DIYbanter - View Single Post - Central Heating controller for multiple zones?

The message
from (Alan Braggins) contains these words:

At the moment upstairs has three heating zones, each with a Danfoss TP5
5/2day programable thermostat connected to the central control box,
which controls the zone valves at each manifold, and switches the
heating circuit pump when any zone thermostat switches, and is supposed
to switch the boiler pump when the cylinder thermostats switch, but
actually runs it the whole time at the moment (so the cylinder temperature
is actually set by the boiler thermostat - not ideal).

You don't need another controller if you have the programmable
thermostats wired up properly. IIRC the thermostat controls the zone
valve and the zone valve controls the boiler just as it would if you
only had one zone.

My experience is with radiators but I don't see why the basic controls
for underfloor heating should be different. (I only have 2 heating
zones. Downstairs controlled by a TP75 and upstairs by a cheapo from
Screwfix.)
