8.8.3 Wiring the boiler to the indoor unit
For the most eicient operation, the indoor unit should be
connected to a boiler that supports OpenTherm communication.
Standard on/o potential free switching is also possible.
1. Connecting an OpenTherm boiler.
Using the included 6-pole green connector, wire the boiler
OpenTherm connections to screw terminals 1 and 2 and then
push this into position X2 of the indoor unit, as shown in the
adjacent illustration (1).
(The OpenTherm connections are not polarity specific)
Additional info for boiler settings via OpenTherm:
► Set the maximum target temperature of the boiler to 80ºC.
► If underfloor heating is used, with no mixing valve then set
the maximum target temperature of the boiler 20ºC higher
than the maximum target temperature of the Xtend (see
§11.6 (P120 and P194).
► Set the boiler maximum output to calculated heat loss
required (for example: 10kW)
► Set both the minimum and maximum pump capacity of the
boiler to 50%.
2. Connecting an ON/OFF boiler.
Using the 9-pole green connector X3 wire the boiler
ON/OFF connections to the push tabs 7 and 8 of the indoor unit,
as shown in the adjacent illustration (2).
The connection must be potential-free failure to comply
will result in irreparable damage being caused.
When doing this set P066 to ‘4‘ (ON/OFF control)
and P121 to ‘3‘ (Relay output). See §11.6.
Additional info for boiler settings via ON/OFF:
► Set the maximum target temperature of the boiler 10ºC
higher than the maximum target temperature of the Xtend
see §11.6. (P194).
► Set the boiler maximum output to calculated heat loss
required (for example: 10kW)
► Set both the minimum and maximum pump capacity of the
boiler to 50%.

8.8.4 Wiring the indoor unit to an existing boiler
Connecting the wires to the correct boiler terminals depends on
the make and model of the boiler that the hybrid system is being
combined with.
1. Remove the origional thermostat wiring from the existing
combination boiler.
2. Now connect the indoor unit wiring to the resulting
connection within the boiler. (previously the thermostat; see
point 1 or point 2)
3. If necessary, consult the installation instructions for the
boiler in question.
NOTES
► When removing the wiring from the OpenTherm
or ON/OFF thermostat terminals within the boiler
you then create a pathway for the indoor unit
connections.
(ON/OFF boiler connections must be potential-free)
