'0FS2' IMPOSTAZIONE OFFSET DELLA SONDA REMOTA

This device is an electronic daily chronostat with an ample backlit display for showing the room temperature reading or current time, as desired.

The room temperature can be set in the Heating or Cooling mode on two different levels: Comfort and Economy.

In addition, the device offers the option of setting the Antifreeze temperature and adjusting the Offset value on the internal sensor.

INSTALLATION

The device is designed to be installed in a standard recess (or wall) mounted junction box with two or three modules or else directly on the wall using the screw anchors provided.

To install the device carry out the following steps:

• Release the wall plate fitted under the base of the timer thermostat as shown in Fig. 2.
  Fix the plate directly to the wall or a 3-module flush connection box using the two screw fastening holes with centres spaced 60~mm or 85~mm apart (Fig. 3), taking care to thread the wires through the slot as shown in Fig. 3.
• Make the electrical connections following the connection layout shown in Fig. 4.
• Bring the timer thermostat near the wall plate, first matching up the teeth on the base with the holes in the plate, and then pressing downward on the device until the plastic teeth snap into place; then fix the chronostat body to the wall mount plate through the two screws supplied which must be mounted in the battery holder (Fig. 3).
• Insert the batteries in the battery compartment (M in Fig. 1); see

paragraph 'HOW TO INSERT/REPLACE THE BATTERIES'.

The chronostat must be positioned about 1.5m above floor level, away from sources of heat, doors and windows.

STARTING

When operating the device for the first time:

Fit the batteries into the compartment provided, observing proper polarity (Fig. 1). Reset the device by inserting a pointed implement through the hole provided (L on Fig. 1); DO NOT USE NEEDLES.

There are three control buttons beneath the lower cover 3:

'OK': Programming/Time/Confirm (I on Fig. 1);

Pressing button for at least 4 seconds will instead activate the 'Cooling' function and the symbol will appear flashing on the display.

Setting the Comfort and Economy modes

The timer thermostat has 24 switches (A on Fig. 1), situated alongside the display, for programming operation in the 'Comfort' or 'Economy' modes at different times of the day.

When you want the timer thermostat to operate in the comfort mode, for example during the daytime, move all the switches corresponding to the desired time interval over to the right.

If you want the timer thermostat to operate in the economy mode, for example during the nighttime, just move all of the switches corresponding to the desired time interval over to the left.

In this case it is sufficient to remember the following rule:

Switches positioned to the right: The comfort setting is enabled in the automatic operating mode.

Switches positioned to the left: The economy/night setting is enabled automatic operating mode.

Each switch corresponds to the interval falling between the times printed above and below the switch itself.

For example, note that the time interval from 00 to 05 is controlled by a single switch, whereas from 05 to 09 in the morning settings can be made at half-hour intervals. For the rest of the day, the selectable time intervals are one hour each (A on Fig. 1).

The Comfort temperature is set by means of knob ' (Sun), whereas the Economy temperature is set by means of knob ^ (Moon).

Normally, in order to have a reduced temperature at nighttime, knob 'C' will be set on a lower value than knob 'O'.
