Some electric connections of the power jig have a double
function. The hot water tank circulator PB must be connect-
ed to the terminals 106-107 of the thermal module config-
ured as the Managing module. The two-way valve V1 of each
thermal module must be connected to terminals 101-102-103
for both the Managing module and the Depending module.
