ONE 'DC60' FOR ONE, AND ONLY ONE, ROOFTOP
The DC60 displays only the values and information of the 'Roof-Top' on which the DC60 is connected.
TEMPERATURE MEASUREMENT
All LENNOX rooftop comes with a temperature sensor; it must be placed in the conditioned area.
But if the DC60 is placed in the area conditioned by the rooftop, that display is connected, it is possible, in this case, to use the
temperature measurement of the DC60.
To indicate the CLIMATIC™ 60 your choice, set the point 3213:
• ‘128' to use the measure of the 'DC60'
• ‘1 BM-B12' or '2 BM-B1' to use the remote probe
Note :
• for rooftop with a 'medium' CLIMATIC™ 60: connect the remote sensor between points B12 and GND, terminal block J18.
• for rooftop with a 'small' CLIMATIC™ 60: by default the CLIMATIC™ 60 control the return temperature measurement. If you want
to control on a room temperature measure, disconnect the return probe between points B1 and GND, terminal block J13. Connect
the remote sensor in place.
RELATIVE HUMIDITY MEASUREMENT
If the rooftop is designed to manage humidity, a box of combined sensors (temperature and humidity), supplied with the rooftop, it
must be placed in the conditioned area.
It's possible to use the temperature measurement DC60.
