The ICE thermostat manages the temperature of the room where it is installed. The temperature is
regulated by commanding the heating/cooling solenoid valve via the local relay. The device can
manage two-way (common logic) heating/cooling systems as it has a single output relay.
The setpoint values used by the thermostat are stored in the device, and can be modified via the local
menu.
The thermostat offers:
• 2 types of operation: heating and cooling with independent control algorithms;
• 4 operating modes: OFF (anti-freeze / high temperature protection), Economy, Pre-comfort and
Comfort;
• 4 heating adjustment temperatures (Teconomy, Tpre-comfort, Tcomfort, Tantigelo (Tanti-freeze);
• 4 cooling adjustment temperatures (Teconomy, Tprecomfort, Tcomfort, Tprotection_high_
temperatures);
• 2 types of control: HVAC or Setpoint;
• control algorithms for 2-way systems: 2 ON/OFF points or PI proportional with PWM control;
• 1 relay output with NO/NC contact, that can be used by the thermostat to command the
heating/cooling solenoid valve;
• 1 input for a potential-free contact (for the window contact function);
• 1 input for NTC external temperature sensor (e.g. protection sensor for underfloor heating).
The thermostat is equipped with a white LED backlit display with sensitive rear-projected areas
on a glass plate. The device requires an external 12-24V AC/DC power supply. It has a built-in
sensor for measuring the room temperature, and a proximity sensor for activating the back-lighting
when the user approaches it.
