Resistance Characteristics of Remote Sensors:
C7089U1006 Outdoor Sensor: Negative temperature coeffi-
cient (NTC) means that resistance decreases as the tem-
perature increases. See Table 12 in the Operation section
for sensor resistance characteristics.
C7189U1005 Remote Indoor Sensor: Negative temperature
coefficient (NTC), means that resistance decreases as the
temperature increases. See Table 13 in the Operation sec-
tion for sensor resistance characteristics.
Cool Indication:
VisionPRO®IAQ Comfort Systems show “Cool On” on the
thermostat screen when Cool is activated.
Heat Indication:
VisionPRO®IAQ Comfort Systems show “Heat On” on the
thermostat screen when Heat is activated.
Auxiliary Heat Indication:
VisionPRO®IAQ Comfort Systems show “Aux. Heat On” on
the thermostat screen when Auxiliary Heat is activated.
Calibration:
C7089U1006, C7189U1005 and VisionPRO
®
IAQ Comfort Sys-
tems are factory-calibrated and require no field calibration.
Interstage Differential:
VisionPRO®IAQ Comfort Systems operate with droopless
control. Once the thermostat senses that 1st stage is run-
ning at 90% capacity, the thermostat energizes 2nd stage.
Mounting Means:
VisionPRO®IAQ Comfort System: Thermostat mounts directly
on the wall in the living space using mounting screws and
anchors provided. Fits a vertical or horizontal 2 x 4 in. junc-
tion box.
THM5421C1008 Equipment Interface Module (EIM) mounts on
HVAC equipment or on a wall in the equipment room.
C7089U1006 Outdoor Sensor: Mounts outside of living space
with mounting clip and screws provided.
C7189U1005 Remote Indoor Sensor: Mounts directly on the
wall using mounting screws and anchors provided.
Cover Plate:
32003796-001 Cover Plate is used to cover marks left on the
wall by the old thermostat.
