7.2 Configuration 2 - Room thermostat
In configuration 2 the appliance is controlled
by a external thermostat (or programmable
thermostat) (not supplied), which switches the
appliance on and off depending on the set tem-
perature (Fig. 27).
When the temperature is satisfied, the thermo-
stat opens the circuit and switches off the stove.
The stove switches back on automatically when
the temperature falls below the value set on the
external thermostat (closed circuit).
This configuration can also be used to turn
the appliance on and off manually or in a pro-
grammed way (with the Timer function active)
without the aid of an external thermostat, to do
this it is necessary to put a bridge between the
two terminals.
If the thermostat allows scheduled
programming, to avoid overlapping
operation time slots, it is advisable to
deactivate the appliance timer by set-
ting it to OFF.

In this configuration the appliance
turns off when the external thermo-
stat is satisfied, or it will modulate the
power (to keep consumption to a mini-
mum) when the set water temperature
is reached.
