5.2 - Automatic or manual operation of the time programmable thermostat

Using key K2, it is possible to enable or disable the time-programmable thermostat of the remote control in cyclical mode. This can be noted from the display of the histogram bar of the time-programmable thermostat (automatic position), alternatively from the display of the hand (manual position) The function only becomes available in the “heating with domestic hot water” and “only heating” modes. The function is not active in the “only domestic hot water” mode. Consult section 5.8 for the programming of the time-programmable thermostat . When the remote time control is in the MANUAL position (hand designed on the display), just use the K+ o K- keys for increasing or decreasing the temperature required.

5.3 - Adjusting the domestic hot water temperature

Using key K4, with the remote control positioned in any operating mode (excluding OFF mode), it is possible to select the menu for setting the domestic hot water temperature. The display shows the wording REG SAN and the domestic hot water temperature value; using keys K+ o K- it is possible to change these values between 40 and 65 °C. Use the KM key to save the data and return to the operating mode.

5.4 - Manual forcing of room temperature (overrun function)

This function only becomes available if the “heating mode” is enabled (see section 5.1) Having activated the automatic functioning of the time-programmable thermostat (see section 5.2) of the remote control (AUTO mode), using keys K+ o K-, the display will show TEMPER AMBIENTE and the room temperature value. By pressing K+ o K- once again, it is possible to temporarily change the room temperature required; in this way, the automatic functioning of the time-programmable thermostat is by-passed (overrun), forcing a manual setting value, until the following change of status requested of the timer of the time-programmable thermostat. Return to the operating mode takes place automatically, after 5 seconds, or manually using the KM key. If the temperature value has been changed, the display will show the hand symbol and the programming bar of the timer (see figure 3, detail 1 1) so as to indicate that the function in question is underway (the hand symbol disappears the next time the status of the time-programmable thermostat’s timer changes).

5.5 - Forcing of heating programme

Using the KM key , it is possible to access page 1 of the menus and from there, using key K1 (RIS), one accesses the heating forcing menu. Once this menu has been selected, it is possible to make the following choice:

· TIMER Return to the operating mode takes place automatically , af ter 2 minutes, or manually using the KM key. By pressing key K4 (TIMER), the TIMER heating mode function is enabled; effectively, the manual functioning of

the time-programmable thermostat is forced for a given period of time set on DURA TION using the K+ e K- keys, at a room temperature value set by pressing key K4 (TMP) and adjusted as always using the keys K+ e K-. Now the running of the boiler will depend on the room temperature selected and the duration of the time set on the timer. Return to the operating mode takes place automatically , af ter 2 minutes, or manually using the KM key. The display shows the wording TIMER RIS for the duration of the forced heating set on the TIMER, or , in the event that the domestic hot water timer function is active, the wording TIMERS. Once the time set on the TIMER has elapsed, the heating returns to that active before the setting. It is possible to interrupt the function in question at any given time; in order to do this, after having selected the RIS – TIMER heating mode (key KM followed by key K1), press key K1 (OFF). The remote control automatically returns to the operating mode.

5.6 - Forcing of domestic hot water programme

Using key KM, it is possible to access page 1 of the menus and from there, using key K2 (SAN), one accesses the domestic hot water forcing menu. This menu is enabled only if the selection parameter of the domestic hot water operating mode (PROG SAN) is set at 2 or 3 (see section 5.9). Once this menu has been selected, it is possible to make the following choice:

· AUTO

· TIMER By pressing key K1 (AUTO), the automatic functioning of the domestic hot water mode is obtained.

In relation to the PROGR SAN parameter set (see section 5.9), the AUTO domestic hot water mode can adopt 2 different operating features:

- follow an independent timing programme

- follow the setting of the timing programme of the heating service The activation of the AUTO domestic hot water mode is indicated on the display when the clock

symbol lights up. It is possible to interrupt the function in question at any given moment, re-setting the continual function (always ON) of the domestic hot water mode. In order to do so, after having selected the domestic hot water mode SAN – AUTO (key KM followed by key K2), press key K1 (ON); the remote control automatically returns to the operating mode.

By pressing key K4 (TIMER), the TIMER domestic hot water operating mode is enabled; in practice, the operating

of the domestic hot water mode is forced for a given period of time. The display shows the DURA TION p arameter which can be selected by using key K1 (DURATION); the flashing off said parameter indicates its selection and the possibility of changing it using the keys K+ o K-. The DURA TION parameter can adopt a value ranging between 30 minutes and 12 hours. Return to the operating mode takes place automatically, after 2 minutes, or manually using the KM key . The activation of the TIMER domestic hot water mode is indicated on the display when the TIMER SAN wording lights up, or, in the event that the heating timer function is also active, the TIMERS wording is shown. Once the timing has elapsed, the domestic hot water mode returns to that active before the setting of the TIMER domestic hot water mode. It is possible to interrupt the function in question at any given moment. In order to do so, after having selected the domestic hot water mode SAN – TIMER (key KM followed by key K2), press key K1 (OFF); the remote control automatically returns to the operating mode

5.7 - System parameters’ consultation

All the afore-mentioned operating parameters are memorized within an Eeprom-type memory , which stores them even if the power to the remote control is cut.

Possible values adopted by the afore-mentioned variables:

(1) It is not possible to set the maximum value of the TMP MIN RIS parameter greater than the minimum of the REG RISCALD parameter. V ice versa, it is not possible to set the minimum value of the REG RISCALD parameter lower than the maximum value of the TMP MIN RIS parameter. (2) The function is subject to the management of said parameter by means of the boiler control board to which the remote control is connected.

6.2.1 - Thermoregulation - Setting the gradient

Pressing key KM down for 10 seconds and then key K2 (IMP), the CURV A EST parameter is immediately displayed. Using the keys K+ o K- , it is possible to change the setting. The graph in figure 4, shows the ratio between the external temperature and the supply temperature calculated in relation to the value assigned to the CURV A EST parameter. The installer can use this graph in order to establish the exact CURVA EST to be set in relation to the geographic area where the installation will take place (typically , the curves chosen for Italian regions range between 0.6 and

1.1 for radiant panel systems). The adjustment of the supply temperature in relation to the external temperature is active only if the MODO FUNZ parameter is set at 3 (see section 6.2.3)

Figure 4 - Ratio between supply temperature and external temperature

Normally, the adjustment of just the CUR V A EST (gradient) as per the graph in figure 4, is not enough to adjust the supply temperature exactly, in relation to the external temperature. For this purpose, it is possible to adjust the parallelism of this line as well, taking action directly on the remote time control, requesting a room temperature other than 20°C. Figure 5 shows how the line (in this case with a CURVA EST gradient = 2.0) can move on a parallel in relation to the temperature set on the remote control. To set the temperature on the remote control, see section 5.2, or 5.8.

This type of setting is advisable above all else for radiant panel systems, where the remote control cannot be positioned as a sensor of a characteristic room temperature, or in situations where there are thermostats which regulate the temperature zone by zone.

6.2.2 - Thermoregulation - Correction with room temperature

Pressing key KM down for 10 seconds, then key K2 (IMP) and finally key K4 (>>) the COMPENS AMB parameter is displayed immediately. Using keys K+ o K-, it is possible to change the setting. When the value of the COMPENS AMB parameter differs from 0, the compensation of the room temperature is active. The effect of the room temperature compensation is the automatic parallel shift of the curve as per figure 4. In this way , the parallel translation of the line, which in the previous section was carried out manually , is now made automatically on the basis of the temperature registered by the remote control in the room. The shifting of the curve, defined as Delta, is calculated on the basis of the error between the value of the room temperature requested and that actually read by the remote control. The Delta is also influenced by the parameter defined as room compensation (COMPENS AMB) which can be selected from between 0 and 20 (as can be seen from the graph in figure 6). The rules for the correct setting of the room compensation value (COMPENS AMB) are:

· the compensation of the room temperature makes it possible to put the heating system in steady state much faster and automatically compensate the imperfect selection of the CURVA EST;

· the higher its value, the quicker the putting of the heating system in steady state is;

· too high a value may cause the system to react too quickly, involving the consequent sudden igniting and switching off of the boiler;

· generally, a large heating system, which requires a long period before it reaches steady state, requires a higher room compensation value with respect to a smaller heating system which requires a shorter period before it reaches steady state;

· the room compensation works correctly only if the CURVA EST has been correctly chosen. The room compensation is active only if the MODO FUNZ parameter is set at value 3 (see section 6.2.3)

This type of adjustment is advised for all radiant panel type systems where the remote time control can be installed in an area where the temperature is characteristic of the entire area to be heated.

6.2.3 - Thermoregulation - Choosing the operating modes

The MODO FUNZ parameter is one of the most important to be adjusted. On the basis of the setting of this parameter, the type of thermoregulation to be used in the system is chosen. Therefore, it is indispensable to choose the type of thermoregulation carefully , in relation to the type of system owned, in order to achieve the best degree of comfort envisaged. Pressing key KM down for more than 10 seconds, then key K2 (IMP), and subsequently key K4 (>>) until MODO FUNZ is displayed, it is possible to select, using keys K+ e K-, one of the 4 types of thermoregulation available: 1 · room thermoregulation with set supply temperature 2 · room thermoregulation in relation to the room temperature 3 · room thermoregulation in relation to the external temperature, with or without room temperature 4 · thermoregulation with exclusion of the room temperature and two-point adjustment

Room thermoregulation with set supply temperature (MODO FUNZ = 1)

The user sets the room temperature desired and the remote control generates a heat request to the boiler (pump comes on), every time the room temperature falls below the temperature requested. Vice versa, every time the room temperature rises above that set, the remote control interrupts the heat request to the boiler (pump switches off). In this operating mode, the supply temperature to the radiators is set at the value set on the REG RISCALD parameter (see section 6.2). This type of thermoregulation is recommended for a system with radiators or convector fans

Room thermoregulation in relation to the room temperature (MODO FUNZ = 2)

The heating supply temperature is calculated using a PID type algorithm so that the room temperature, read by the remote control, corresponds with that set by the user; the value calculated corresponds to the value of the heating supply temperature (TEMP CALC parameter , see section 6.1). This value however is always limited to the value set on the REG RISCALD parameter (see section 6.2.8). This type of thermoregulation is recommended for systems with radiators, convector fans or radiant panels where the temperature of the room where the remote time control is located is characteristic of all the rooms heated.

Room thermoregulation in relation to the external temperature, with or without room temperature (MODO FUNZ = 3)

The heating supply temperature is calculated using a formula which takes into account the CURV A EST selected (see section 6.2.1); the value calculated (TEMP CALC parameter , see section 6.1) corresponds with the setting of the heating supply temperature. This value however is always limited to the value of the REG RISCALD parameter set (see section 6.2.8). In this operating mode, if the COMPENS AMB parameter (see section 6.2.2) is set at zero, the adjustment of the supply temperature is made without considering the room temperature read by the remote control. Therefore, the installer will have to find the right angle of the line, adjusting the CURVA EST parameter as per section 6.2.1 and the right parallelism, adjusting the room temperature as per sections 5.2 and 5.8. This type of thermoregulation is recommended for a system with radiant panels where the rooms heated are served by room thermostats which act on the area valves, or in systems where it is not possible to install the remote control in a place where the room temperature registered is characteristic of the building. In such cases, the supply temperature is adjusted exclusively in relation to the external temperature according to the ratio shown in the graphs as per figures 4 and 5.

If the COMPENS AMB parameter (see section 6.2.2) is set at a value other than zero, the room temperature registered by the remote time control intervenes to correct the supply temperature on the basis of the matters already illustrated in section 6.2.2 and figures 6 and 7. This type of thermoregulation is recommended for a system with radiant panels where the temperature of the room in which the remote time control is located is characteristic of all the rooms heated.

In all the afore-mentioned cases, when the external temperature is greater than the calculated supply temperature (parameter TEMP CALC as per section 6.1), the heating is shutdown.

Thermoregulation with exclusion of the room temperature and two-point

adjustment (MODO FUNZ = 4)

The room temperature and the external temperature do not interact on the operating mode of the thermoregulation in question. The adjustment of the supply temperature to the radiators is carried out at two temperature levels, set respectively at TMP MIN RIS (minimum supply temperature, see section 6.2.7) and REG RISCALD (maximum supply temperature, see section 6.2.8). The meaning usually attributed to the parameters TMP AMB T0, TMP AMB T1 and TMP AMB T2 (room temperature levels which can be selected for the automatic operating mode of the room thermostat, see section 5.8), changes as indicated below:

TMP AMB T0 = heating request absent TMP AMB T1 = heating request present with supply adjustment at value of TMP MIN RIS parameter TMP AMB T2 = heating request present with supply adjustment at value of REG RISCALD parameter By means of the programming of the heating timer (see section 5.8), the user establishes when, over a period of

24 hours, to set the boiler going in heating mode (levels T1 or T2) or not (level T0) and what the setting of the supply temperature must be (TMP MIN RIS or REG RISCALD) for the water of the heating system.

When this thermoregulation operating mode is selected:

- the PRE RISCALD function (see chapter 6.2.6) is automatically disabled;

- the programming of the TMP AMB T0, TMP AMB T1 and TMP AMB T2 parameters as per section 5.9, is automatically disabled;

- during the manual adjustment of the room temperature, as per section 5.2, it permits the adjustment of the desired room temperature, at three levels corresponding to 0 = TMB AMB T0, 1 = TMP AMB T1 and 2 = TMP AMB T2.

6.2.4 - Hour type displayed

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until TIPO ORA is displayed, it is possible to select, using keys K+ e K-, the 12 hours or 24 hours timing display. Setting the parameter at 1, one obtains the 24 hour display, whilst setting it at 2 the 12 hour display is shown.

6.2.5 - Domestic hot water programme type

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until PROGR SAN is displayed, it is possible to select, using keys K+ e K-, the operating of the domestic hot water function, in the following manner: 1 = domestic hot water service always active; 2 = possibility of carrying out the time programming of the domestic hot water service independently from the

heating service (the function, when active, is shown on the display using the clock symbol). For the programming

of the domestic hot water service, refer to section 5.8; 3 = the domestic hot water service follows the time programming made for the heating service exactly. Due to how the boiler is conceived, it is advisable to keep the parameter at 1 or 3.

6.2.6 - Automatic pre-heating

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until PRE RISCALD is displayed, it is possible to select, using keys K+ e K-, the type of pre-heating one intends to carry out. The parameter can adopt the following values: 1 = pre-heating enabled in adaptive mode; 2 = pre-heating enabled with a ramp of 3°C/hour; 3 = pre-heating disabled.

If this parameter is set at 3, during the time programming of the heating function, the user must bear in mind to switch on the heating in advance with respect to the effective need, due to the thermal inertia of the plant (high in the case of radiant panels, low in the case of radiators, uninfluential in the case of convector fans). So as to avoid having to take these times into consideration, being among other things difficult to calculate and variable in relation to the season and type of plant, it is advisable to keep the parameter at the value of 1 or 2, where the remote time control carries out an automatic detection of the system’s features (with a frequency of 10 minutes), thus calculating the thermal inertia, or the time necessary for achieving a specific room temperature. In

this way , when the time programming is carried out it will be sufficient to introduce the switching on and switching off of the heating in correspondence with the time period of effective need; the remote time control will automatically take steps to bring forward the ignitions so as to obtain the desired room temperature, in the time period set.

6.2.7 - Minimum supply temperature

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until TMP MIN RIS is displayed, it is possible to select, using keys K+ e K-, the minimum supply temperature for the heating. It is recommended that it be left at 20°C. Only in the event that the MODO FUNZ parameter (see section 6.2.3) has been set at 4, the TMP MIN RIS must be adjusted to the supply temperature, corresponding to the energy saving timeband TMP AMB T1.

6.2.8 - Maximum supply temperature

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until REG RISCALD is displayed, it is possible to select, using keys K+ e K-, the maximum supply temperature for the heating. It is recommended that it be left at 45°C. In the event that the MODO FUNZ parameter has been set at 1 (see section 6.2.3), the REG RISCALD must be adjusted to the supply temperature, corresponding to the adjustment temperature. In the event that the MODO FUNZ parameter has been set at 4 (see section 6.2.3), the REG RISCALD must be adjusted to the supply temperature, corresponding to the comfort timeband TMP AMB T2.

6.2.9 - Pre-setting of room temperature

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until TMP AMB T0/T1/T2 is displayed, it is possible to select, using keys K+ e K-, the room temperature values, envisaged during the time programming of the heating function (see section 5.8). The operation for adjusting TMP AMB T0, TMP AMB T1 and TMP AMB T2, corresponds with the same regulation as per section 5.9. If the MODO FUNZ parameter has been set at 4 (see section 6.2.3) the adjustment of TMP AMB T0, TMP AMB T1 and TMP AMB T2 is disabled.

6.2.10 - Pre-setting of domestic hot water temperature

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until REG SAN is displayed, it is possible to select, using keys K+ e K-, the exit temperature of the domestic hot water between 40 and 65°C. The function corresponds with the adjustment of the domestic hot water as per section 5.3.

6.2.11 - Pre-setting of system supply type

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until RIEMPIMENTO is displayed, it is possible to select, using keys K+ e K-, the following values: 1 = manual 2 = automatic 3 = disabled

If the boiler comes with an automatic valve, for filling the heating circuit, with the RIEMPIMENTO parameter set at 2, the remote time control takes steps to carry out the filling of the boiler each time the water pressure drops below a pre-established value. In the event that the parameter is set at 1or 3, the filling of the system must always take place manually (follow the boiler instruction manual, so as to carry out the filling of the heating circuit’s system).

6.2.12 - Correcting the room temperature read

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until CORR TAMB is displayed, it is possible to select, using keys K+ e K-, the correction of the reading of the room sensor, with respect to the actual temperature. If the room temperature read by the remote time control is influenced by the installation position (e.g. installation on a wall which faces outside, installation on a thermal brigde, etc.) it is possible to correct the temperature of a value by more or less two degrees, using the CORR TAMB parameter.

6.2.13 - Factory settings

Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until IMP FABBRIC is displayed, it is possible to select, using keys K+ e K-, whether to re-set the initial factoring settings. If during the programming of the remote time control, programmings or adjustments are carried out so that the system no longer correctly functions, it is possible to reset the initial factory settings, so as to re-start from a known programming basis. During the selection of the IMP F ABBRIC parameter , you will be requested to set the language, the day of the week and the current time once again.

Once the factory settings have been re-set, it is necessary to re-set the recommended settings as per the table in section 6.2.

6.3 - Diagnostics
