AUX inputs
SMO 40 has software controlled inputs for connecting
the switch function or sensor. This means that when an
external switch function or sensor is connected to one of
six AUX connections, the correct function must be selected for the correct connection.
For further information see the Installer's manual.
The following functions can be controlled:
• Blocking of additional heat and/or compressor
• Tariff blocking
Extra climate system
This function requires accessory ECS 40/ECS 41. A shunt
valve, supply and return sensor and a circulation pump
are connected to a second heating circuit with a lower
temperature demand (e.g. underfloor heating system).
The temperature in the extra climate system is controlled
by the heat pump and the shunt valve by offsetting the
heat curve (each climate system has its own heat curve),
room sensor or room unit. Up to 3 extra climate systems
can be connected to SMO 40.
Temporary lux (extra hot water)
If an immersion heater is installed in the tank it can be
used to raise the temperature of the hot water, to a
temperature that exceeds the operating range of the
heat pump. In addition, it can be permitted to produce
hot water, at the same time as the heat pump prioritises
heating.
Mixer valve
A temperature sensor reads the temperature of the outgoing hot water to the domestic hot water and adjusts
the mixing valve from the water heater until the set temperature has been reached.
Hot water circulation (VVC)
One pump can be controlled for the circulation of the hot
water during selectable periods.
Sun
This function requires accessory Solar 40/42 as well as a
pump station. The solar panel can be used to heat the
hot water.
