2 Heater kit step control, error feedback and thermistor
connections
The EKMBUH*6V3 heater kit default operates as a 2-step 6 kW
heater. Step 1 delivers 3 kW heating capacity, step 2 delivers
6 kW heating capacity. These steps are controlled by the EKCB
indoor unit automatically.
In case only limited heater capacity is required, the
EKMBUH*6V3 heater kit can be installed as a single step 3 kW
heater as well.
- Possibility 1: 2 step, 6 kW installation
Connect all heater step control signals as shown on the
wiring diagram and in the figure below.
X2M - 22 Common
X2M - 23 Heater step 1 (3 kW)
X2M - 23a Heater step 2 (6 kW)
X15M - 1-2 Heater kit error feedback signal
X15M - 5-6 R12T thermistor
- Possibility 2: single step, 3 kw installation
Connect all heater step control signals as shown on the
wiring diagram and in the figure above, except the connection
of number 3 on the heater kit with number 23a on X2M at the
EKCB* indoor unit (heater step 2).
Connect the error feedback and thermistor signals to the
appropriate terminals.
3 Fix the cables with the cable ties inside the heater kit.
Make sure to ensure strain relief of the cable by correct use of
the PG nipples and nut (provided with the accessory bag).
Connections to be made in the EKCB indoor unit switch box
For details on connecting signals to the indoor unit refer to the
chapters "Overview of the indoor unit" and "Electrical wiring work" of
the outdoor unit installation manual.
1 Connect the indoor unit control signal to X2M 14, 15, 16.
2 Connect the heater kit error feedback signal to X801M 2, 5 of the
demand PCB.
7. START-UP AND CONFIGURATION
7.1. Pre-operation checks
After the installation of the heater kit, check the following before
switching on the circuit breaker:
■ Filled with water
Make sure that the heater of the heater kit is completely filled
with water.
■ Air purge
Make sure the air purge is open (at least 2 turns).
■ Field wiring
Make sure that the field wiring has been carried out according to
the instructions, according to the wiring diagram and according
to the European and national regulations.
■ Fuses and protection devices
Check that the fuses or the locally installed protection devices
are of the size and type specified in the chapter "12. Technical
specifications" on page 9. Make sure that neither a fuse nor a
protection device has been bypassed.
■ Earth wiring
Make sure that the earth wires have been connected properly
and that the earth terminals are tightened.
■ Internal wiring
Visually check the inside of the heater kit on loose connections
or damaged electrical components.
■ Power supply voltage
Check the power supply voltage on the local supply panel. The
voltage must correspond to the voltage on the identification label
of the heater kit.
■ Shut-off valves
Make sure all necessary shut-off valves are open and water flow
is possible.
■ Fixation
Check that the heater kit is properly fixed.
■ Damaged equipment
Check the inside of the heater kit on damaged components or
squeezed pipes.
Once all checks are fulfilled, the heater kit and indoor unit must be
closed and only then they can be powered up.
Only relevant wiring is shown.
