Re: Underfloor heating and HA control?

[Lehane Kellett <lehane@xxxxxxxxxxxxxxxxxxx>]

Whilst we have UFH in concrete, it should be the same.

I embedded some Dallas sensors in the screed to give the floor readings
and have room sensors in addition. These are all linked to TOM 10/xAP
and use scripts in xAP Floorplan which also display the temperatures
around the house on the plans.

As a backup, there is a single Heatmiser UFH stat which at the flick of
a switch(well 3) overrides the HA. Sometime maybe I'll add an RS485 link
to the stat.

The UFH is John Guest with an 8 port manifold. Each port has an on/off
24V JG actuator. These and the pump are all driven from an xAP Netiom,
via relays, controlled by the scripts. A further xAP Netiom drives the
boiler control, which is a Mitsubishi industrial logic controller.

The degree of control can be simple timed on/off through to full weather
compensation, optimum starts, individual zone/time control, etc., etc...
as I get more time!

not in every room individually.
