Following a heat demand from the ambient thermostat, the water from the centralised system begins to circulate in the
heat-
ing elements of the zone controlled by the user module.
For dual-zone models (R2Z – RS2Z) the heating bands of two zones can be managed separately by the relative am-
bient thermostats (or with the ECO CRONO climate adjustor).
For models RS – RSP – RS2Z (with plate exchanger), when a domestic hot water tap is opened, the user module heats
the water at the temperature set by the relative DHW potentiometer. TS temperature range: 30 ÷ 60°C (see § 16).
Different adjustments of domestic hot water temperature can be made directly using the ECO CRONO climate adjuster.
21.1 STARTING
Adjust the ambient thermostat / heating programmer / ECO CRONO climate adjuster to disable the heating function (lo-
wer the set ambient temperature or disable heating). The domestic hot water function (models RS – RSP – RS2Z) and the
frost protection device (only for RS – RSP – RS2Z) remain active).
21.2 PARTIAL SHUT-DOWN
Disconnect the appliance from the power supply by turning the luminous switch and the two-pole switch.
