Connection Of The Thermostat Cable - Daikin Altherna Serie Manual De Instalación

Procedure
1 Using the appropriate cable, connect the power circuit to the
main circuit breaker as shown on the wiring diagram and in
figure 2.
2 Connect the earth conductor (yellow/green) to the earthing
screw on the X1M terminal.
3 Fix the cable with cable ties to the cable tie mountings to ensure
strain relief. (Positions are marked with
Note: only relevant field wiring is shown.
4 If the backup heater capacity is to be set lower than the default
value (6 kW), this can be done by reconnecting wires according
to following figure. The backup heater capacity is now 3 kW for
V3 models or 2 kW for W1 models.

Connection of the thermostat cable

Connection of the thermostat cable depends on the application.
See also "Typical application examples" on page 6 and "Room
thermostat installation configuration" on page 18 for more information
and configuration options on pump operation in combination with a
room thermostat.
Thermostat requirements
Power supply: 230 V AC or battery operated
Contact voltage: 230 V.

Connection of the valve control cables
Valve requirements
Power supply: 230 V AC
Maximum running current: 100 mA
Wiring the 2-way valve
1 Using the appropriate cable, connect the valve control cable to
the X2M terminal as shown on the wiring diagram.
Wiring is different for a NC (normal closed) valve
NOTE
and a NO (normal open) valve. Make sure to
connect to the correct terminal numbers as
detailed on the wiring diagram and illustrations
below.

2 Fix the cable(s) with cable ties to the cable tie mountings to
ensure strain relief.
Wiring the 3-way valve
1 Using the appropriate cable, connect the valve control cable to
the appropriate terminals as shown on the wiring diagram.
Two types of 3-way valves can be connected. Wiring
is different for each type:
"Spring return 2-wire" type 3-way valve
The 3-way valve should be fitted as such that
when the 3-way valve is idle (not activated), the
space heating circuit is selected.
"SPST 3-wire" type 3-way valve
The 3-way valve should be fitted as such that
when terminal ports 9 and 10 are electrified, the
domestic hot water circuit is selected.

Connection to a benefit kWh rate power supply
Electricity companies throughout the world work hard to provide
reliable electric service at competitive prices and are often authorized
to bill clients at benefit rates. E.g. time-of-use rates, seasonal rates,
Wärmepumpentarif in Germany and Austria, ... .
This equipment allows for connection to such benefit rate power
supply delivery systems.
Consult with the electricity company acting as provider at the site
where this equipment is to be installed to know whether it is
appropriate to connect the equipment in one of the benefit kWh rate
power supply delivery systems available, if any.
When the equipment is connected to such benefit kWh rate power
supply, the electricity company is allowed to:
interrupt power supply to the equipment for certain periods of
time;
demand that the equipment only consumes a limited amount of
electricity during certain periods of time.
