Shared or individual pumps (Base PRO with
interface only)
A pump for all manifolds and controllers can be
connected to the closest controller.
If separate pumps are used for each manifold, each
pump can be connected to be run by its own controller,
as shown in the illustration below.
The controller includes a boiler relay, it can be used to
send a signal to either fire the heat source or to power
open a 2-port motorised zone valve positioned on the
flow to the underfloor heating manifold. If the relay
is used to power open a zone valve then, the volt free
auxiliary contacts on the zone valve should be used to
fire the heat source.
Alternatively, the boiler relay can be used to send
a demand signal to an electrically operated water
temperature controller. The additional contacts on the
water temperature controller should then be used to fire
the heat source.
The boiler can be connected to the controller.
The illustration below shows how to connect a boiler to
the controller.
