For the connection of the devices connected to the jig
(pumps, circulators and diverting / mixing valves) use inter-
posed relays unless the maximum absorption of all compo-
nents connected to the board (including the module circu-
lator) is less than or equal to 1.5 A. Relays sizing lays on the
installer depending on the type of connected device.
