I had my gas meter put in yesterday, I have installed warm water Underfloor
heating throughout .. I don't yet want to wire up all 14 zone actuators &
thermostats, and the controller.
I want to have low level heating on in the house as the days are getting
colder, my thoughts are to manually set all ground floor zones to be on at
the actuators, and then use one of the downstairs digital thermostats to
control the lot.
To leave the system ticking over at about 10-15 degrees.
The boiler is a Baxi Barcelona gas condensing unit . with pumped return,
and a 2 port valve on the flow, this feeds a thermal store (whole of store
contents circulates around boiler)
There is a separate pump for the heating circuit which circulates through a
high capacity pick up coil in the thermal store.
I guess I could knock up a mains relay to activate the boiler and both pumps
in parallel .
The programmable room stats are Danfoss TP5, which provide a pair of
contacts switching only - not a drive capability, although I could rig one
so that the mains live goes in one side of contacts and use the output (live
when demand is on) to power the relay.
Anybody any ideas on doing this . a simpler way ?
