Screw Terminal Arrangement
The screw terminals are arranged as follows.
Figure 5. Screw terminal diagram
Observe the following wiring considerations and requirements:
• If the same power source is used for auxiliary heating stages, insta
ll jumper across RC and RH.
Maximum current is 2.0 amps.
• If auxiliary output is used to toggle occupancy of the electronic control card inside the
equipment, configure the
re
lay parameter (Aux cont) to the N.O. setting. A second relay can be
added for additional functionality of the occupancy output.
• Electromechanical contacts are to be used w
ith the digital inputs. Electronic triacs cannot be
used as a means of switching for the input. The switched leg to the input for the input to activate
is terminal C (common).
• The transformer of the unit provides power to the therm
ostat and the
additional loads that will
be wired to the thermostat.
