It is possible to connect an electric coil (duct heater) of a maximum capacity of 5 kW in
line with the MINOTAIR main distribution conduit. The selected coil model must be
one that is able to modulate its intensity according to the actual airflow and using the
coil outlet temperature as the reference point. The reference temperature should be
set between 40°C and 50°C (104°F and 122°F) in a heating application or set less than
3°C (37°F) in a preheating application.
•
In the case of an electric coil, terminal "W" of the MINOTAIR controls the coil (see Figure
16). Ensure the MINOTAIR auxiliary heating option is set to "YES" in the "Temperature"
menu while specifying that the fan source is the MINOTAIR itself and not that of
another auxiliary device such as a furnace.
•
In the case of an electric coil, its 24 VAC "common" control wire must be connected to
the "C" terminal on the MINOTAIR (see Figure 16).

It is possible to connect a heat pump to the MINOTAIR. In this case, there must be a 120 VAC
relay (not supplied) that will connect in parallel with the reversing valve (Terminal NO2 on
the microcontroller) located inside the MINOTAIR which will then act as "O" terminal or "B"
according to the heat pump model. You have to choose the relay according to whether an
"O" terminal (normally open relay) or "B" terminal (normally closed relay) is required.
•
In the case of a heat pump, MINOTAIR terminal "W" is used to control the auxiliary heating
of the heat pump "AUX", which in this case is essentially the third stage of heating.
•
In the case of a heat pump, MINOTAIR terminal "Y" is used to control the compressor
"COMP (Y)" of the auxiliary heat pump.
•
In the case of a heat pump, its 24 VAC "common" control wire must be connected to
the "C" terminal on the MINOTAIR.
