temp on the touch screen. Currently the room temps are set by toolkit. I have buttons & measurement indicators on the touchscreen so I know what the temp is & if the load is on.

I would like some tips on how to program a nudge up/down with a set point to raise or lower the desired temp.

Regards

There is quite a lot more information we will need before we can provide any guidance.

To clarify this - you have single zone C-Bus thermostats at the moment, and they are controlling the temperature correctly?

Is each room on a separate Zone Group?

So the boiler starts when any one of the rooms requires some heat and it switches off when no rooms require any heat?

See the help file topic "HVAC App In-Built System IO" and the "thermostat" template.

The "thermostat" template has buttons to nudge the set-level up and down. Have a look at how it is done on the template.
