Wall-mounting electronic battery thermostat suitable for temperature regulation
both in heating and cooling.
It has a configurable auxiliary input for the connection of a temperature probe or
of an external contact with which to reduce the setpoint by 3°C.
It performs actions of 1B type and is intended to operate in environments with
pollution degree 2 and overvoltage category III (EN 60730-1).

SAFETY WARNINGS
During product installation and operation it is necessary to observe the
following instructions:
1) The instrument must be installed by a qualified person, in strict compliance
with the connection diagrams.
2) Do not power or connect the instrument if any part appears to be damaged.
3) After installation, inaccessibility to the connection terminals without appropriate
tools must be guaranteed.
4) The instrument must be installed and activated in compliance with current
electric systems standards.
5) Before accessing the connection terminals, verify that the leads are not live.

88P4160199 has an auxiliary input that can be configured for connection instead
of:
- an external remote temperature probe. In this case the value measured by the
external probe is used to display and adjust the temperature.
- an external contact for the set-point temperature reduction.
Closed external contact allows setpoint reduction of 3 °C
than the set one. Display shows the symbol .
For auxiliary input configuration, see “Advanced programming” on this manual.

• Install the thermostat at a height of about 1.5 m above the floor, away from
direct sunlight, away from doors, windows, heat sources, locations with
excess or total lack of ventilation.
• Remove the front shell acting in accordance with the picture on the right.
• Make the connections by respecting the diagrams described in this manual.
• Insert the batteries in the compartment
• Fix the instrument to the wall.
• Reposition the front shell, by mating first the teeth on the upper side.
To enter menu Advanced programming keep simultaneously pressed for 3 seconds the
