TYPES OF REGULATION

Hysteresis On/Off regulation

This is the traditional ON/off operation: in winter the system is activated continuously until the desired room temperature is reached.

At this point the system will remain off until the room temperature drops below the desired temperature minus another factor called hysteresis. In summer mode the operation is reversed.

TPI regulation

The TPI is a type of regulation that ensures activation of the system for the minimum time necessary, but sufficient to maintain the room at the selected temperature.

A thermostat with TPI continuously measures the ambient temperature in which it is placed and performs a series of calculations to establish the duration of the ignition of the system to reach and maintain the set temperature, thus increasing energy efficiency.

The system will turn on for increasingly shorter periods as it approaches the correct temperature. When the setpoint temperature value is reached in the room, the system is switched on for short periods in order to maintain this temperature.

WARNINGS FOR CORRECT DISPOSAL OF THE PRODUCT

At the end of its useful life, the product must not be disposed of together with municipal waste.

It can be delivered to the appropriate separate collection centres set up by the local authorities, or to the retailers that provide this service.

Disposing of an electrical or electronic appliance separately avoids possible negative consequences for the environment and health deriving from its inadequate disposal and allows recovering of the materials of which it is composed in order to obtain the significant saving of energy and resources.

To highlight the obligation to dispose of electrical and electronic equipment separately, the product bears the crossed-out mobile waste container mark.

ORION DAY OT
PRODUCT DESCRIPTION AND TECHNICAL SPECIFICATIONS

ORION OT, in the version with daily (ORION DAY OT) or weekly (ORION WEEK OT) programming, is a chrono-thermostat designed for the remote control of modulating boilers with standard OPENTHERM communication protocol, but it can also be used in combination with appliances of Traditional ON/OFF or with TPI algorithm type control. 

This manual shows the instructions for using the device in OPENTHERM mode (factory-set). Please refer to the instruction sheet dedicated to ORION DAY / WEEK devices for all the information common to both operating modes and those dedicated to the ON/OFF operating mode only.

Power supply:
In OPENTHERM mode (modulating): 2 unpolarized boiler bus cables (OT)
In ON/OFF mode (relay): 2 x Alkaline Batteries 1.5 V LR6 (Type AAA) 

ErP Class (EU Reg. 811/2013- 813/2013):
V In modulating OPENTHERM mode (-3%)
IV In ON/OFF mode with TPI function (-2%)
I In traditional ON/OFF mode (-1%)

INSTALLATION

Before installing ORION OT we recommend to check its compatibility with the boiler: BUS communication protocols other than OPENTHERM could affect the operation of the system.

To complete the installation follow the instructions of the standard ON/OFF devices. For electrical connections, refer to the figure below, taking care to use ONLY the terminals indicated with OT for the operation in OPENTHERM mode or the NC-C-NO terminals for the operation in ON/OFF mode.

Make sure that the internal protection of the terminals is properly positioned before closing the appliance.

At the time of the first installation and during the boiler on and off phase, it may take a few seconds both to guarantee the correct modulation and for the correct acquisition of operating data.

DESCRIPTION OF CONTROLS AND DISPLAY

In the OPENTHERM mode, the functions of the keys do not change with respect to the standard ON/OFF versions. As regards the display, in addition to the icon indicating the OPENTHERM mode enabled, there are icons dedicated to the management of the heating system and the domestic hot water function.

B) Day of the week (Week version only)
C) OPENTHERM mode enabled
D) Room temperature / Operating values
E) Operating mode enabled (AUTO/MAN/OFF)
F) Hour program enabled (AUTO mode)
G) Parameter setting (SET)
H) Fixed ON = Heating mode enabled
Flashing = System in operation
L) Fixed ON = Domestic hot water mode enabled
Flashing = Sanitary water drawing in progress
M) Boiler control enabled

DEVICE ACTIVATION

For the operation in OPENTHERM modulating mode, the appliance is powered directly by the boiler to which it is connected and does not require batteries. In this mode, depending on the boiler characteristics, the display backlight could be reduced or excluded. For the use in ON/OFF mode, the appliance must instead be powered by two alkaline batteries of AAA type, properly inserted in the dedicated compartment.

When the device is switched on, all the segments and symbols of the display are shown for a few moments, followed by the indication of the software version in use before the request to set the clock.

Follow the instructions of the standard ON/OFF models for the initial settings and the management of the MANUAL (MAN) or AUTOMATIC (AUTO) operating modes with the relative programming of the time slots.

CHANGE THE OPERATING MODE

The device is factory-prepared for operation in modulating OPENTHERM mode.

This setting can be easily changed at any time if you choose to use the appliance in the traditional ON/OFF mode. In this case, after separating the front part of the thermostat from the wall base, insert the batteries in the appropriate seat as indicated in the instructions of the standard ON/OFF devices and make the correct electrical connections as shown in the INSTALLATION chapter.

When you switch on the device, during the display phase of the software version in use, press the ‘MENU’ and ‘LEAF’

keys simultaneously and keep them pressed until the three dashes confirming the correct execution of the command are displayed. At this point the thermostat will restart with the new operating mode.

The confirmation of the actual setting is found in the encoding (first character) of the Software version in use, visible after turning on the device, as indicated below:

Software version indication for operation in OPENTHERM mode

Software version indication for operation in Standard ON/OFF mode

Perform the same procedure to return to the Software version suitable for the OPENTHERM operating mode, REMOVE the BATTERIES and make the correct electrical connections (see INSTALLATION chapter) before connecting the thermostat to the boiler.

SETTING MENU AND OPENTHERM PARAMETERS VISUALISATION

Use the ‘LEAF’ key to put the device in MAN mode or in OFF mode and press the ‘MENU’ key to enter the setting menu.

INSTALLER MENU  

WARNING: CHANGING THE PARAMETERS CONTAINED IN THIS MENU MAY AFFECT THE OPERATION OF THE DEVICE.

Follow the instructions of the standard versions ON/OFF to access the INSTALLER MENU and to manage all the parameters except the P04 one (selection of the ADJUSTMENT TYPE) not available for the OPENTHERM version of the device.

VISUALISATION OF THE ALARMS

During normal operation, the device performs a continuous self-diagnosis, highlighting any anomalies on the display with the words ™AL0∫ followed by a number.

The visualisation on the display of alarm codes other than 0 indicates anomalies on the system or on the boiler and are transmitted to the device by the boiler itself. In this case, the type of anomaly found and any suggestions are to be found in the boiler instruction manual. 

The device is reset when the error conditions are cleared. 

The visualisation of the word ™AL0∫ on the display indicates the momentary lack of communication with the boiler and all the functions of the device are blocked (alarm managed directly by the device only in OPENTHERM mode). 

The activation of this alarm during the first power-up phase may be due to:

• Type of boiler not compatible with the standard OPENTHERM protocol
• Inconsistency between the expected operating mode (OPENTHERM or ON/OFF) and the selection of the correct software on the device 
• Presence of batteries with device Software set for OPENTHERM operation.

If after checking the settings it is necessary to change the selection of the operating mode of the device (effectively resetting the alarm status), proceed as indicated in the OPERATING MODE CHANGE chapter.

TROUBLESHOOTING

Reactivation of the device after the lack of power supply: 

• In use in OPENTHERM mode: lack of mains voltage/shutdown and subsequent boiler restart
• When using in ON/OFF mode: insertion/replacement of batteries 

After each restart the device requires the clock to be reset in order to be able to correctly run the preset time programs. If this procedure is not correctly performed or completed within 10 minutes, the device will activate in MANUAL mode (MAN), displaying the flashing clock and the value of the ambient temperature on the display. Then, pressing any key will allow you to set the clock and return to normal operation.

Failure to turn on the display:

• When using in OPENTHERM mode, ensure that the connections made both on the thermostat (see INSTALLATION chapter) and on the boiler are properly performed and that the boiler is operating.
• When using in ON/OFF mode, check that the batteries are efficient and correctly inserted in the appropriate compartment.

In case of suspected anomalies during operation, restart the appliance:

• When using in OPENTHERM mode, remove and restore power by separating the front part of the device from the wall base for a few moments.
• When using in ON/OFF mode, remove the batteries for a few moments.
