General information
This installation manual concerns the indoor unit EKCBX008BBV3
and EKCBH008BBV3 of the Monoblock units of the GBS Altherma
series.
The Monoblock units exist out of an outdoor installed unit (EBHQ)
and an indoor installed (wall mounted) unit (EKCB (this manual)).
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).
A user interface is standard supplied with the unit to control your
installation.
Heating/cooling units and heating only units
The monoblock unit range consists of two main versions: a
heating/cooling version (uses EKCBX indoor unit) and a heating only
version (uses EKCBH indoor unit), both available in 2 capacity sizes:
6 kW (EBHQ006) or 8 kW (EBHQ008).
3.2.
Combination and options
Possible combinations
Both versions (heating only and heating/cooling) are optionally
delivered with a backup heater kit (EKMBUH) 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. The
backup heater factory set capacity is 6 kW, however, depending on
the installation, the installer can limit the backup heater capacity to
3 kW. The backup heater capacity decision is a mode based on the
equilibrium temperature, see scheme below.
■
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 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 EKBPHT08BA (option)
■
Remote thermostat kit (option)
An optional room thermostat EKRTWA, EKRTR1 or EKRTETS
can be connected to the indoor unit. Refer to the installation
manual of the room thermostat for more information.
To obtain more information concerning these option kits, please
refer to dedicated installation manuals of the kits.
Connection to a benefit kWh rate power supply
This equipment allows for connection to benefit kWh rate power
supply delivery systems. Full control of the unit will remain possible
even in case the benefit kWh rate power supply is of the type that
power supply is interrupted. Refer to
supply/Local shift value weather dependent" on page 33
details.

Scope of the manual
This manual describes the procedures for handling, installing and
connecting the EKCB units. This manual has been prepared to
ensure adequate maintenance of the unit, and it will provide help if
