2. G

The precautions listed here are divided into the following four types. They all cover very important topics, so be sure to follow them carefully.

ENERAL

DANGER: ELECTRICAL SHOCK

Switch off all power supply before removing the switch box service panel or before making any connections or touching electrical parts.

Do not touch any switch with wet ﬁngers. Touching a switch with wet ﬁngers can cause electrical shock. Before touching electrical parts, turn off all applicable power supply.

To avoid electric shock, be sure to disconnect the power supply 1 minute or more before servicing the electrical parts. Even after 1 minute, always measure the voltage at the terminals of main circuit capacitors or electrical parts and, before touching, be sure that those voltages are 50 V DC or less.

When service panels are removed, live parts can easily be touched by accident. Never leave the unit unattended during installation or servicing when the service panel is removed.

DANGER: DO NOT TOUCH PIPING AND INTERNAL PA RT S

Do not touch the refrigerant piping, water piping or internal parts during and immediately after operation. The piping and internal parts may be hot or cold depending on the working condition of the unit.

Your hand may suffer burns or frostbite if you touch the piping or internal parts. To avoid injury, give the piping and internal parts time to return to normal temperature or, if you must touch them, be sure to wear protective gloves.

WARNING

Never directly touch any accidental leaking refrigerant. This could result in severe wounds caused by frostbite.

Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may be hot or cold, depending on the condition of the refrigerant ﬂowing through the refrigerant piping, compressor, and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature or, if you must touch them, be sure to wear proper gloves.

AFETY

PRECAUTIONS

CAUTION

Do not rinse the unit. This may cause electric shocks or ﬁre.

3. I

NTRODUCTION

3.1. This manual

This manual describes how to start up and switch off the unit, set parameters and conﬁgure the schedule timer by means of the controller, maintain the unit and solve operational problems.

CAUTION

For "Checks before initial start-up" and "Initial start-up" procedures refer to the installation manual of this unit.

3.2. This unit

These units are used for both heating and cooling applications. The units can be combined with Daikin fan coil units, ﬂoor heating applications, low temperature radiators, domestic hot water tank (option) and solar kit (option).

Heating/cooling units and heating only units

The monoblock unit range consists of two main versions: a heating/cooling (uses EKCBX indoor unit) version and a heating only (uses EKCBH indoor unit) version.

Both versions are delivered optionally with a separate backup heater for additional heating capacity during cold outdoor temperatures. The backup heater also serves as a backup in case of malfunctioning of the unit and for freeze protection of the outside water piping during winter time.

Datacable (obligatory option)

The EKCOMCAB1 thermistor interconnection cable must be connected to allow communication between the indoor unit and outdoor unit.

Domestic hot water tank (option)

An optional EKHW* domestic hot water tank with integrated 3 kW electrical booster heater can be connected to the indoor unit. The domestic hot water tank is available in three sizes: 150, 200 and 300 litre. Refer to the domestic hot water tank installation manual for further details.

Solar kit for domestic hot water tank (option)

For information concerning the EKSOLHW solar kit, refer to the installation manual of that kit.

Digital I/O PCB kit (option)

An optional EKRP1HB digital I/O PCB can be connected to the indoor unit and allows:

remote alarm output

heating/cooling ON/OFF output

bivalent operation (permission signal for the auxiliary boiler)

Refer to the operation manual of the indoor unit and to the installation manual of the digital I/O PCB for more information.

Refer to the wiring diagram or connection diagram for connecting this PCB to the unit.

Bottom plate heater EKBPHT (refer to the installation manual)

(option)

Remote thermostat kit (option)

An optional room thermostat EKRTW, EKRTWA, or EKRTR can be connected to the indoor unit. Refer to the installation manual of the room thermostat for more information.
