Fantini cosmi Weekly Programmable Thermostats

Installation

WALL MOUNTING
Install the programmable thermostat at 1,5 meters above the floor level, far from kitchens, heat sources, windows and doors. Make sure the base is fixed to a level surface, without strains

ELECTRIC CONNECTIONS

Connect terminals 1 – 2 to the heating system with two wires thus replacing the traditional thermostat at any time and without adding further connections. When the ambient temperature increases, the relay will open terminals 1 – 2 and will close terminals 1-4. Terminal 4 is free and it may be used for signalling or other purposes, as required

OFF MODE SELECTION

When in OFF mode, Intellitherm may be set to keep a fixed temperature of 5°C to protect the system from the risk of freezing. This selection must be carried out during the installation and before inserting the batteries.

Note: if this selection is needed to be changed after the installation, Intellitherm has to be reset and reprogrammed.

MOUNTING THE THERMOSTAT BODY ON THE BASE

INSERTING AND REPLACING THE BATTERIES
Insert two long life AA 1,5V alkaline batteries, paying attention to the indicated polarity. Batteries last approximately 2 years: when they begin to run down, the battery symbol starts to flash on the display. If the batteries are not replaced within 15 days, Intellitherm C68 will switch-off automatically and the display will indicate OFF
