RedLINK Communication:
Frequency: 900 Mhz frequency range
Re-Sync Time: RedLINK devices re-establish communica-
tion within 6 minutes after AC power resumes.
Temperature Setting Range:
Heating: 40 to 90 °F (4.5 to 32 °C).
Cooling: 50 to 99 °F (10 to 37 °C).
Temperature Sensor Accuracy:
± 1.5 F at 70 F (0.75 C at 21.0 C)
Humidification Setting Range:
10% to 60% RH.
Dehumidification Setting Range:
40% to 80% RH.
Humidity Display Range:
0% to 99%.
Humidity Sensor Accuracy:
± 5% RH from 30% to 50% RH at 75 F.
Cool Indication:
VisionPRO® 8000 with RedLINK™ displays “Cool On” when
the thermostat turns the cooling on.
Heat Indication:
VisionPRO® 8000 with RedLINK™ displays “Heat On” when
the thermostat turns the heating on.
Auxiliary Heat Indication:
VisionPRO® 8000 with RedLINK™ displays “Aux Heat On”
when the thermostat turns the auxiliary heat on.
Interstage Differential:
Comfort:
The thermostat keeps the indoor temperature
within 1 degree of the setpoint (droop less control). The
thermostat turns on stage 2 when the capacity on stage
1 reaches 90%.
When the interstage differential is set to 1.0 or higher, the
thermostat stages the equipment based on how far the
indoor temperature is from the setpoint (ISU 303 to
309). See page 28 for more information.
Clock Accuracy: 1 minute per month at 77 °F (25 °C). ± 2
minutes per month over the operating ambient tem-
perature range.
Mounting Means:
Thermostat mounts directly on the wall in the living space
using mounting screws and anchors provided. Fits a
horizontal 2 x 4 in. junction box.
Equipment Interface Module (EIM) mounts on HVAC
equipment or on a wall in the equipment room.
