Honeywell Thermostat: TH8320R & TH8321R VisionPro

Re: Temperature Adjustment

The TH8320R and TH8321R Redlink VisionPro Thermostats have the ability to adjust the sensed space temperature up or down -3 to +3 deg.

The sensed temperature can come from one of the following sources:

• Internal thermostat sensor
• Remote wired sensor connected to S1 terminals
• Redlink Wireless indoor sensor(s) - up to 6 sensors per stat
• Average between internal temperature and remote sensor(s)

What to check:

• Determine the location of the controlling sensor (may not be at the thermostat).
• Use an accurate thermometer to test the temperature at the controlling sensor.
  • Be aware that cold air from the wall may cause an inaccurate reading (especially outside or attic-space walls)
• If the sensed space temperature is inaccurate, you can adjust the sensed temperature through Installer Setup.

Adjusting Temperature:

• Go to thermostat Installer Setup
• Press "Next" until you get to Setup# 301 -  "CONTROL OPTIONS"
  • Select "Advanced Options"
• Press "Next" until you get to Setup# 1402 - "INDOOR TEMPERATURE OFFSET"
  • Use the Up and Down arrows to adjust the sensed temperature
• Press "Done"
• Answer "Yes" to the next two questions
• Press "HOME" to return to the Home Screen
