GENERAL INFORMATION

General notices

Please read this manual before installing and using the device.

• Risk of electric shock. This device should be installed by a qualified professional and in line with the standards in force for electrical installations. Always disconnect the power supply before installing.
• Note to the installer:
  • Most of the product parameters are factory set. If the device is activated without a WiFi connection, the date and time should be set on the thermostat as a minimum (this information is wiped every time the batteries are removed and if not updated via the web). All other settings
  • such as linking the receiver and the transmitter (for the WiFi Box), usage mode and temperatures – are pre-configured.
• These instructions must be read together with the sections of the boiler manual regarding the room thermostat/boiler remote control. It is recommended that the device be installed by qualified technicians.
• The Hi, Comfort T100 should be installed in the most accessible room for you as regards controlling the room temperature (usually the living room).
• As per the standards, the Hi, Comfort T100 should be positioned 1.5 m from the floor to make sure that you can easily read the display.
• The Hi, Comfort T100 is powered by 2 x AA batteries.
• The Hi, Comfort T100 must be kept away from sources of heat or air currents as these may affect the accuracy of the readings from the incorporated room sensor.
• Do not open the Hi, Comfort T100 for any reason, unless to replace the batteries; it does not require any maintenance to operate.
• Do not press on the liquid crystal display glass as this may damage the glass and cause problems with reading the display.

• With the WiFi Box connected in OTBus mode to the boiler via cable, should there be a power outage, the WiFi box remains in the last operating mode

What is the Hi, Comfort T100 for?
The Hi, Comfort T100 allows you to check the temperature in your house and the operation of your boiler without you needing to access it. For reasons of space optimisation, your boiler may be located outside (for example, on a terrace or balcony or in an outdoor space); the Hi, Comfort T100, on the other hand, is usually installed in the largest room in the house, where it can be easily checked and adjusted. Where installed in systems with a boiler which is not equipped with the specific communication bus, the Hi, Comfort T100 only allows you to check the temperature in your house and does not allow you to control the boiler remotely (domestic hot water temperature and boiler settings/ alarms cannot be managed). For both types of installation, the Hi, Comfort T100 system allows you to check the temperature in different zones in your house, where there are zone valves and each one of these is connected to a single additional Hi, Comfort T100 (multi-zone management). If the Hi, Comfort T100 is installed together with the WiFi Box and you have a WiFi internet connection in your home, the Hi, Comfort T100 system allows you to carry out the same functions available via the Hi, Comfort T100 itself remotely on a smartphone.

Modes of use
The Hi, Comfort T100 means you can manage your domestic heating in a more sophisticated way; you can decide how and when the boiler will come on to heat your living spaces. In addition, it allows you to set the domestic hot water temperature, without having to access the boiler panel (where connected to the boiler via OTBus or a specific communication bus). The purpose of this manual is to explain each of these ways of using the device and the related functions.

Glossary of technical terms

• Heating water: the water in the radiators that has been heated by the boiler. Domestic hot water: the water heated by the boiler which is dispensed from the domestic taps.
• Fault code: this code shows on the display to flag any boiler or Hi, Comfort T100 faults.
• Original set-up: this is the control panel configuration after turning on the device for the first time or after a reset.
• Display: this is the liquid crystal panel where each of the symbols corresponding to the various functions are shown.
• Anti-freeze function: this function ensures that any drops in temperature do not cause the water inside the pipes to freeze and cause damage to the heating system. This function is activated when the room temperature drops below 5°C (this value can be changed by the qualified technical service).
  NOTE
  This function is active only if the boiler is in the correct operating condition (i.e. powered and not blocked).
• Restore factory settings: this restores the control panel to its original set-up, resetting any user programming excluding the system clock.
• Summer: the heating system is not active in this mode (for example, during the summer). The boiler can dispense domestic hot water. If correctly connected and configured (in cooling mode), the Hi, Comfort T100 can be used to manage a cooling system in the summer, turning the relay on in ON/OFF mode, in the opposite way to the winter operating mode. The relay keeps the user request connected (e.g. a zone valve) until the room temperature falls below a certain level. The cooling mode requires a specific system and generator for this purpose.
• Winter: the Hi, Comfort T100 dispenses domestic hot water and hot water for heating in this mode.
• T1 anti-freeze temperature: this is the temperature used when the rooms are not lived in.
• T2 economy temperature: this is the temperature used when the rooms are not lived in during the day, at night or when you are on holiday.
• T3 comfort temperature: this is the temperature at which you obtain ideal room heating during the day.
• Room temperature: this is the temperature in the room where the Hi, Comfort T100 is installed (see “NOTE 1” to page 7). Room setpoint temperature: this is the desired room temperature.
• External temperature: this is the temperature outside, read using an external probe connected to the boiler or read in another way (see “NOTE 2” to page 7).
• Heating curve: this is the relationship between the external temperature and the heating flow temperature. Where external temperature data are available (via an external probe or other method), the heating flow temperature is automatically adjusted as the external temperature varies in order to maintain a constant temperature in the room. The heating curve must be set by the installer on the basis of the geographical location and type of system.
• Connection via OTBus communication bus: this is a communication mode between the Hi, Comfort T100 and the boiler, where a series of information is exchanged between the two electronic systems. This proprietary connection can be used as opposed to the simple ON/OFF (open/closed contact) and is set by the boiler manufacturer specifically for the Hi, Comfort T100. Check the compatibility of your boiler with the OTBus connection first.
• ON/OFF connection (boiler room thermostat): this is the simple communication method between the Hi, Comfort T100 and the boiler (or any other unit capable of receiving this command), where the relay on the Hi, Comfort T100 (or on the WiFi Box/receiver) sends an on/off request via the room thermostat (TA) contact on the boiler. The ON/OFF connection is also used when a request is made to another system component such as a zone valve or similar. The Hi, Comfort T100 ON/OFF contact always maintains the same technical characteristics (Hi, Comfort T100 relay, WiFi Box relay, boiler RF receiver relay) wherever it is positioned and these must be respected when connecting the relay and the components it controls via cable.
  NOTE: Never exceed the maximum electrical loads.

NOTE 1
The display range for the room temperature is between -7°C and +50°C.

NOTE 2
The display range for the external temperature is between -40°C and +60°C. Temperatures outside of these ranges are shown as three dashes “- – -”.

Definition of classes

• Class I – On/off room thermostat: a room thermostat that controls the on/off operation of a heater. Performance parameters, including switching differential and room temperature control accuracy are determined by the thermostat’s mechanical construction.
• Class V – Modulating room thermostat, for use with modulating heaters: an electronic room thermostat that varies the flow temperature of the water leaving the heater dependent upon measured room temperature deviation from room thermostat set point. Control is achieved by modulating the output of the heater.
• Class VI – Weather compensator and room sensor, for use with modulating heaters: a heater flow temperature control that varies the flow temperature of water leaving the heater dependent upon prevailing outside temperature and selected weather compensation curve. A room temperature sensor monitors room temperature and adjusts the compensation curve parallel displacement to improve room comfort. Control is achieved by modulating the output of the heater.
• Class VIII – Multi-sensor room temperature control, for use with modulating heaters: an electronic control, equipped with 3 or more room sensors, that varies the flow temperature of the water leaving the heater dependent upon the aggregated measured room temperature deviation from room sensor set points. Control is achieved by modulating the output of the heater

Three-phase installation

Preparation
Before installing the device Check that the thermostat is compatible with the boiler (see boiler installer manual). The wireless Hi, Comfort T100 thermostat can be installed anywhere, however the most suitable place should be chosen taking into account the following:

• Avoid draughts (A).
• Do not install above sources of heat (B).
• Avoid direct sunlight (C).
•  Position at the appropriate height (D).

The following tools are required:

• Phillips screwdriver
• Small slotted screwdriver
• Pliers and wire strippers

Installing the Hi, Comfort T100
Remove the Hi, Comfort T100 from its base;

Fix the Hi, Comfort T100 base to the wall or electrical box using the screws provided. Using screws other than those PROVIDED may compromise the correct closure of the plastic. Make sure that the screw head is correctly inserted in the hole.

The Hi, Comfort T100 can be installed in one of the following ways:
Wireless
No wiring is required. Please check the maximum openfield distances shown in the Hi, Comfort T100 thermostat technical data. Loss of radio frequency communication is flagged with alarm E82. Distances which exceed the maximum may occasionally generate an E82 alarm, causing incorrect system operation.

Wired in ON/OFF mode (room thermostat contact on Hi, Comfort T100 base) When replacing old thermostats or as a new wired ON/OFF installation. The Hi, Comfort T100 can be connected to a boiler, zone valve or other device. The electrical load on the Hi, Comfort T100 room thermostat contact must not exceed the specifications for the relay itself (see “2.3 Technical Data” to page 33). Should the electrical load not be compatible with the technical characteristics indicated in the Hi, Comfort T100 thermostat technical data, it is recommended that you use an additional separation relay. Connect the cables from the boiler room thermostat terminal or the power supply for any zone valves to the Hi, Comfort T100 room thermostat terminal.

Wired in OTBus mode (OTBus contact on Hi, Comfort T100 base). Direct connection via two wires to the boiler equipped with the same communication protocol. We recommend checking the maximum cable length between the WiFi Box and the boiler OTBus terminal or Hi, Comfort T100 and the boiler OTBus terminal (see “2.3 Technical Data” to page 33). For the electrical connection to the boiler, please see the boiler manual. A wired connection via OTBus between the Hi, Comfort T100 and the boiler is recommended in the absence of a WiFi Box. With the above connection and a WiFi Box, only one zone can be controlled and operation via the APP is not guaranteed.

Insert the 2 x AA batteries provided, with correct polarity

Fit the Hi, Comfort T100 onto the base

Installing the WiFi Box

Description of the WiFi Box
The WiFi Box communicates with the Hi, Comfort T100 thermostat or with the boiler RF receiver only via radio frequency (wireless).

OUTPUTS
The WiFi Box contains a relay (see “2.3 Technical Data” to page 33) which replicates the Hi, Comfort T100 thermostat relays linked to it. It is ON if at least 1 of the Hi, Comfort T100 relays is ON, and OFF if all of the Hi, Comfort T100 relays are OFF. The WiFi Box can be wired to the boiler OTBus connection. This transforms the WiFi Box into a wireless receiver of anOTBus command. All of the information available in the Hi, Comfort T100 via the OTBus connection is repeated to the receiver which wires it to the boiler; it is therefore an example of complex radio frequency communication. The relay and OTBus outputs are identified on the WiFi Box by the term OUTPUTS and are available via a USB plug . The position and distinction between the 2 outputs on the USB plug are given below.

USB Outputs/Boiler:

• Dry contact TA
• ON/OFF relay
• max 2 A at 30 VDC
• OTBus protocol contact
• Never 230 V

Power supply:

• USB mini B 5V – 1A
• WiFi: IEEE 802.11 b/g/n – 2.4 GHz
• Radio frequency: 868 MHz
• Power consumption: 0.5 W

Two USB cables are also supplied, one to provide power via the USB power adapter and the other to connect the WiFi Box to the boiler. The cable to connect it to the electrical power supply is a USB mini.

The USB cable to connect the device o the boiler has an end with 4 terminals.

The black terminals are for the ON/OFF connection and are to be connected to the “boiler room thermostat” output. The red terminals are for the connection via OTBus and are to be connected to the “OTBus” output on the boiler.

If there is a Boiler RF receiver installed in the system, these do nothing other than repeat everything that happens in the WiFi Box on a RF receiver with the same outputs (ON/OFF and OTBus) which use the same wiring colours: Red = OTBus, Black = ON/OFF Following you find information on the boiler RF receiver and a description of its electric connection (6 wires)

WiFi Box connection via OTBus (only for boilers equipped with a compatible OTBus protocol) Connect the red wires of the USB cable to the boiler OTBus terminal (please consult the boiler installer manual). Should the boiler not be equipped with an OTBus terminal, you can use an OTBus connector provided in the WiFi Hi, Comfort T100 package (only for boilers without one). 9 Only one of the Hi, Comfort T100 system components (Hi, Comfort T100, WiFi Box or boiler RF receiver) must be connected to the boiler via cable via OTBus.
