Geca Easy 503 - ChronoThermostat Manual

GENERAL DESCRIPTION

The Easy 503 chronothermostat is a daily and weekly electronic chronothermostat that permits the programming of the temperature of your home every hour of the day, every day of the week.

The Easy 503 chronothermostat is equipped with a backlight display and a graphic visualisation of the programmed temperature that can be modified by simple and functional commands that facilitate the programming. The Easy 503 chronothermostat avoids wasting energy by activating the heating or air-conditioning system only when needed.

ELECTRICAL CONNECTION

INSTALLATION

The Easy 503 chronothermostat can be installed directly onto a threegang pattress box or wall-mounted. In both cases the recommended height from the floor is 1.5 metres in a dry place with no air currents and far away from heat sources.

INSTALLATION ONTO PATTRESS BOX 503

Fix the BASE PLATE (with the slots of the FLAP at the bottom) directly onto the threegang pattress box utilizing the type "A" screws supplied (Fig. 2).
Lift the BATTERY COVER and fix the CHRONOTHERMOSTAT UNIT to the BASE PLATE utilizing the type "B" screws (Fig. 3).
Complete the installation by lowering the BATTERY COVER.

WALL-MOUNTED INSTALLATION

After fixing the BASE PLATE (with the slots of the FLAP at the bottom) to the wall using the wall plugs and supplied type "C" screws, electrically connect the chronothermostat and fix it to the BASE PLATE using the type "B" screws. Complete the installation by lowering the BATTERY COVER.

POWER SUPPLY

The Easy 503 chronothermostat is powered by two AA 1.5V alkaline batteries that ensure the chronothermostat operates for at least two years. To insert the batteries, slide out the BATTERY COVER and position the batteries in the correct polarity direction as indicated inside the compartment (Fig. 5).

The Easy 503 chronothermostat is equipped with two battery warning discharge levels. When the first level is superseded the symbol BAT appears () whilst the chronothermostat continues to function correctly. On reaching the second level, the chronothermostat completely blocks its functions of thermoregulation whilst the display shows the hour, day and the flashing symbol of the discharged battery (). Whilst substituting the batteries, the data remains memorized for 30 seconds in the absence of power.

INITIALIZATION

As soon as Easy 503 chronothermostat is fed power it carries out a control cycle switching on all segments of the display and activating the charge for a few seconds. If the initialization might prejudice the correct functioning of the charge, power up the chronothermostat before carrying out the electrical connections.

FUNCTIONING AND PROGRAMMING

A fundamental part of the chronothermostat is the backlight graphic display that shows a diagram of 24 columns representing the 24 hours of the day and the height of each column indicates the programmed temperature for that hour.

The segment at the top on the right (A in Fig.6), in correspondence to the overprinted writing indicates the day to which the programme refers. The programmed temperature (B in Fig.6) is visualised at the top on the right whilst programming and is identified by the day flashing and the symbol "C" indicating the °C.

During normal functioning, the hour or the ambient temperature are alternately visualised by pressing the °C/h key (Fig.6).

A standard utilization diagram is shown once the Easy 503 chronothermostat is powered on; the clock starts at 00.00 of Monday (LU).

To modify the programme, move to the desired day using the DAY key (Fig.6) and adjust the daily graphic utilizing the four central keys designed in the shape of a cross. The +h and -h keys (Fig.6) shift the cursor horizontally along the HOUR axis, whilst the +°C and -°C keys (Fig.6) adjust the set temperature.

The weekly temperature programme can be modified at any moment by utilising the four central keys designed in the shape of a cross (+h, -h, +°C and -°C) and the DAY key. The minimum increase/decrease of the set temperature using the +°C and -°C keys is 0.1°C. Keeping +°C or -°C key pressed the increase/ decrease becomes 0.2°C.

After programming the first day, the following days can be programmed in two different ways:

SEGMENTS INDICATING THE DAY

LU=Monday
MA=Tuesday
ME=Wednesday
GI=Thursday
VE=Friday
SA=Saturday
DO=Sunday

COPY KEY

To copy the programme of the day that was previously programmed in other days, press the COPY key for two seconds.

The word COPY appears on the display and the cursor of the day in which the programme is to be copied flashes.

Using the +h or -h key scroll the days of the week and to confirm the DAY in which to copy the programme press the COPY key.

To exit from the COPY function, wait a few seconds without pressing any key. Having finished programming the whole week, update the hour and the day by pressing the SET key using a pointed object (Fig. 6).

SET KEY

The HOUR, MINUTES and DAY can be updated using the SET key (G in Fig.6).

Pressing the SET key, the HOUR starts flashing.

The current HOUR is adjusted the using the +°C and -°C keys.

Pressing the +h key, the programming sequence shifts to the MINUTES which starts to flash.

The MINUTES are adjusted using the +°C and -°C keys.

Pressing the +h key, the programming sequence shifts to the DAY which starts to flash.

The DAY is adjusted using the +°C and -°C keys.

From this moment the Easy 503 chronothermostat starts its normal functioning, indicating each upload inserted (heating or air-conditioning) by the lighting up of the flame symbol on the display (Fig. 6).

MANUAL FUNCTIONING

Pressing the AUT/MAN key (Fig.6) the chronothermostat goes into manual mode by closing the graphic display (which remains memorized) and lighting up the hand symbol (Fig. 6). Now the Easy 503 chronothermostat behaves like a normal ambience thermostat where the adjustment of the temperature is made by using the +°C and -°C keys (O and P in Fig.6). The set temperature read on the display remains as long as the chronothermostat is in manual mode (press the AUT/MAN key to pass to automatic mode).

ON/OFF KEY

The chronothermostat is switched off by pressing the () key (R in Fig.6) for two seconds. The Easy 503 chronothermostat will deactivate the functions relative to the set programmes, which anyway remain memorized, and will alternately visualize the word OFF with the current hour and the detected temperature. To visualize the HOUR instead of the temperature, press the °C/h key.

When the chronothermostat is switched off, the ANTI-FREEZE FUNCTION remains active. If the ambient temperature detected drops below 7°C (7°C – 0.2°C = 6.8°C), the device activates the heating system to keep the water circulating to stop ice forming in the tubes.

RESET FUNCTION

If it becomes necessary to cancel the set programme (E.G., after a programming test), simultaneously press the AUT/MAN and COPY keys (T and H in Fig.6) for approximately two seconds. The Easy 503 chronothermostat restarts the initialization procedure described previously.
